Abstract
A method or apparatus for controlling the output pulse of a Q-switched laser. The intensity of laser light within the resonator of a Q-switch laser is sensed. A reference pulse related to a desired laser output pulse shape is compared with the sensed intensity. A variation signal corresponding to differences between the sensed light intensity and the reference pulse is fed to a Pockels cell or Q-switch within the resonator. The Q-switch responds to the variation signal by altering the resonator laser light polarization to maintain the Q-switch laser's output pulse in the desired shape. The reference pulse may be dynamically altered to change the shape of the output pulse.
