| Abstract: | Conclusion The optimum wavelength of Nd3+-doped double-clad fiber laser or amplifier made in China is near 830 nm. The efficiency of Nd3+-doped double-clad fiber devices pumped by 820-nm laser is low due to ESA. In order to increase the photochemical stability of the outer cladding, the material of the outer cladding must be advanced. |
| Keywords: | double-clad fiber optimum pump wavelength optical spectrum |
