Abstract : A simple, reliable technique is described for frequency stabilizing a CW-TEA hybrid laser for use as a transmitter in a laser radar system with heterodyne detection. In this technique, modulation is applied to the laser cavity, the output frequency of the laser is monitored when operating in the CW mode, and the TEA laser discharge is triggered when the desired output laser frequency is detected. Details are given of the electronics used to implement the technique, as well as those for controlling the pulse repetition rate and protecting the laser itself if arcs are generated in laser discharge.
