摘要:
光谱灵活可调的高功率光纤激光在光谱合束、光声光谱检测和非线性频率变换等方面具有独特优势,近年来受到国内外研究人员的广泛关注。基于光谱灵活可调的超荧光光纤种子源,通过主振荡功率放大器结构实现了光谱中心波长1065~1085 nm可调谐、3 dB线宽2.4~13.8 nm可调谐的3 kW光纤激光输出。
Abstract:Due to the great application potential in various fields such as spectral beam combination, photoacoustic spectroscopy and nonlinear frequency conversion, high-power spectrum-tunable fiber lasers have gained much attention in recent years. Based on a spectrum-flexible superfluorescent fiber source and the well-known master-oscillator power amplifier structure, we have demonstrated a 3 kW linewidth- and wavelength-tunable high-power fiber laser. The output central wavelength of the fiber laser can be tuned over 1065−1085 nm, and the 3 dB linewidth is adjustable over 2.4−13.8 nm.
