提出了一种利用射频控制信号对多波长光纤激光器输出的多波长信号进行整体精密调谐的方法。通过在多波长光纤激光器腔外放置射频信号控制的单边带（SSB）调制器，实现了65个波长整体精密调谐。通过改变射频驱动信号频率，可以实现多波长整体在150 MHz～12 GHz范围内的任意调谐，最低对应1.2 pm的调谐量。且调谐步长由射频控制信号决定，可精确到1 Hz。多波长整体调谐前后，多波长间隔始终保持50 GHz不变，各波长的边模抑制比(SMSR)均可达到20 dB。

A method of using radio frequency (RF) control signal to achieve multi-wavelength fiber laser output precisely tuned is proposed. 65 wavelengths simultaneously tuned precisely is achieved by placing a RF controlling single side band (SSB) modulator outside the cavity of multi-wavelength fiber laser. The multi-wavelength output can be tuned simultaneously with a tuning step ranging from 150 MHz to 14 GHz when changing the frequency of RF signal, corresponding to 1.2 pm as a minimum tuning step. The tuning resolution is determined by the resolution of the RF wave generator, which can be as low as 1 Hz. The wavelength spacing remains 50 GHz before and after the multi-wavelength tuning. The sideband-mode suppression ratio (SMSR) of each wavelength output can reach 20 dB.
