A resonator configuration is proposed in which HR mirror is used in a folded configuration employing a Corner cube prism. Variable output is obtained by rotation of Quarter wave Plate. Two Resonator configurations are presented. Round trip Jones Matrix is calculated & loss factor is plotted against angle of rotation of Quarter wave plate for both configurations. Nd:YAG laser built in configuration 1 is described. Effect of rotation of corner cube prism on the loss factor & effect of misalignment of HR mirror on output energy is investigated.
