Harter, D J; Yeh, J J

A self injection-locked laser is described that comprises: (a) laser medium, (b) means for exciting the laser medium to emit coherent radiation, (c) first and second reflectors disposed on either side of the laser medium to reflect the coherent radiation along a first resonator path substantially perpendicular to each of the reflectors, (d) resonator-switching means disposed between the laser medium and the first reflector either to transmit the coherent radiation or to reflect the coherent radiation from the laser medium to a second resonator path, (e) means to control the resonator-switching means so that it is initially transmitting and subsequently reflecting, (f) a third reflector to reflect back toward the resonator-switching means coherent radiation incident on it along the second resonator path, the third reflector or the second being partially transmitting, and (g) loss means disposed between the resonator-switching means and first reflector sufficient to permit laser output in a single longitudinal mode from the partially-transmitting second or third reflector.
