ABSTRACT:
A regenerative laser device having remotely located optical components. A resonant cavity having a plurality of transverse modes is defined at one end by a highly reflective retrodirective member and at the other end by a retrodirective member formed of a converging lens and a highly transmissive mirror. A body of laser material is located within the resonant cavity, and there are provided means for exciting the material to create a loop gain of the device that is substantially equal to unity. A collimating lens receives light transmitted through the mirror. An energy source supplies additional energy into the resonant cavity through the collimating lens and mirror to increase the radiation, in at least one of the transverse modes, in the resonant cavity.
