Abstract
A laser or laser amplifier apparatus has a diode pump source producing a polarized pump beam. A laser head includes a gain medium that produces an output beam. One or more optical fibers are coupled to the diode pump source and deliver the pump beam to the laser head. A depolarization device is coupled to the diode pump source, laser head or optical fiber and produces an depolarized pump beam. By depolarizing the output beam, movement, including rotation, of the pump source does not comprise the output beam produced from the laser head.
