摘要We demonstrate the thermal analysis and laser performance of a GYSGG/Cr, Er, Pr: GYSGG composite crystal. The lifetime ratio of lower and upper levels of Er3+ in Cr, Er, Pr: GYSGG crystal is further reduced due to the optimized doping concentrations. The thermal effect of composite crystal is lower than that of Cr, Er, Pr: GYSGG crystal. A maximum pulse energy 342.8 mJ operated at 5 Hz and 2.79 mu m is obtained on the composite crystal, corresponding to electrical-to-optical efficiency of 0.86% and slope efficiency of 1.08%. Under the same condition, these values on the Cr, Er, Pr: GYSGG crystal are only 315.8 mJ, 0.79% and 1.04%, respectively. Moreover, the composite crystal has also a relative high laser beam quality, exhibiting obvious advantage in reducing thermal effects and improving laser performances.
