Abstract:
1. A method of rapidly changing a pump source in a laser system, comprising the steps of: providing a pump cavity having a roof-top structure having a roof-top portion and an interior light scattering reflector surface, specular reflective side plates and a base opposite the top; positioning a laser rod within the roof-top portion of the roof-top structure between the specular reflective side plates within the pump cavity; providing a laser resonator output coupler and a laser resonator reflector for the laser rod; and pumping the laser rod with a first pump diode laser array with a wavelength spectrum optimized for pumping at a first operating temperature, wherein the first pump diode laser array is connected to a movable mounting structure to allow rapidly changing the first pump diode laser array with a second pump diode laser array without touching laser resonator components.
