Optical Performance of China-made Nd~(3+)-doped Ceramic Disk

The optical performances of China-made Nd∶YAG and Nd∶YSAG ceramic disks were studied.The fabrication and spectra properties of Nd∶YAG and Nd∶YSAG transparent ceramic were introduced.For Nd∶YAG ceramic disk laser,the laser output with a central wavelength of 1 064.2 nm and a Full Width Half Maximum (FWHM) of 0.89 nm was achieved.The maximum output power was 0.319W with laser threshold of 0.267 W.For the novel Nd∶YSAG ceramic laser,which has the prolonged fluorescence lifetime and can achieve high-level doping,the laser central wavelength was 1 063.8 nm ,and the FWHM was 1.6 nm.The maximum output power was 0.356W with slope efficiency of 23.2%.The results demonstrate that China-made Nd∶YSAG ceramic is suitable for short-pulse microchip laser.
