Pulses of 27ns duration and peak power of 1.7MW for initial transmission of Q-switch 18.4% 0 T = have been obtained. We have obtained Q-switching efficiency of 77% for train of pulses of 31 and 76.2% 0 T = at the pump energy of 98J. We have also obtained the dependency of laser pulse characteristics on pump energy and initial transmission of Q-switch. We have obtained the damage threshold of this Q-switch at the pulse duration of 27ns to be13J cm2 . }, URL = {http://ijop.ir/article-1-212-en.html}, eprint = {http://ijop.ir/article-1-212-en.pdf}, journal = {International Journal of Optics and Photonics}, doi = {}, year = {2009} }
