Berliner Glas (www.berlinerglas.com) will present a broad spectrum of tailor-made OEM solutions at Photonics West. The company provides optical key components, assemblies and systems as well as refined technical glass. The company develops, produces and integrates optics, mechanics and electronics into system solutions for its customers. As OEM partners from prototyping to volume production, the Berliner Glas companies serve customers in various markets, the semiconductor industry, medical technology, metrology, laser and space technology, analytics, defence and the display industry.
The athermal DPSSL scheme developed by Cilas (www.cilas.com) allows laser operation that is intrinsically insensitive to variations in ambient temperature. The company will be exhibiting at the show.
Mobile laser applications (essentially military) can be quite demanding in terms of the laser architecture. Some of the demands placed on the laser include a requirement for instantaneous emissions over a wide operational range (climatic, vibration, shock), low divergence, low power consumption, and a compact housing so that they can be carried by soldiers.
Cilas has developed a family of Athermal OEM laser modules (ALaDem and MiniDem), which are 90mJ and 30mJ class respectively, 15ns, 20Hz Q-switched laser modules with high beam quality. These modules are passively cooled, very compact, ruggedised and have a very low power consumption.
Coherent (www.coherent.com) will show a new range of fibre-pigtailed (FP) lasers. The Sapphire FP lasers are compact, CW, visible lasers that offer a combination of low noise and output stability. These lasers are available at seven wavelengths (458nm, 488nm, 514nm, 532nm, 552nm, 561nm and 588nm), at output powers of up to 120mW. They are nominally configured with one metre of single-mode, polarisation-preserving fibre, terminating in a standard FC/APC 8° connector, simplifying their use in standalone applications or integration into OEM instruments.
Sapphire FP pigtailed lasers achieve a combination of low noise and output stability due to several factors. The first is the use of the Sapphire laser platform that delivers a circular output beam. Second is the use of a rugged permanent fibre-pigtailing using Permalign technology rather than an air-launched setup using multi-axis adjustable mounts. The design makes the fibre an integral part of the resonator plate featuring Permalign technology. As a result, Sapphire FP lasers deliver output stability (<±2% over 2 hours ± 3°C after warm-up), low noise (<0.25% RMS at 10Hz to 2MHz) and a broad ambient temperature operating range (10 to 40°C). In addition, a special fibre termination allows the operation of Sapphire FP lasers at short wavelengths and/or high powers without fibre degradation or damage.
Applications for Sapphire FP include the life sciences, metrology, and inspection. Typical examples are fluorescence-based techniques, where fibre delivery is commonly used to facilitate miniaturisation, such as flow cytometry or confocal microscopy.
EKSPLA (www.ekspla.com) is introducing the first commercial DPSS mode-locked picosecond laser with more than 25mJ pulse energy at 30ps pulse duration and 50Hz pulse repetition rate. The PL2230 laser has been designed primarily for applications that require stable laser pulses like laser spectroscopy, OPG pumping, remote laser sensing and satellite ranging. All pulse generation and amplification stages use only diode pumping (no flashlamps).
Due to the full DPSS pumping, the laser features excellent pulse-to-pulse stability and more than three years maintenance free operation of pumping heads (estimating eight operation hours per day). Pulse-to-pulse energy stability remains less than 0.5 per cent rms at 1064nm for a 2.5-25mJ output energy range. The required pulse energy can be set and afterwards fine-tuned in approximately 0.25mJ steps from a remote control pad or personal computer. Second (532nm), third (355nm) and fourth (266nm) harmonics generators are available as standard options.
Element Six (www.e6.com) will showcase its CVD synthetic diamond as an enabling technology for high power laser systems, highlighting the material’s benefits. These benefits include broad optical transmission spectrum, the highest known thermal conductivity and resilience. A commercially available engineering material, Element Six synthetic diamond exploits the material’s properties to deliver technical benefits for high power lasers. At Photonics West, Element Six will be conducting multiple demonstrations highlighting the thermal and mechanical capabilities of CVD synthetic diamond as well as its transparency— which includes hard X-rays and a very wide wavelength range from the ultra violet to the micro waves part of the spectrum.
Elforlight (www.elforlight.com) will be exhibiting its latest range of nanosecond wavelength shifted and tunable DPSS laser systems providing wavelength flexibility for photoacoustic imaging and other applications. A range of add-ons to the company’s high repetition rate solid-state lasers enable nanosecond kilohertz tunable sources across both visible and infrared wavelengths.
Raman lasers, OPOs and dye lasers provide flexibility over a range of energies from microJoule to milliJoules. Compact OPOs pumped at 1064nm allow near- and mid-IR outputs from 1400 to 4000nm with 1mJ energy and >1kHz repetition rate. Miniature dye lasers and OPOs provide tunable visible output at multi kHz repetition rates and several microJoules energies. Raman shifted outputs provide a number of useful wavelengths for blood or plaque absorptions at repetition rates of 5kHz or more.
The Fraunhofer Institute for Photonic Microsystems IPMS (www.ipms.fraunhofer.de) will be presenting an extremely miniaturised near-infrared spectrometer at Photonics West. This device enables analysis of gaseous, liquid and solid materials immediately on site instead of taking samples for lab analysis. The optical bench is smaller than a sugar cube and thus it might fit into mobile devices as well as in automated process analysis tools.
Hamamatsu Photonics (www.hamamatsu.com) will be introducing the latest range of Quantum Cascade Lasers (QCL) for laser gas analysis. Other detectors on display include photodetectors, image sensors, cameras and light sources, avalanche photodiodes, multi-pixel photon counters (silicon photomultipliers), hybrid photodetectors, linear array photomultiplier tubes, MEMS mirror and module and infrared detectors among others.

Hamamatsu will also introduce a new range of CCD, CMOS and InGaAs image sensors in linear and 2D formats.
Ibsen Photonics (www.ibsenphotonics.com) will show two new spectrometers. The Freedom spectrometers combine compactness (28 x 45 x 16mm) and low stray light performance and a 1nm resolution. The Rock NIR 900-1700 spectrometer offers higher throughput, typically four times higher than conventional spectrographs, due to a low f-number of 2.2 and its transmission grating. The Rock NIR is for OEM integrators of analytical instruments because of the flexibility in design. The spectrometers can be fitted with a range of different InGaAs detectors and supplied with or with-out electronics from Ibsen.
Idquantique’s id220-FR (www.idquantique.com) is for single photon detection in free-running mode (900 - 1700nm). It provides a solution for applications in which asynchronous photon detection is essential. The cooled InGaAs/InP avalanche photodiode and associated electronics have been designed for achieving low dark count and after pulsing rates in free-running mode. The module can operate at three detection probability levels of 10, 15 and 20 per cent with a dead time that can be set between 1us and 25us. Arrival time of photons is reflected by a 100ns TTL pulse available at the SMA connector with a timing resolution as low as 250ps at 20 per cent efficiency.
IPG Photonics' (www.ipgphotonics.com) GLR-100 laser is a new high-power, low-noise, single-mode CW green fibre laser, and will be displayed at the show. With an output power in excess of 100W, it is suited to industrial applications such as materials processing, solar cell manufacturing, semiconductor inspection and annealing and others.
Due to the combination of high wall-plug efficiency, 20-25 per cent and 90 per cent SHG efficiency, the laser requires no water-cooling for either the pump module or the laser head. Separation of IR and SHG stages makes these new CW green lasers scalable by using very powerful, well tried and tested single-frequency ytterbium fibre laser sources. Simplicity of design and extremely high wall-plug efficiency allow these green fibre lasers to be significantly cheaper and smaller than their solid-state counterparts, the company claims.
Jenoptik (www.jenoptik.com) will be presenting new products and advanced technologies in the fields of optics, lasers and infrared technology. Jenoptik will present the femtosecond laser JenLas D2.fs with improved parameters. Maintaining stable beam quality, the output power and pulse repetition rate of the laser have been increased to allow for faster material processing in industry and medical technology.
Scattermaster in Lambda Research (www.lambdares.com) is to have demonstrations of the laser-based Scatterscope3D scatterometer, specifically designed for process and quality control testing of surface texture, roughness, degradation, and testing of surfaces for water and environmental contamination. It is the first scatterometer portable enough to use directly on the assembly line or out in the field to test for environmental wear and aging.
Light scatter measurements over a range of angles provides a means to monitor texture over a number of roughness frequencies. The Scatterscope3D uses scatter measurement for simple pass/fail defect detection and involved diagnostic testing for quality assurance and manufacturing process testing.

The following versions are available: GaP photodiode (190-570nm), Si photodiode (200-1050nm) and InGaAs PIN photodiode (800-2200nm).
Laser Components (www.lasercomponents.com) will be exhibiting their pulsed laser diodes with fibre pigtails at Photonics West. The fast axis collimation lenses are assembled directly in front of the pulsed laser diode chip. The semi-automatic mounting setup means the fibres can be assembled to within just a few µm. This allows coupling efficiencies of >85 per cent to be achieved. Peak power levels of >100W out of the fibre can be reached, depending on the laser diode chip and fibre core diameter. Applications include laser scanners, measurement, fibre optic, medical, military and illumination technologies. These diodes can be used in military applications at temperatures between -40°C and +85°C, and are available at wavelengths of 905nm and 1550nm.
