Abstract

Since the first reported work of developing the self-injection technique in solid-state YAG and dye lasers^1,2 for generating high-energy pulses in the nanosecond range, several other groups have further demonstrated the usefulness of this technique to other kinds of lasers such as f iashlamp pumped dye lasers and unstable YAG oscillators.^3,4 The present study represented a new application of this self-injection technique for generating short optical pulses which are continuously temporal-tunable from 10 nsec to 5 psec. Nanosecond and picosecond pulses generated in the present experiments showed excellent amplitude stability and temporal synchronizability and with a higher output energy; if preserved the same characteristics as those observed previously in other short-pulse oscillators using the self-injection technique.
