Shock Excited FTIR Q-Switch.
Abstract
A new high speed high power laser Q-Switch is described together with test results in a 100 megawatt ruby laser cavity. A frustrated total internal reflector (FTIR) is pulse driven by mechanical shockwave to produce fast switch action with good depth of modulation and low cavity insertion loss. Multiple Q-switching has been achieved at 200k p.p.s. during the laser pump cycle producing better than 80 Q-switched pulses in a half millisecond. Also described is a double pulse application to interference type holography. (Author)
