Abstract
An acousto-optic Q-switch consisting of an acoustic transducer and an acoustic absorber affixed in opposing relationship with a portion of a laser medium having a relatively high figure of merit, M, disposed therebetween, provides an integral structural combination for the function of the laser medium and Q-switch which avoids the resonating wave power losses, and eliminates the problem of reflection and alignment encountered in laser systems employing acousto-optic Q-switching devices which are separate and spaced apart from the laser medium.
