双模式人眼安全MOPA全光纤激光器
Dual-mode, eye-safe MOPA all-fiber laser
摘要
Abstract
An all-fiber laser which could work with either pulse or continuous wave (CW) mode is reported. Tlie configuration of laser is master-oscillator power-amplifier ( MOPA), the seeder of which is a single mode directly modulated laser diode operating in wavelength of 1 550 run, and the amplifier consists of two preamplifiers and one main amplifier. In pulse mode, the peak power of 5.1 kW and a pulse width of 1.7 ns are obtained when the repetition rate is 50 kHz and the pump power is 4 W. In CW mode, the average power of 0.5 W is obtained. By-using this laser, the pulse and the phase laser ranging can be realized simultaneously.关键词
