| Abstract: | The diode pumped intracavity SHG laser using a new type Nd: YVO 4 crystal is reported. We have compared the output characters of the new type with old type crystal Nd: YVO 4. The optical conversion efficiency of the new one is two times higher than that of the old one. The slope efficiencyis up to 31%. In addition, the output power of green light is up to 108 mW. The single longitudinal mode can be operated by decreasing the pumping power. The output power of single frequency green light is more than 10 mW. |
