摘要
固体激光器中热效应引起的波前畸变影响了高光束质量、高功率的激光输出,限制了它在当代工业加工和科学研究领域的应用发展。以激光波前畸变的产生机理和传导冷却端面抽运板条激光器的优势为切入点,利用哈特曼-夏克(H-S)波前探测器进行一系列的波前畸变测试。通过对静态波前畸变量、输出功率百瓦量级时的波前畸变量和输出功率千瓦量级的波前畸变量等结果进行数据分析,对实验进行反馈,提出改进意见,以期望进一步减少传导冷却端面抽运板条激光放大器的热效应。
High power and good beam quality of solid laser has potential applications in modern industrial processing and scientific research, while the parameters of laser are affected by the dynamic thermal distortion caused by the thermal effect in solid state laser. Taking wave front distortion of the laser and advantage of the conduction cooled end-pumped slab （CCEPS） as a starting point, the wave front distortion caused by thermal effect in the CCEPS is measured by use of Hartmann-Shack wave front detector. By the analysis of results in the measurements of the aberration in the CCEPS, when the output power is different, the dynamic thermal distortion is obtained.
