摘要
围绕着解决环境稳定性、自启动等主要挑战,非线性环镜锁模技术的发展脉络可概括为含有偏振控制器的非全保偏结构、双增益式全保偏八字腔结构和含有相位偏置器的全保偏九字腔结构。其中新型的九字腔非线性环镜锁模光纤激光器兼具自启动性能好、环境稳定性高、结构简单、成本低廉等特点,在光学频率梳、太赫兹抽运源以及工业材料微加工等领域有着良好的应用前景。
Abstract
To improve the environmental stability and self-starting ability, researchers have developed the nonlinear optical-loop mirror and nonlinear amplifying-loop mirror (NALM) mode-locking technologies. The developing process of these technologies can be summarized as the following three phases: non-polarization-maintaining (PM) structures with polarization controllers, PM figure-of-8 cavity structures with dual-gain, and PM figure-of-9 cavity structures with a phase shifter. Among these, the newly invented figure-of-9 NALM mode-locked fiber laser is particularly advantageous owing to its easy self-starting ability, long-term stability, concise structure, and cost-effectiveness. Such a mode-locked fiber laser is increasingly employed in applications such as optical frequency combs, generation of THz radiation, and advanced material micromachining.
