The effects of TGG crystal length on output power of end-pumped unidirectional ring vanadate laser
Abstract:   (822 Views)

In this article, the effects of TGG crystal length on optimization and operation of unidirectional ring vanadate laser have been considered. For this purpose, with numerical analysis of thermal lensing of TGG crystal and considering it as a thin lens in the resonator, the optimization for different lengths of TGG crystal have been done. We obtained that for Optimum Performance, the longer crystals should have shorter resonator and the obtained optimal pump power should be lower than the shorter crystals. Then, experimental results were compared with theoretical results and they were in a good agreement. Finally, for all three crystals, output power and laser efficiency were about 5.5 W and 20% respectively.

Keywords: terbium gallium garnet, faraday rotator, optical diode, thermal lensing, unidirectional ring laser
