Abstract

Transverse stimulated raman scattering (TSRS) in potassium dihydrogen phosphate (KDP) and deuterated potassium dihydrogen phosphate (DKDP) plates for polarization control is a well-recognized limitation, giving rise to parasitic energy conversion and laser-induced damage. TSRS amplification is a coherent process that grows exponentially and distributed nonuniformly in the crystal and at the crystal surfaces. To understand the growth and spatial distribution of TSRS energy, a modeling approach was developed to simulate operational conditions in inertial confinement fusion-class laser systems. The result helps assess upper limits for operational conditions and guide possible ways to suppress the TSRS gain.
