Theoretical and experimental study on femtosecond enhancement resonator

摘要: 飞秒激光共振增强腔在非线性光学、精密光谱学等研究领域有重要应用，尤其是近年来已成为产生高重频紫外光梳的强大工具．采用循环稳定电场方法分析了飞秒激光脉冲在共振增强腔中的增强和色散特性，给出了增强倍数与精细度的关系及共振带宽与精细度和腔内色散量的关系．实验上实现了175MHz，15fs的宽谱飞秒激光脉冲的共振增强，增强倍数约为10倍左右．

Abstract: The femtosecond enhancement resonator has important applications in the fields of nonlinear optics, precision spectroscopy, etc. In particular, it has been become a powerful tool of generating ultraviolet optical frequency comb at a high repetition rate in recent years. In this paper, we analyze the characteristics of enhancement and dispersion in the femtosecond enhancement resonator by use of the circulating stable electric field method. The relations between enhancement multiple and fineness and between, resonance bandwidth and fineness as well as intracavity dispersion are obtained. Finally, we experimentally realize the resonance enhancement of 15 fs laser from a Ti：sapphire oscillator at a repetition rate of 175 MHz. The enhanced magnification is about 10.
