Abstract
An electronically tuned, optically pumped, transition metal based, solid-state laser is disclosed. Tuning is achieved by using resonant reflecting means comprising an output mirror, a mirror located between the output mirror and the source of laser light, a polarizer located in the light path between the two mirrors, and an electronically tuned, voltage controlled, variable, liquid crystal waveplate for receiving light passing through the polarizer. The components of the resonant reflecting means are selected to have a longitudinal mode that is anti-resonant with the optical cavity of the laser.
