Control of the duration of ultrashort pulses emitted from a Q-switched solid-state laser

摘要: An experimental investigation was made of a new method for controlling the duration ultrashort pulses in widest possible range (for shorter than resonator length) from axial period to reciprocal width gain band active medium. The ensured complete reproducibility all parameters output radiation. A ruby laser with saturable absorber emitted ~35 psec when ~1.5 nsec were injected outside into (the reduction pulse thus exceeded factor 40). emission spectrum then close limit an exponential envelope.
