Abstract

A cavity-dumped Nd:YAG laser is used to generate optical pulses for a laser communication link. Data are encoded by pulse interval modulation. Three stacks of GaAs diodes continuously pump a Nd:YAG rod, which is coated for high internal reflection on one end. A polarizing beam splitter reflects s-polarized light at a 90° angle to form an L-shaped laser cavity. A lithium niobate modulator modulates the circulating power by polarization retardation in response to an applied voltage.
