摘要
介绍了一种采用导光管耦合的钕玻璃多程行波放大结构。在分析导光管结构参数与耦合效率关系的基础上,设计了包含8个激光二极管阵列的抽运结构,并模拟了输出情况。该抽运结构将168个bar条发出的抽运光会聚在8mm×8mm的范围内,获得7.3J的能量输出。根据该抽运结构的输出特性,设计了以钕玻璃作为工作物质的旋转多程行波端面抽运放大结构,并在信号光注入能量为300μJ时实现了能量为15mJ的放大输出。
A multi-pass traveling-wave Nd： glass amplifier with a duct for coupling is introduced. Based on the analysis results of the relations between structural parameters and coupling efficiency of dust, a pumping structure contains 8 laser diode arrays is designed, and it＇s output status is simulated. The pumping structure converges pumping energy generated from 168 bars on the area of 8 mm×8 mm, and about 7.3 J output energy is obtained. According to the output characters of the pumping structure, a rotated multi-pass traveling-wave amplification structure is designed, which based on the working material of Nd： glass, and 15 mJ output energy is obtained with a 300μJ injected signal laser.
