What is High efficiency and high beam quality Er:YSGG Mid-infrared continuous-wave laser about?
We demonstrated an LD end-pumped Er:YSGG mid-infrared (MIR) continuous-wave (CW) laser based on optimized LD pump wavelength with less absorption coefficient and thermal problems. A composite crystal YSGG/Er:YSGG/YSGG with a size of 3 × 3 × 14 (2 + 10 + 2) mm3 was employed, and its central part had an erbium ion doping concentration of 38 %. The maximum output power of 2.8 μm MIR laser is 2.01 W, corresponding to a slope efficiency of 28.89 %, at which the beam quality M2 of the laser is 1.19. Compared with other Er3+-doped laser, we achieved a CW MIR laser with higher efficiency and better beam quality. The results suggest that optimizing the wavelength of the pump source and adopting the crystal bonding technology could effectively improve the performance of the LD end-pumped Er:YSGG CW MIR laser.
