Studies on the Output Characteristics of Erbium-doped Fiber Laser
掺铒光纤激光器输出特性的研究

According to the rate equations applicable to the erbium-doped fiber laser,continuous erbium-doped fiber laser of linear cavity was studied,and the expressions on erbium-doped fiber laser pumped by 980 nm band under stable condition was achieved. Variation of population density of the upper and lower levels, pump power, pump threshold and slope efficiency along a length of erbium-doped fiber were analyzed using numerical model,the experimental study on erbium-doped fiber laser by 980 nm band was shown that the pump threshold is consistent with theoretical calculate.
