An All-Solid-State Chirped Source for Coherent Optical Radar
Abstract
A low-noise, high-power, single-frequency, solid-state laser harmonically converted to the green is required to pump a single-frequency, singly-resonant, chirped, optical parametric oscillator. As work toward this new frequency agile source we have built and injection locked an 18 watt Nd:YAG slave laser with a 40 mW master laser to produce single frequency operation, generated 6.5 watts of 532 nm radiation at 36% efficiency by resonant second harmonic generation, and measured spectral and spatial mode characteristics of this laser. Toward an all-solid-state version of this laser we have designed a diode-laser-pumped Nd:YAG laser. All subsystems of this laser have been built and tested and the final construction of the laser is currently underway. In addition, we have built both a pulsed singly resonant optical parametric oscillator, and a low threshold cw doubly resonant optical parametric oscillator that operated at 80% conversion efficiency in a single axial mode.
