Then L-band fiber laser is discussed in detail. Factors that influenced the output of laser, such as resonance length, erbium-doped length are analyzed theoretically.
进而对L波段光纤激光器进行了深入的探讨，并分析了影响激光器输出的因素：谐振腔长、掺铒光纤长度，且做了相应的理论分析。
Then theoretical resonance length, small end diameter, displacement node, magnification factor, shape factor and other parameters of the amplitude amplifier pole could be determined.
确定出其理论共振长度、小端直径、位移节点、放大系数、形状因数等参数。
The limiting erosion length can be determined by the resonance condition.
再由共振条件确定出管道的极限冲刷长度。
