Abstract:

Tunable optical parametric amplifiers and oscillators that are pumped by the light from a tunable laser source are disclosed. One possible embodiment uses a tunable solid-state laser pump and an OPA medium or nonlinear crystal, such as potassium titanyl phosphate KTP or barium borate BBO or lithium borate LBO. The second harmonic output from a tunable solid-state laser is also used to pump the OPA medium. A singly or doubly resonant cavity design is preferably used to reduce the oscillation threshold (i. e. , the required pump beam power) of the OPO.
