A precise knowledge of the thermal effects in laser crystals is very important for high-power laser design, but some relevant parameters are most often neglected in their calculation. In this paper, with the example of transversally pumped, high-powe

This study focuses on the influence of three operating parameters (gas flow rate, laser repetition rate, and fluence) on the number and size distributions of nanoparticles generated by laser ablation of acrylic paint. These particles, produced by gas

Leak detection and localization is an issue for facility and population safety and security. The paper shows that low leak rates of methane, down to 5 10−9mbar.L/s, are detected by OF-CEAS technique under atmospheric pressure.

The laser system is by far the most expensive part of a laser-produced plasma (LPP) EUV source. Thus LPP source designers have not only to optimize the technical performances of the lasers but also cost, efficiency, reliability, redundancy and indust

It is very difficult to achieve both high-power and low divergence lasing at once in cw or high-repetition rate lasers because thermal effects limit their efficiency. But as these effects are stable over time, a passive correction is conceivable. In

The objectives were to provide a low cost, air cooled and robust laser. Nd:YVO/sub 4/ crystal is now a current choice as a lasing material for diode-pumped solid state laser because of its high gain, high absorption and also linearly polarized output

Within the PREUVE project, the GAP of CEA Saclay has developed an EUV source that should meet (alpha) -tool specifications by the end of this year. In particular, a laser-produced plasma source has been developed that uses a dense and confined xenon

We describe the current status of the ELP-OA project in which we try to demonstrate in practice that it is possible to measure the tilt of a wave front using only a polychromatic laser guide star and no natural guide star. The first phase of ELP-OA,

Adaptive optics at astronomical telescopes aims at correcting in real time the phase corrugations of incoming wavefronts caused by the turbulent atmosphere, as early proposed by Babcock. Measuring the phase errors requires a bright source, which is l
