METHOD FOR STABILIZING OPTICAL OUTPUT POWER OF FIBER LASER

A high power fiber laser system is configured with a pump including at least one laser diode module which radiates a pump light coupled into a gain medium of active fiber as a temperature rises from a relatively low temperature to a relatively high temperature. The pump operates at a uniform diode c...

description A high power fiber laser system is configured with a pump including at least one laser diode module which radiates a pump light coupled into a gain medium of active fiber as a temperature rises from a relatively low temperature to a relatively high temperature. The pump operates at a uniform diode current and configured so that while a pump output power decreases within the predetermined temperature range, absorption of the pump light in the gain medium increases so that the output of the fiber laser system remains substantially uniform.
