%X A stable fiber laser operating at approximately 976 nm peak power at a 280 ns and 1.9 W pump was used as a pumping source for an upconversion laser based on an Er 3+ :doped LiLuF4 crystal. A 548 nm wavelength and 320 mW could be achieved. In this study, we used a 976 nm low threshold average pump power fiber laser at 8 mW, which can achieve green upconversion laser output at room temperature. This system includes a high reflective coating at 552 nm+/-10 nm on the LiLuF4 crystal and a 96% reflective mirror forming a laser cavity for the 548 nm laser. Using the laser cavity setup and 976 nm fiber laser pump, low threshold pump power green erbium upconversion lasing was achieved. The two peak wavelengths of 548 nm and 537 nm are observed and the intensity changes by changing the input to 976 nm pump power.
