Laser with grating feedback unstable resonator
Patent
·
OSTI ID:6258724
An unstable resonator laser is described, comprising: a gain medium, a partially reflective output coupler positioned on one side of the gain medium to partially reflect back into the gain medium and partially transmit optical radiation received from the gain medium, and a reflector positioned on the other side of the gain medium to reflect optical radiation received from the gain medium back into the gain medium. Either the output coupler or the reflector is made of a material capable of supporting an optical spatial grating, and having an optical spatial grating therein which is curved to produce unstable resonation through the gain medium in response to lasing stimulations.
