Abstract: | The study of transient behaviour of a pulse pumped solid state laser system has assumed importance on account of SLM generation
by self-seeding with the pre-lase signal. This paper reports on the observations of seed pulses for two different Nd: YAG
laser rods, one with anti-reflection coating (AR) on end faces and the other without. The latter displays single longitudinal
mode behaviour in each of the relaxation pulse train while the former displays multimode behaviour. Our observations are well
explained by the ‘active etalon concept’ introduced earlier. |
