Characterization of Diode Laser-Pumped Nd:YVO4 Disk Laser

Abstract

In this work describe experimental set up disk laser of Nd:YVO4 in active mirror configuration, face pumping and cooling by thermoelectric Cooler (TEC) type heat exchanger to over come the limitation of prior design. With (4x5x1mm) disk dimensions to investigate the relationship between the pumping power from a diode laser at (808nm) with the optical elements in the setup and with the output power. The results show that a (0-600)mW CW output power which indicate 56% efficiency at (1064nm) wavelength from Nd:YVO4 thin disk material when pumped with power between (0-1500) mW from a 808nm CW laser diode.
