Abstract :
Advances in nonlinear crystals and pumps prepare optical parametric devices (OPDs) for service as a reliable, broadly tunable light source. Fundamental optical parametric processes in crystals are examples of nonlinear, multibeam mixing processes. The processes that have recently experienced an explosion of interest involve conversion of a pump photon at high frequency into two photons at lower frequencies. The spectrum of frequencies in the downconverted beams is not restricted by this relation.<>
