A Single-mode Dye Ring; Laser with Output Coupler Using Frustrated Total Internal Reflection

Abstract

Details of a dye ring laser with an output coupler of adjustable transmission based on frustrated total internal reflection are reported. The construction allows optimization of tuning range or output power. Using appropriate intracavity etalons and a Fox-Smith reflector as mode selector reliable single-mode operation was observed with peak powers of 1 kW and bandwidths of 0.03 pm
