A 15-fold reduction in the duration of YAG:Nd/sup 3 +/ laser pulses was achieved under conditions of active mode locking and Q switching at a pulse repetition frequency approx.1 kHz. Phase self-modulation in a single-mode quartz fiber waveguide of length 10 m resulted in broadening of the laser emission spectrum right up to approx.10 cm/sup -1/ at the waveguide exit. The pulses were then shortened in a system with a diffraction grating. The pulse duration was measured by a correlation system in which the second harmonic was generated.
