Abstract :
Summary form only given. The idea of using an energy limiting process such as two photon absorption to increase the pulse duration of Q-switched lasers is not recent. We demonstrate that by using this idea it is possible to achieve pulse stretching on the order of microseconds in a Q-switched alexandrite laser (750 nm) using ZnSe as the two photon absorber.
