Analysis of passively Q-switched lasers with simultaneous mode locking

Simultaneous Q-switching and modelocking in a diode-pumped Nd:YAG/Cr/sup 4+/:YAG laser is experimentally demonstrated. A general recurrence is derived for the analysis of the temporal shape of a single Q-switched envelope with mode locked pulse trains. With the developed model, the modelocked pulse energy and the total Q-switched pulse energy can be calculated. Excellent agreement was found between the present results and detailed theoretical computations.
