Abstract

The cavity length of a CW mode-locked Nd:YLF laser is detuned to investigate the effect of detuning on the output of the laser. Negative detunings of 0.4 to 2.4 μm result in periodic modulations of the pulse envelope. Further negative detunings of 2.4 to 3.4 μm produce undamped regular spikings, that is, stable self-Q-switching behavior with mode-locked pulses of 30~47 ps pulsewidths, which are as short as those of plain mode locking without Q switching. Similar self-Q-switching behavior is also produced by positive detunings, but the stability is very poor
