摘要

摘要: 高功率光纤激光器通常采用如水冷散热方式进行控温，难以满足轻量化等的需求。而利用相变储能材料的特性，采用多相变控温技术，可大幅减小高功率光纤激光器系统的体积、重量。对光纤激光器的温控技术进行了分析，采用多相变温控技术，实现了波长1.08 μm、最大功率1.26 kW的全光纤激光输出，光-光效率75.4%，光束质量因子M_x²=1.21，M_y²=1.23，有效减小了激光器的体积和质量，为高功率光纤激光器的热管理提供了新方法。

Abstract: High-power fiber lasers usually use water-cooled heat dissipation methods for temperature control, which are difficult to meet the needs of light. By using the characteristics of phase change energy storage materials and multi-phase change temperature control technology, the volume and weight of high-power fiber laser systems can be greatly reduced. In this paper, the temperature control technology of the fiber laser is analyzed, and the multi-phase change temperature control technology is used. The all-fiber laser output with a wavelength of 1.08 μm and a maximum power of 1.26 kW is achieved. The light-light efficiency is 75.4%, and the beam quality is M_x²=1.21, M_y²=1.23. The volume and weight of the laser is effectively reduced. It provides a new method for thermal management of high-power fiber lasers.
