Continuous-wave Ho:GdVO4 laser pumped by Tm-doped fiber laser with a fiber Bragg grating at room temperature

We reported the Ho:GdVO4 laser pumped by Tm-doped laser with a fiber Bragg grating. 2.03W continuous-wave Ho:GdVO4 laser output power is obtained under 10.5W incident pump power, with the optical-to-optical conversion efficiency and slope efficiency of 19.3% and 32.3%, respectively, at 7°C. We can s...

Description
Summary:We reported the Ho:GdVO4 laser pumped by Tm-doped laser with a fiber Bragg grating. 2.03W continuous-wave Ho:GdVO4 laser output power is obtained under 10.5W incident pump power, with the optical-to-optical conversion efficiency and slope efficiency of 19.3% and 32.3%, respectively, at 7°C. We can see that, the lower the temperature is, the better the laser output character is. The beam quality factor is M2∼1.29 measured by the traveling knife-edge method.
