Abstract

We show that it is possible to use backward optical parametric oscillation in GaSe to obtain tunable output in the 13–20-μm range with the minimum threshold intensity as low as a few 108 W/cm2. We may be able to use this configuration to achieve large amplification factors for a coherent weak beam in the far-infrared region. It is also possible to generate coherent far-infrared waves in the presence of pump and signal waves.
