Abstract

A laser spectrometer includes a tunable laser assembly, a periodically-poled nonlinear optical crystal, with parallel polished input and output end faces, and a mechanism for controlling an entrance location of a pump input beam of the tunable laser on the input end face of the periodically-poled nonlinear optical crystal, such that the pump input beam traverses different grating periods of the periodically-poled nonlinear optical crystal.
