Phase-locked loop control of passive Q- switch laser

摘要

Method and the device which control the passive Q- switch laser (PQSL) which uses the Q- switch laser as a voltaged controlled oscillator (VCO) in the phase synchronous loop control circuit are disclosed. Optics you connect PQSL with the detector. The detector is connected with the input of the phase synchronous loop controller. The reference signal oscillator is connected with the reference input of the phase synchronous loop controller. Output of the phase synchronous loop controller is connected with the integrator. You connect the integrator to the expedient which controls the electric energy which is supplied to PQSL.
