MULTICHANNEL OPTICAL RADIATION FREQUENCY STABILIZATION SYSTEM Russian patent published in 2022 - IPC H03L7/00 

FIELD: optical radiation frequency stabilization.

SUBSTANCE: invention relates to the field of optical radiation frequency stabilization. To achieve the effect, a multichannel optical radiation frequency stabilization system is proposed, containing a high-Q resonator (1), a quarter-wave plate (2), a beam-splitting polarization cube (3), a photodetector (15), an electro-optical modulator (4), a laser radiation source (6), and a reference generator. frequency (14), PID controller (7), mixer (8), phase shifter (9), reference frequency generator (14), video camera (18) with display (20). Moreover, the system includes additional and series-connected photodetector (16), a mixer (13) with an additional phase shifter (10), a PID controller (12), a laser radiation source (11), while a laser radiation source (6) and an additional source laser radiation (11) through an optical combiner (5) are connected to the input of the electro-optical modulator (4). Also, the system additionally contains optical selective elements and an additional video camera (19) with a display (21).

EFFECT: reduction in weight and size characteristics of end devices, as well as simplification of settings.
