我们提出并证明了一种机制，广泛调谐L波段掺铒光纤激光器与普通的商业可调谐光纤布拉格光栅。该函数是基于线性重叠激光腔中的双波长双稳态。通过以约11 ms的典型切换时间触发泵浦，激光器可以在分别位于L波段的短波长区域和长波长区域中的两个波长之间切换。这两个波长可以独立地调谐，以使激光器的总调谐范围为33 nm，输出动态范围为7 dB。在整个调谐范围内实现了几乎恒定的输出功率和高的光信噪比。
We propose and demonstrate a mechanism to widely tune L-band erbium-doped fiber lasers with ordinary commercial tunable fiber Bragg gratings. The function is based on the dual-wavelength bistability in linear overlapping laser cavities. The laser may be switched between two wavelengths located, respectively, in the short- and long-wavelength regions of the L-band by triggering the pump with a typical switching time of about 11 ms. The two wavelengths can be independently tuned to give the laser a total tuning range of 33 nm and an output dynamic range of 7 dB. Nearly constant output powers with high optical signal-to-noise ratios are achieved across the whole tuning range.
