Effect of idler absorption in pulsed optical parametric oscillators
Absorption at the idler wavelength in an optical parametric oscillator (OPO) is often considered detrimental. We show through simulations that pulsed OPOs with significant idler absorption can perform better than OPOs with low idler absorption both in terms of conversion efficiency and beam quality. The main reason for this is reduced back conversion. We also show how the beam quality depends on the beam width and pump pulse length, and present scaling relations to use the example simulations for other pulsed nanosecond OPOs.

Midinfrared laser source with high power and beam quality
A simple scheme for generation of high power in the midinfrared is demonstrated. By using a thulium-doped fiber laser emitting at to pump a Q-switched Ho:YAG laser, we obtained at a pulse repetition rate with excellent beam quality. The output of this laser was used to pump a doubly resonant zinc germanium phosphide based optical parametric oscillator, and we obtained average power in the range with .- 1 June 2006
