ABSTRACT:
A laser resonant cavity employs a dye sheet Q-switch disposed to receive the output of a laser and a Cr.sup.4+ :YAG Q-switch disposed adjacent the dye sheet Q-switch. Disadvantageous aspects of either Q-switch when used alone are eliminated, resulting in higher output energy and overall efficiency. A new Q-switch employing a dye sheet sandwiched between a pair of Cr.sup.4+ :YAG plates is also disclosed.
