ABSTRACT:
A solid-state laser oscillator/amplifier system, which combines in a single laser crystal the operations of a narrow beam oscillator and a large volume amplifier, utilizes the polarization feature of the laser beam to effect coupling of an amplified beam out of the resonator in a manner which efficiently utilizes the whole volume of the active medium. The system generates a high brightness laser beam with high output energy contained in a small divergence angle.
