Monolithic integrated master oscillator power amplifier

摘要

A monolithic integrated master oscillator power amplifier is provided comprising means for generating and emitting a laser beam and means for amplifying the laser beam. The amplifying means is in communication with the generating and emitting means, and the amplifying means has a region in which the laser beam can expand freely prior to being outputted from the amplifying means. The means for generating and emitting and the amplifying means are coupled to each other by means for selectively controlling the laser beam as the laser beam is communicated from the generating and emitting means to the amplifying means. The means for generating and emitting and the controlling means are in communication with means for supplying pumping current independently to each of the generating and emitting means and the controlling means.
