MULTI-CHANNEL ELECTRO-OPTICAL MODULATOR (VERSIONS) Russian patent published in 2017 - IPC H01S3/107 G02F1/03 

FIELD: physics.

SUBSTANCE: multi-channel electro-optical modulator consists of a Pockels cell and several independent high-voltage generators connected to it, forming bell-shaped high-voltage pulses with a controlled amplitude up to a quarter-wave voltage and lasting less than the period of the bypass of the regenerative amplifier resonator. The Pockels cell is located in the cavity of the regenerative amplifier between the polarizer and one of the end mirrors of the resonator. The application of each high-voltage pulse to the Pockels cell leads to the fact that as the amplified laser pulse passes through the Pockels cell, its linear polarization is transformed into an elliptical one, the linear polarization component of which, perpendicular to the original, is derived from the resonator through the polarizer and thus releases some of the laser pulse energy from the resonator, and the remaining part is stored in the resonator.

EFFECT: ensuring the possibility of a laser energy phased release from the resonator and the formation of a group of pulses with arbitrary shape envelopes spaced apart from each other for a time equal to or a multiple of the period of the resonator bypass at the output of the regenerative amplifier.
