Abstract
A fiber laser having a ring resonance path comprises a pump light source, a Yb-doped optical fiber and a light modulation unit. The pump light source emits a pump light. The Yb-doped optical fiber is coupled with the pump light. The light modulation unit includes a grating pair, a diaphragm and two reflective elements. The grating pair is coupled with the pump light. The diaphragm includes an aperture. The light transmitted by the grating pair partially passes through the aperture and reaches one of the reflective elements to become a reflective light, and the reflective light passes through the aperture and is transmitted through the grating pair and the other reflective element to be coupled back with the ring resonance path.
