Paper Abstract

Lasers for space applications require miniaturized high power components that can be operated at low voltages. RbTiOPO4 (RTP) is a highly efficient electro-optical material, which is used in particular for the realization of low voltage and high repetition rate Pockels cells. RTP can be operated in two crystal orientations (x-cut and y-cut). In both cases, the incoming linear polarization is oriented at 45o to the z-direction. In this study, laser damage is investigated in RTP crystals. More precisely, we focus on the correlation between the laser damage characteristics and the used crystal orientation. The laser damage tests were carried out at 1064 nm with a standard 6 ns Q-switched Nd:YAG laser and the polarization was oriented as for Pockels cell operation at 45o to the z-axis of the crystals. This work reveals that the Laser Induced Damage Threshold (LIDT) is two times higher for x-cut than for y-cut RTP crystals. Reflection and transmission measurements show that this LIDT anisotropy can not be explained by an evident loss mechanism like Stimulated Raman Scattering (SRS).
