Abstract: | A theoretical model for longitudinally pumped quasi-three-level lasers under Q-switched, repetitively Q-switched, and cw operating conditions is developed. The model is applied using 8% Ho:YAG as the gain medium, and it is found that for typical conditions the effective energy storage time can be much less than the upper state lifetime, in agreement with experiment but not predicted by earlier theories. This effect is attributed to details of laser design and pumping conditions, as opposed to being an intrinsic property of the gain material |
