New compact high repetition rate lasers for LIBS

By Håkan Karlsson, Elizabeth Illy, Bertrand Noharet & Tania Irebo
3 June 2014

White Paper Lead ImageLaser-induced breakdown spectroscopy (LIBS) is an atomic-emission spectroscopy technique that enables rapid chemical analysis of a wide range of materials ranging from metals, semiconductors, glasses, biological tissues, plastics, soils, thin-paint coating, and electronic materials. The LIBS technology has received substantially increased interest over recent years as a result of the development of more compact, even hand-held, systems that enables in-field use and construction of tools for on-line material analysis. This development has been made possible by the increased availability of more compact and industrial-grade system components including lasers, spectrographs and CCD cameras. In this application note we present how a new class of compact lasers with multi-kHZ pulse repetition rates enables significant reduction of the footprint of a LIBS system.

Ophir Pyro OEM Sensors – What options are available?

By Julian Marsden
6 May 2014

White Paper Lead ImagePyroelectric sensors have been used widely in the laser industry for many years to measure energy. They allow measurement of individual pulse energy or pulse-to-pulse variation for rapidly pulsing lasers, something that cannot be done with photodiode or thermal sensors. They also are not limited to visible or near-IR wavelengths like photodiodes, allowing measurements into the deep IR and THz regions. Ophir has recently introduced a new series of Pyroelectric OEM sensors based on the “PE-C” line of standard Pyroelectric sensors, which were introduced in 2011. This document presents the various options available to customers, lists the advantages of the new series over existing products, and mentions the capabilities of the new line.

Narrow line diode laser stacks for DPAL pumping

By DILAS
1 May 2014

White Paper Lead ImageDiode pumped alkali metal vapour lasers (DPALs) offer the promise of scalability to very high average power levels while maintaining excellent beam quality, making them an attractive candidate for future defence applications. A variety of gain media are used and each requires a different pump wavelength: near 852nm for caesium, 780nm for rubidium, 766nm for potassium, and 670nm for lithium atoms. The biggest challenge in pumping these materials efficiently is the narrow gain media absorption band of approximately 0.01nm.
