Minimizing risk for laser damage due to transverse stimulated raman scattering in large-aperture KDP/DKDP plates for polarization control at 3w
On demand starting 12 October 2021
The 3-D dependence of the spontaneous Raman scattering cross section for crystal configurations pertinent for the evaluation of the transverse stimulated Raman scattering (TSRS) in KDP and DKDP polarization control optics for large-aperture laser systems is investigated. TSRS can generate a transversely propagating parasitic beam capable of damaging both the optic and its mount. The results presented in this work can help optimize the design and manufacture of such optics where the TSRS gain is suppressed.
