| 摘 要： | 对连续波高功率掺镱光纤激光器(YDFL)的输出特性及影响因素进行了实验研究。结果表明,双色镜相对于光纤轴向的倾斜角对激光器阈值和输出功率有影响,当双色镜偏离光纤轴向垂直方向时,激光器阈值增大、输出功率降低;当偏离角度小于±2°时,该倾斜角对激光器阈值和输出功率的影响较小。增益光纤有效长度也影响激光器的阈值和输出功率,并决定激光器自由振荡波长,增加掺杂光纤有效增益长度,激光振荡波长向长波长方向移动。

| Abstract: | The output characteristics and their influence factors of continuous wave (CW) high power Yb3+-doped double clad fiber laser (YDCFL) are experimentally investigated. The results show that the slant angle of the dichroic mirror (DM) with respect to the fiber axes affects the threshold and the output power of the laser. The threshold increases and the output power decreases with the increase of the slant angle, however, such influences may be neglected if the slant angle is smaller than ±2°. The effective gain length of the doped fiber may also influence the threshold and the output power, and determine the lasing wavelength. The lasing wavelength shifts to longer wavelength as the effective gain length of the doped fiber increases. |
