在一个21m长的线性腔中实现了可调谐的单频掺Er光纤激光器，该腔由全光纤声光移频器和可饱和吸收光栅组成。实现了稳定的单频运转，边模抑制比大于50d B，波长调谐范围大于40 nm。
A widely tunable single-frequency Er-doped fiber laser is demonstrated in a 21-m-long linear cavity incorporating all-fiber acoustooptic frequency shifters and a saturable absorption grating. Stable single-frequency operation is achieved with a sidemode suppression ratio higher than 50 dB and a wavelength tuning range greater than 40 nm.
