A second harmonic generation (SHG) of Nd:YAG or Nd:glass is typically utilizing to pump the Ti:sapphire chirped-pulse amplification laser system for realizing a high intensity pulse laser. CsB
O
(CBO) crystal has a potential to obtain the high energy SHG because the effective nonlinear coefficient and damage threshold are high. In this presentation, we have demonstrated efficient frequency doubling of high energy fundamental Nd:YAG laser pulse energy of the 1.2 J with a conversion efficiency of 60% at a 10 Hz using high optical quality top-seeded solution growth CBO (TSSG-CBO) crystal. These results indicate that TSSG-CBO is a good candidate material for high energy SHG of Nd-doped lasers at the several J level with high repetition.

Using a partially deuterated KDP crystal for an optical parametric amplifier, we demonstrated ultrabroadband optical parametric chirped-pulse amplification of more than 250 nm bandwidth at a center wavelength of 1050 nm. We numerically show how to control the broadband phase matching conditions at different wavelengths to match center wavelengths of suitable broadband seed sources by adjusting the deuteration level in partially deuterated KDP.
