摘要
采用连续运转Ａｒ￣＋激光器５１４５输出波长光作为泵浦源，采取端泵浦的平凹光学谐振腔结构，用光学斩波器作为Ｑ开关，建立了掺钕单模光纤激光器的调Ｑ实验装置，对这种激光器的调Ｑ特性进行了实验研究和讨论。
This paper presents the results of experimental study of the Q-modula-tion feature of a Nd￣(3-)-doped single mode fiber laser.The system is composed of a CW Ar￣- laser at wavelength of 5145 as a pumping source,a plane-concave optical cavi-ty,a optical chopper as Q-switch inside cavity and a PIN detecto.With the system. Q-switch output power at wavelength 1. 088μm, full width of power spectrum,rela-xation..oscillation and the relationship of Q-switch feature with pumping power and chopping frequency are expermentally studied . It is useful for fiber sensor and long dis-tance fiber communication.
