Paper Abstract

In this paper the growth and laser properties of Nd, Ce and Cr ions-co-doped yttrium aluminum garnet (Nd:Ce:Cr:YAG) crystals were reported. Nd:Ce:Cr:YAG single crystals were grown in DJL-40D model crystal growth furnace with medium frequency induction heating by Czochralski technique from iridium crucible. The influence of the doping concentration of Nd, Ce and Cr ions on the optical quality and the pulse laser performance of the crystal and the technology conditions for growing high quality crystal were also investigated. The dimension of Nd:Ce:Cr:YAG crystal boules grown is up to (Phi) 40 multiplied by 150 mm. The interference fringe of the laser rods with the dimension (Phi) 5 multiplied by 80 mm is less than 0.5/25 mm and the extinction ratio is more than 26 dB. The pulse laser properties of Nd:Ce:Cr:YAG and ND:YAG laser rods were tested comparatively. The typical pulse laser characteristics of Nd:Ce:Cr:YAG crystal are relatively lower, threshold, higher laser efficiency, and relatively higher output power, better thermal stability and smaller nature divergence angle at Q- switching operation. At the same time, the UV radiation of pump flashlamp will not lead to the reduction of laser output.
