Passively Q-switched solid-state lasers with intracavity optical parametric oscillators

Abstract: A rate-equation-based model that describes the behavior of a passively Q-switched solid-state laser containing an intracavity optical parametric oscillator (OPO) is developed. In such a laser there is no output at the fundamental or pump wavelength. When the OPO signal field begins to build up, it acts as a loss for the pump and thus cavity dumps the pump resonator. The model developed explains this behavior and enables one to select OPO parameters which optimize the system's performance. Application of the model to a compact, lightweight, eye-safe, laser range finder operating at 1.54 /spl mu/m is also described.

An intracavity optical parametric oscillator in a passively Q-switched laser

Abstract: A passively Q-switched intracavity KTiOPO/sub 4/ optical parametric oscillator was designed, fabricated, and tested. The model has been developed and its application to the design and operation of a very compact, lightweight, eyesafe laser has been demonstrated.
