| Abstract: | Relationship among lasing wavelength, fiber length and dopant concentration has been deduced in Yb 3 doped fiber laser. Based on the relationship, a single spatial mode ring fiber laser operating at 1053 nm pumped by a 981.5 nm, laser diode has been achieved with a linewidth of 5 nm, pumping threshold 1.85 mW and slope efficiency 3%. |
| Keywords: | doped fiber laser Yb doping LD pump ring cavity |
