Title: High attenuating external cavity for picosecond-tunable pulse generation from gain/Q-switched laser diodes

Abstract

The authors analyze in detail the behavior of gain/Q-switched Fabry-Perot laser diodes coupled to a highly attenuating, selective external cavity. Radical differences are shown as compared to the case of strong external feedback used in mode locking. Actually, they evidence a strong analogy with the case of pulsed lasers with a small quasi-monochromatic injection signal. Unlike previous experiments on laser diodes with selective external cavity, strong chirping is observed in single-mode emission, leading to tunable picosecond pulses after compression. Experiments are carried out on two types of devices. Picosecond pulses with very high tunability (40 nm) and repetition rates ([gt]10 GHz) are obtained from 1.3 [mu]m gain-switched laser diodes, the minimum pulsewidth being 2.5 ps. Ultrashort ([approximately]1 ps), high-power ([gt]5 W) tunable pulses are achieved with 0.8 [mu]m Q-switched lasers.
