Effect of Active Medium Temperature on the Output Characteristics of Pulsed Free-Running R6G and RB Dye Laser

Abstract

In this work, the effect of active medium temperature on output characteristics of a pulsed dye laser was studied. Two dyes, R6G and RB, were used as laser active medium. Under free-running operation, 35mJ maximum output energy and 100Ps pulse duration were obtained with presence of oxygen as a quencher. Results presented in this work showed that output characteristics such as laser pulse energy, emission linewidth, beam divergence and overall efficiency are reasonably affected by temperature. Optimum values of such features requires system to operate at temperature of 10°C which represents the optimum operating temperature. These results may benefit to determine the optimum operating temperature of a pulsed dye laser due to system design considerations.
