LD泵浦的准连续输出双包层掺镱光纤激光器
Yb3+ -doped double-clad quasi-continuous wave fiber laser pumped by laser diode
摘要
Abstract
The theoretical mode and structure composition of a fiber laser are introduced in this paper, and a double-clad Yb3+ -doped quasi-continuous wave fiber laser system is set up by using 976 nm LD as pumped source. A square wave generator circuit for the laser pulse power source is developed, which can offer a repe- tition frequency below 1 000 Hz, pulse adjustable width between 10 p,s and 50 ms and duty ratio under 50% in a pulse mode. The characteristics and energy level system of the 11 m Yb3+ doped double-clad fiber laser are researched, and its ouput characteristics are measured. The results show that the highest output power is 2.67 W at pulse width of 10 ms and repetition frequency of 50 Hz when the maximum pump power is 8. 12 W.关键词
