Effect of Back-cavity Mirror on Output Characteristics of Yb3+-Doped Double-clad Fiber Laser
|
Abstract:
The Yb3+-Doped Double-Clad Fiber Laser was constructed by using Yb3+-Doped Double-Clad Fiber made in China and a set of back-cavity mirrors with different reflectivity ratios. The output power and spectrum were measured . The effect of back-cavity mirror on the output characteristics of the laser had been studied theoretically and experimentally. The relationship of the reflectivity ratio of the back-cavity mirror and the wavelength of the output laser beam had been discussed deeply. It is found that the output characteristics of the fiber laser can be better by designing the reflectivity ratio of the back-cavity mirror.
