INCLINED PUMP BEAM RADIATION EMITTER

摘要

The invention relates to a device for optical pumping radiation emission comprising light emitting means (19) provided with a first resonant cavity having a first input mirror and an output mirror, optical pumping means (21) for emitting a pumping beam of the first cavity, wherein the normal to the input face of the resonant cavity is inclined at an angle ? with respect to the propagation direction of the pumping beam (20), means for forming a second pumping beam resonant cavity, wherein said means comprises a second input mirror forming said second cavity with the output mirror of the first cavity. The inventive device is characterised in that it comprises an optical element transparent to the pumping wavelength between the first and second input mirrors.
