Abstract

By injecting single subnanosecond pulses into a latent ring-laser oscillator, it is possible to generate highly reproducible intense trains of short pulses from a solid-state laser. In this way, 12-psec pulses are available from a high-repetition-rate Nd3+:YAG laser, whereas Nd3+:phosphate glass reliably produces pulses of <3-psec duration. Further compression of the Nd3+:YAG laser pulses can be accomplished by the insertion of a passive phase modulator into the cavity, yielding pulses of ≥5-psec duration and >3-cm−1 bandwidth.
