Abstract

Nd: YAG radiation at 1.064μm is converted to the 8-12μm region, using two consecutive OPOs. The first conversion stage: 1064nm→1574nm is based on a non-critically phase matched KTP crystal. The second stage: 1574nm→8-12μm is an angle tuned AgGaSe₂ OPO. In order to enable high-energy output we use large diameter pumping beams. Despite the large diameter beams, a low divergence is achieved on both OPOs by using unstable confocal resonators that reduce the divergence of the oscillating beams each round trip. 1. A. Kaz, L.R Marshall, Scaling optical parametric oscillators in power, energy, and beam quality, OSA Proc. ASSL 20, 307 (1994).
