Abstract:
1. A temperature insensitive diode-pumped solid state laser, the laser comprising: a. a pair of reflectors for defining a laser cavity; b. a wavelength stabilized pump laser diode for emitting pump light at a pump wavelength into the laser cavity; c. a laser gain crystal disposed in the laser cavity for absorbing the pump light and for producing a laser output; d. an optical beam splitter for tapping a portion of the laser output; e. a photo detector for detecting a power of the tapped laser output and for outputting a signal representing the detected power; and f. a feedback control system for receiving the signal from the photo detector and for controlling a drive current of the pump laser diode based on the signal from the photo detector; wherein the pump wavelength of the pump laser diode is stabilized using a wavelength locking mechanism, and wherein the wavelength locking mechanism comprises a volume Bragg grating.
