HOMOGENEOUS PUMP STRUCTURE OF LASER, AND DESIGN METHOD FOR STRUCTURE |
| 摘要 |
A homogeneous pump structure of laser, and a design method for the homogeneous pump structure of laser. The homogeneous pump structure of laser is used in a fiber laser or a fiber laser amplifier, and comprises a gain fiber (21). The gain fiber (21) comprises a pump light input end and a pump light output end. The pump area of the gain fiber (21) gradually decreases from the pump light input end to the pump light output end, so that a change rate between a pump light absorption capacity of each of segments, with equal lengths, of the gain fiber (21) and a pump light absorption capacity of a neighboring segment is smaller than b %, b being an empirical value. |

1. A homogeneous pump structure of a laser used in a fiber laser or a fiber laser amplifier, comprising:
a gain fiber having a pump light input end and a pump light output end, wherein a pump area of the gain fiber gradually decreases from the pump light input end to the pump light output end, such that a change rate of a pump light absorption capacity between each segment with an equal length and an adjacent segment of the gain fiber is less than b %, wherein b is an empirical value. |
