METHOD FOR OPTICAL INJECTION OF LASER Russian patent published in 2013 - IPC H03K3/02 H01S3/10 

FIELD: electricity.

SUBSTANCE: method for optical injection of a giant-pulsed laser consists in illumination of an active laser element with pulse emission of an optical source excited by a pulse of current with specified duration, maintained in process of injection within controlled limits, the current value through the optical source is varied within the pulse so that energy of output laser emission is maximum possible under specified limitations for maximum and minimum values of injection current and for the value of current pulse energy. The moment of laser Q-switching and nature of injection current dependence on time are determined in advance by measurement of laser output energy as time of Q-switching and injection current varies within the specified limits.

EFFECT: increased efficiency of laser injection with available limitations for value and energy of current pulse going through the optical source.
