Frequency-modulated Nd:YAG laser

Abstract
A frequency-modulated, single-mode Nd:YAG laser has been constructed that tunes up to 12 GHz. The laser incorporates a LiTaO3 electro-optic phase modulator with acoustic damping to provide a tuning sensitivity of 12 MHz/V and linear voltage-to-frequency conversion. A frequency excursion of 1.2 GHz has been generated with a rise time of 0.6 ns.
