摘要:

 通过构建基于非线性偏振旋转机理的掺Yb3+环形光纤激光器, 获得了等幅和非等幅两种双波长输出状态, 分别测量其输出功率. 结果表明, 由于不同波段激光增益的差别较大, 因此不同波长的转换效率相差较大.  分析了双波长输出的可调谐特性, 并考察了泵浦功率对1 029 nm和1 048 nm双波长输出的影响.   观察到2~7个波长的输出, 并测量了其泵浦功率区间及最大输出功率.

Abstract:

A Yb3+-doped ring fiber laser based on the principle of nonlinear polarization rotation was constructed. Two kinds of dual-wavelength output (DWO) including the equal\|amplitude and unequal-amplitude DWOs were obtained and their output powers were measured. The results show that   the laser conversion efficiencies of different wavelengths were rather different due to gain difference. The DWO tunability was also analyzed, and  the influence of pump power on DWO at 1 029 nm and 1 048 nm was investigated. The laser outputs from dual-to seven-wavelengths were observed, and the corresponding pump power ranges and the maximum output power were measured.

Key words: fiber optics, fiber laser, dual\, wavelength tunability, nonlinear polarization rotation, multi\, wavelength, Yb3+-doped fiber
