An Unpolarised Electro-Optically Q-Switched Laser

Abstract

A novel laser design is given that uses a special polarising device to generate unpolarised Q-switched laser energy with a conventional electro- optic Pockels cell. The special polarising device, which replaces the linear polariser normally used in conventional Q-switched resonators, allows solid state lasers to operate efficiently at high repetition rates. Other features of the design include the elimination of the beam non-uniformities that normally occur at high repetition rates, the elimination of the need to bias the Pockels cell and the ability to produce, by a simple mirror realignment, a plane polarised output with high efficiency.
