High Power Planar Waveguide (PWG) Pump Head with Modular Components for High Power Laser Systems

摘要

The system includes a master oscillator (102), one or more laser diode pump arrays (208), a planar waveguide (PWG) pump head (204-206, 308), input optics (202), and output. And a PWG amplifier (104) having optical systems (213, 214). The PWG pump head is configured to receive a low power light beam (1102) from a master oscillator and generate a high power light beam (116). The PWG pump head includes a laser gain medium (1110), a cartridge (206), and a pump head housing (204). The cartridge is configured to receive and hold the laser gain medium and includes one or more cooling channels (1106-1108) configured to transport a coolant to cool the laser gain medium. The pump head housing is configured to receive and hold the cartridge, and the cartridge is removable from the housing.
