Abstract

Disk lasers are a promising configuration that can produce high output power with high spatial quality of radiation due to efficient heat removal from the active region. An important task in the design of disk lasers is to achieve efficient pumping with high gain uniformity across the active region. A new multipass pumping scheme is proposed. The pumping distribution in a Yb:YAG/YAG disk-shaped composite ceramic active element has been numerically simulated and experimentally investigated. It is shown that for such a scheme with 12-channel pumping, the distribution of absorbed pump power with an inhomogeneity of maximum 12.6% can be achieved at a pumping efficiency of 80%.

具有多通道和多通道泵送功能的圆盘形复合陶瓷有源元件

摘要磁盘激光器是一种很有前途的配置，由于有效区域的高效散热，它可以产生高输出功率和高空间辐射质量。设计盘形激光器的一项重要任务是实现高效泵浦，并在整个有源区实现高增益均匀性。本文提出了一种新的多通道泵浦方案。对 Yb:YAG/YAG 盘形复合陶瓷有源元件中的泵浦分布进行了数值模拟和实验研究。结果表明，对于这种 12 通道泵浦方案，在泵浦效率为 80% 的情况下，吸收泵浦功率的分布不均匀度最大可达 12.6%。
