2022-11-28 A dataset of LD end-pumped Er,Pr:GYSGG single crystal fiber laser as a potential mid-infrared seed source applied in radiation environment doi:10.57760/sciencedb.04687 en We demonstrate the influence of gamma-ray irradiation on the propagation loss and laser performance of an Er,Pr:GYSGG single crystal fiber (SCF). The size of SCF is f 0.75 mm×70 mm and the diameter fluctuation is less than 3.5%. The propagation loss coefficients of the samples are 0.07 and 0.09 dB cm-1 before and after irradiation, respectively, which is almost unaffected. The maximum output powers of 197 and 192 mW on the SCFs before and after irradiation are obtained under a 969 nm laser diode (LD) end-pumping, corresponding to the slope efficiencies of 8.1% and 7.9%, respectively. A very good beam quality factor Mx2/My2 of 1.11/1.13 is achieved. These results imply that the Er,Pr:GYSGG SCF laser can be used as a potential seed source for mid-infrared (MIR) multi-stage amplification laser apparatus applied in radiation environment.
