DEFINITION

Classification: 372/9

PARTICULAR BEAM CONTROL DEVICE:

(under the class definition) Subject matter wherein means is provided for controlling some characteristic or parameter of the output beam, such as its amplitude, frequency, pulse rate, direction, etc., and wherein the control is effected prior to the beam's actual departure from the resonant cavity of the laser.
