摘要
研究了基于Ho^(3+)/Pr^(3+)共掺AlF_(3)基玻璃单包层光纤的瓦级~3μm激光。采用单模1150 nm光纤激光器泵浦上述增益光纤,得到了波长2.87μm的激光输出,其最大输出功率为1.02 W,激光斜率效率为10.7%,输出激光的光束质量因子M2≈1.2。研究结果表明,AlF_(3)基玻璃光纤是一种潜在的可获得高功率中红外激光输出的增益介质。
A mid-infrared fiber laser operating atλ≈3μm is demonstrated using a Ho^(3+)/Pr^(3+) co-doped AlF_(3)-based glass fiber as a gain fiber.Under 1150 nm single-mode fiber laser pumping,the fixed-wavelength laser had maximum output power of 1.02 W,a slope efficiency of 10.7%,and M^(2)≈1.2.The results prove this type of fiber is a potential gain medium for more powerful mid-infrared fiber lasers.
