摘要:
A Compact Interdependent Optical Laser System and Method is designed for use with wavelength beam combining (WBC) systems that utilize both slow-axis and fast-axis WBC. Multiple optical elements having individual and interdependent functionality allow for the system to compact reducing the overall footprint of the system. Additional, configurations incorporating the compact system described herein allow for high-power and brightness scaling.
摘要:
A method of direct diode pumping a fiber laser includes disposing a plurality of diode lasers in a wavelength beam combining cavity for generating a wavelength beam combining laser output, and optically coupling the wavelength beam combining laser output to the gain medium of a fiber laser. The wavelength beam combining cavity may comprise a fast axis wavelength beam combining cavity. Also, the plurality of diode lasers may comprise a multidimensional array of diode lasers arranged as diode laser bars disposed in a stack and spatially interleaved or optically aligned to form an optical stack. Each of the diode lasers may produce a distinct wavelength laser beam.
