Abstract :
A stable, mode-locked Nd:YAlG laser source would be useful for low-duty-cycle, pulsed optical communications and for providing a stable source at 5320 Å by means of second harmonic generation. Several problems arise in the construction of such a source. These are due to the extreme narrowness in frequency of the mode-locked region (6-7 kHz), the presence of relaxation oscillations at the edges of this region, and the instability in envelope phase of the output pulses when using a phase modulator.
