Issue Date: | 6-Oct-2014 | Project: | National Natural Science Foundation of China (Grant Nos. 91122021, 51272254, 61205173, and 51172236). | Serial title, monograph or event: | Optics Express | Volume: | 22 | Issue: | 20 | Abstract: | We demonstrate a comparative investigation on Er,Pr:GYSGG and GYSGG/Er,Pr:GYSGG composite crystals at 2.79 μm. Simulating results show the highest temperatures are 369 K and 318 K, respectively. A maximum output power of 825 mW with slope efficiency of 19.2% and maximum laser energy of 3.65 mJ with slope efficiency of 22.7% are obtained in the GYSGG/Er,Pr:GYSGG composite crystal, which have an obvious improvement than those of Er,Pr:GYSGG crystal. The thermal focal lengths are respectively 41 and 62 mm when the pump power is 2.5 W. All these results indicate that the GYSGG/Er,Pr:GYSGG composite crystal has great advantages in reducing the influence of thermal effects and improving laser performances. | URI: | https://hdl.handle.net/10316/102611 | ISSN: | 1094-4087 | DOI: | 10.1364/OE.22.023795 | Rights: | openAccess |
