Abstract:
1. A method for achieving desired output power turn-on time while maintaining optimal efficiency for a WBC laser system, the method comprising: measuring the output power and turn-on time of a plurality of diode elements versus lasing wavelength, versus output coupler reflectivity, versus simmer current, and versus operating current or power; determining an optimal output coupler reflectivity; determining an optimal simmer current; determining an optimal operating current or power; determining an optimal band region for each diode element; determining an optimal placement within an array of multiple diode elements and converging onto a common dispersive element, wherein the optimal placement of each diode element within the array of diode elements is based on the optimal band region for each diode element; and providing a partially reflective output coupler configured to receive an output beam from the dispersive element, the partially reflective output coupler configured to provide feedback to each of the plurality of diode elements and thus provide unique wavelength stabilization, the output coupler also being configured to transmit a single combined wavelength beam.
