OPTOELECTRONIC AMPLIFIER Russian patent published in 2004 - IPC

FIELD: optical systems.

SUBSTANCE: the amplifier has five turned mirror-reflectors, correcting lens, optoelectronic transducer and an electro-optical modulator, the optical output of the radiation source is connected to the first optical input of the turned semi-transparent mirror-reflector, whose second optical input and the first and second optical outputs are coupled respectively: through the lens to the optical output of the second turned mirror-reflector, to the first optical input of the optically controlled transparent amplifier, and to the optical input of the third turned mirror-reflector, whose optical output is coupled to the optical input of the fourth turned mirror-reflector, whose optical output is coupled via the optoelectronic transducer to the second optical input of the mentioned optically controlled transparent amplifier, having an optical output coupled via the electrooptical modulator to the optical input of the fifth turned mirror-reflector, whose optical output is coupled to the optical input of the first turned mirror-reflector, whose optical output is coupled to the optical input of the second turned mirror-reflector.

EFFECT: enhanced gain.
