MOPA结构脉冲光纤激光器输出特性的实验研究
Experimental Study of MOPA Structure Pulse Fiber Laser
摘要
Abstract
A two-stage optical amplification system is constructed by using double-clad Yb-doped fiber as the gain medium and multi-mode continuous pumped laser diode as the pump source.The circuit-direct modulated semiconductor laser is used as seed source to develop Master-Oscillator Power-Amplified (MOPA)fiberized pulsed fiber lasers.The output power character-istics of the fiber laser and gain characteristics of the secondary amplifier under different pulse width and repetition frequency are studied experimentally.A pulsed laser output with central wavelength of 1.06μm,peak power of 10.4 kW and maximum average power of 21 .3 W is obtained by adj usting the seed source under the condition that the primary pumped power is 2 W and secondary pumped power is 31 W.The maximum gain can reach 16.7 dB at 900 kHz repetition frequency.The experimen-tal results show that the pulse width and repetition frequency are positively correlated with the laser output power.At high rep-etition frequency,the gain characteristics of optical amplifier are positively correlated with the pulse width.关键词
