The influence of the pump intensity profile on the performance of a mid-IR ZGP RISTRA OPO at 6.45 µm is studied for a flat-top pump profile and compared to a Gaussian pump distribution at the same pump peak fluence of 0.81 J/cm2. Due to a coherent b

CdSiP 2 (CSP) is a very promising nonlinear crystal for the mid-IR spectral range with a nonlinear coefficient slightly larger than that of ZnGeP2 (ZGP). In contrast to ZGP, CSP is phase-matchable and can be employed in 1.064-μm pumped optical param

Idler beam quality at 6.3 µm from HgGa2S4 OPO is compared for linear, planar ring and RISTRA cavities. The last one produces smooth, circular profile and much higher focal fluence.

The beam quality of the idler output of a 1064 nm pumped OPO based on CdSiP2 is compared for linear and Rotated Image Singly-Resonant Twisted RectAngle (RISTRA) cavities. For similar mirrors and cavity round trip times the RISTRA cavity yielded 64 μ

Technologies for Optical Countermeasures VII.
For some medical fields in laser surgery and as a pump source for nonlinear materials to generate mid-IR radiation, e.g. for countermeasure applications, it is very useful to have a solid-state laser with high pulse energy at 2 μm. The rare earth io
