Q -switching cleaved-coupled-cavity laser with an integrated intracavity modulator

We describe fabrication and performance of a Q-switching cleaved-coupled-cavity laser with an integrated intracavity modulator. The pulse repetition frequency of this 3-section device was tunable between 320 and 450 MHz with an external microwave injected signal, the modulation depth of the pulsations was 80–100% with a nearly single-longitudinal-mode output spectrum, and the Q-switched light pulses were modulated by a pseudorandom PCM signal at 322 Mbit/s.
