高功率、高能量、波长可调谐中红外脉冲光纤激光源在生物医疗、材料加工、红外对抗等领域具有重要的应用前景,成为目前国内外研究的热点。高功率、高能量脉冲输出可采用主动或被动调Q方法实现。与主动调Q方法相比,被动调Q方法结构简单、价格低廉,在实际应用中更受青睐。2016年,电子科技大学谢记涛等将半导体可饱和吸收镜(SESAM)被动调Q掺Er3+氟化物光纤激光作为种子,通过一级主振荡功率放大器将信号放
High-power, high-energy, tunable-wavelength pulsed fiber laser source has an important application prospect in the field of biomedicine, material processing, infrared countermeasure and so on. It has become a hot spot in the world at present. High-power, high-energy pulse output can be active or passive Q method to achieve. Compared with the active Q-adjusting method, the passive Q-adjusting method is simple in structure and low in price, and is more favored in practical applications. In 2016, Xie Jitao, University of Electronic Science and Technology of China, etched the semiconductor saturable absorption mirror (SESAM) passively Q-doped Er3 + fluoride fiber laser as a seed and passed a primary oscillator power amplifier
