提出了一种基于被动多环腔（MRC）技术的宽带可调谐单纵模（SLM）镱光纤激光器，并首次在实验上得到了证实。两个不同的短环腔插入到主环腔中，并作为宽带模式滤波器，以确保SLM振荡。采用1 m掺镱光纤作为增益介质，在100 mW泵浦功率下，实现了波长调谐范围超过60 nm的空间光调制。该激光器在60 nm的调谐范围内输出功率稳定在6 dBm，光信噪比大于53 dB。
A broadband tunable, single-longitudinal-mode (SLM) ytterbium fiber laser based on a passive multiple-ring cavity (MRC) technique is proposed and demonstrated experimentally for the first time to our knowledge. Two different short ring cavities are inserted into the main ring cavity and serve as wideband mode filters to ensure SLM oscillation. With 1-m ytterbium-doped fiber as the gain medium, the SLM operation is achieved with over 60-nm wavelength tuning range at 100-mW pump power. The laser is very stable with output power of 6 dBm and an optical signal-to-noise ratio of higher than 53 dB in all the 60-nm tuning range.
