MECHANICAL Q-SWITCH (QUALITY SWITCH) FOR PULSE LASERS WITH COMMUTATOR FUNCTION Russian patent published in 2014 - IPC H01S3/125 G02B26/00 

FIELD: electricity.

SUBSTANCE: mechanical Q-switch (quality switch) for pulse lasers with a commutator function is a device with an optical-mechanical unit, a power supply unit and a processor control unit and a prefabricated prism which is installed on the rotating rotor of an electric motor; the prism consists of two rectangular prisms Ap90 fixed by their hypotenuse edges at the tiled edges of the rhomb-prism with a gap between edges. The device ensures Q-factor of the pulse laser circuit at the moment of radiation in two directions due to applied semitransparent coatings at cathetus edges of the prisms Ap90 fixed at the rhomb-prism with a nontransmitting mirror included into the laser design; at the moment of radiation the laser does not generate flare to sensors receiving the echo signal from each of two potential directions, it is ensured by a rotary shutter fixed at the rotor of the electric motor, which covers the sensors at the moment of the laser radiation and passes the received echo signal to the receiving sensors due to two cuts made in its edge.

EFFECT: reducing weight and dimensions of the device.
