Paper Abstract

We have developed a laser vibrometer based on a Nd:YVO4/YVO4/KTP monolithic single-frequency green laser operating at 532 nm with narrow linewidth of radiation (~85kHz). Two configurations of laser Doppler vibrometer have been investigate - with so-called single- and double-frequency Bragg shifts. Measurement of heterodyne signals as a mixing result of scattered and reference beams has been performed. In both configurations we have obtained signals with high S/N ratio >30 dB with Resolution Bandwidth RBW = 200 kHz for a vibrometer output power of 3 mW. In our opinion, stable single-frequency solid-state green lasers provide new opportunities for the development of miniature laser vibrometry.
