摘要：

Passive mode locking of a Nd:YAlO3 laser at 1.08 and 1.34-mu-m using a nonlinear mirror based on second harmonic generation is described. A single 30-degrees cut frequency-doubling LiIO3 crystal is used to mode lock both transitions, demonstrating the superiority of this mode-locking technique over that using saturable absorbers. Pulses as short as 50 ps at 1.08-mu-m and 15 ps at 1.34-mu-m are obtained. A comparative analysis of the mode-locking performance at the two wavelength is presented, indicating that the longer pulse duration at 1.08-mu-m is due to the higher gain and insufficient number of round-trips in the pulse train development.
