Abstract
A laser apparatus comprises a pump laser device, and a polarizing optical fiber having a proximal end and a distal end, with the polarizing optical fiber coupled to the pump laser device at the proximal end. At least one output reflector is written on the polarizing optical fiber toward the distal end. Only one polarization mode is supported when a laser beam is transmitted through the polarizing optical fiber from the pump laser device.
