Jenoptik has launched a selection of laser products, including JenLas D2.fs, JenLasG100, JenLas disk IR 50, qcw diode lasers, scanning lens for laser materials processing, CaF2 microoptics, two-sided micro lens arrays and Jencolor.
With high repetition rate with repetition rates of 200kHz and pulse energies of 10μJ with a pulse duration of less than 400 fs, the JenLas D2.fs femtosecond laser is a new ultra-short pulse laser offering.
The low thermal load on the materials being processed the D2.fs can also be used in medical applications for treating biological tissues.
The JenLas D2.fs utilises thin-disk laser technologies for the regenerative boosting of ultra-short laser pulses with high power densities and consistent high beam quality. The high impulse energy of the D2.fs is achieved in this respect without the use of costly CPA technology
JenLasG100 – frequency-doubled thin-disk laser
Jenoptik has expanded its product line of 515nm frequency-doubled thin-disk lasers into the 100W class.
A new instrument is available now, providing a beam quality of M²=5 with pulse energies of some mJ. The laser is intended for such micro machining applications as cutting, drilling or engraving. Emitting at 515nm, it can easily handle materials like copper, too.
With a capability for adjusting the pulse length, the instrument offers some significant advantages for the optimisation of customer applications. It relies on the same novel-type technology as the JenLas disk IR 50.
JenLas disk IR 50 thin-disk laser with adjustable pulse length
Jenoptik has developed a product generation, based on established thin-disk laser technology. The first version is a 50W system that features excellent beam quality (TEM00, M²<1.2) in the infrared spectral range at 1030nm.
It can adjust pulse length, which is largely independent of pulse repetition rate and power settings. This laser can also decouple pulse length and pulse repetition rate, thus optimally adapting the required laser peak power to a given application.
The JenLas disk IR 50 is suited for micro material processing in an industrial environment. Flexible adjustment options provide several significant benefits in an environment where requirements are changing frequently (e.g. job shops, research institutes, etc.).
qcw diode lasers with pulse power of 300 W
Using a new generation of high-power diode lasers bars - fully optimised for quasi continuous wave (qcw) operation - Jenoptik Laserdiode has released higher output powers from qcw diode lasers at a wavelength of 808nm using passive cooling based on diode laser bars from its Jenoptik Diode Lab subsidiary.
For pulse durations up to 300μs and duty cycles up to 10 per cent the peak power can be as high as 300W. Fast axis collimation is available as well.
For the first time, based on this semiconductor material Jenoptik Laserdiode also presents passively cooled qcw stacks, which achieve peak powers up to 2.4kW. For these stacks fast axis collimation is in preparation as well.
Scanning lens for laser materials processing
The special features of the F-Theta scanning lens from Jenoptik are a high spot size consistency and a uniform output density across the entire scanning field. These properties are crucial for laser applications in the area of micro materials processing, for example in the precision cutting, scribing and labelling of various materials as well as in internal glass engraving.
The new F-Theta product range from the Optics unit covers 20 different lenses which have been optimised for the 266nm, 355nm, 532nm and 1,064nm wavelengths. The diffraction-limited optical design provides for field sizes in the range from 20mm to 431mm.
CaF2 microoptics for DUV and high-power applications
The Microoptics area, part of Jenoptik’s Optical Systems division, has improved its DUV materials processing capabilities.
Demonstrators of CaF2 micro lens arrays and CaF2 refractive Gaussian diffusers show efficiencies of more than 97 per cent and homogeneities of better than 94 per cent, with zero order measurements below detection limit.
The new product lines in CaF2 are targeted for the health care and life science market where excimer laser powers are increasing and long-term reliability is required. In addition, the semiconductor lithography market is using higher power levels in the DUV, thus requiring materials other than SiO2. Both product lines are ready for distribution at customer level.
High efficiency polymer two-sided micro lens arrays
Jenoptik Microoptics, part of Jenoptik Optical Systems division, enhanced its existing replication capabilities and announces the advancement of high performance plastic micro-optics.
Jenoptik, in combining Jenoptik Polymer System’s proprietary technologies of injection molding and Jenoptik Microoptics’ gray scale technology, can now provide high fill factor, highly efficient 2-sidedaspheric micro lens arrays with square or rectangular lens formats for laser based homogenisation in mass production for the display market.
These micro lens arrays have two sides with a centring accuracy of better than five microns, enabling better spatial and angular uniformity, giving homogenized illumination of standard and HD format light engines.
Jenoptik´s Optical Systems division offers colour sensor modules for device integration under the brand name Jencolor, optionally a software development kit DLL as well as the complete design and manufacturing services in electronics, optics and mechanics.
Jenoptik Polymer Systems, part of Jenoptik’s Optical Systems division, designs and manufactures high-performance electronic solutions for color measurement, adjustment and management, e.g. for power RGB LEDs for illumination and backlighting.
The Jencolor sensors are provided with superior quality and spectral sensitive interference filter on chip without aging. The sensors are temperature-stable, realize a high transmission / blocking and comply with the tri stimulus standard observer function CIE1931/DIN5033.
