The system also utilizes a side-polished fiber in a ring cavity configuration to obtain the desired pulse train. A stable dual-wavelength pulse output is obtained at 1034.7and 1039.0 nm, with a maximum pulse energy of 2.0 n J, and a shortest pulse width of 3.2 μs. The generated pulse train is stable, and has a pulse repetition rate from 31.2 to 64.5 kHz. 关 键 词：被动调Q 双波长 二氧化钛基 掺镱光纤激光器 米波段 可饱和吸收体 脉冲重复率 脉冲串
