Abstract:
1. A microlaser arrangement comprising a monolithic body including: a layer of optically pumped gain medium; a layer of saturable absorber; first and second reflectors arranged to enclose the gain medium and the saturable absorber in order to form a resonant cavity having an optical axis; a pump beam at a pump laser wavelength applied through an input of the resonant cavity and absorbed by the gain medium to produce a laser beam at a microlaser wavelength from an output of the resonant cavity; and a first heat spreader capable of selectively absorbing optical beams on the optic axis outside of the resonant cavity, the heat spreader coupled to the output of the resonant cavity and configured to substantially absorb the pump beam or the heat spreader coupled to the input of the resonant cavity and configured to substantially absorb the laser beam.
