ABSTRACT:
A method for efficiently controlling sum frequency mixing and second harmonic generation within Q-switched laser oscillators. A nonlinear crystal is placed at either the intersection point of two otherwise independent laser oscillators (in the case of sum frequency mixing) or within a single laser resonator (in the case of second harmonic generator). During the build-up phase of the oscillator temporal development. (i.e., after the Q-switch has been opened but before the laser has reached threshold), a nonlinear optical crystal controlled by high voltage is employed to significantly reduce the efficiency of the frequency conversion process. In a preferred embodiment, the nonlinear optical crystal reduces the efficiency of the birefringent nonlinear optical process by spoiling the dephasing of the multi-wave interaction. After threshold has been reached in the resonant cavity, the conversion efficiency is increased at some desired rate. As a result, the extracted light at the converted frequency has one or more of a number of desirable properties, including: increased net conversion efficiency; reduced pulse-to-pulse temporal fluctuations (jitter); and/or a controlled temporal shape.
