P4 - Interferometric Heat-Load Sensing of High Power Solid Laser Medium

M. Baumgart, C. Glassl, A. Tortschanoff & G. Kroupa
Compact and reliable high-power lasers for applications in rough environments are increasingly demanded by industry. CTR’s HiPoLas® DPSS laser combines the advantages of high energies per pulse (>40 mJ) and long lasting operation in a compact, temperature and vibration resistant housing. Achieving high energy densities in such a miniaturized layout requires in-depth understanding of the processses occurring during pumping in the laser cavity. A novel, Fabry-Perot-interferometer based, sensing scheme now enables such in-situ measurements in...
