摘要
本文提出了一种基于布里渊泵浦（BP）操纵的波长间隔可切换布里渊-拉曼随机光纤激光器（BRRFL）。所提出的波长间隔可切换布里渊-拉曼随机光纤激光器采用全开腔结构，具有双布里渊频移波长间隔的多波长输出。通过同时向腔内注入 BP 光及其一阶受激布里渊散射光，激光输出呈现出单布里渊频移的波长间隔。波长间隔切换效果可以通过控制一阶受激布里渊散射光的功率来实现。实验结果表明，多波长输出可在带宽约为 60 nm 的双布里渊频移多波长发射和 44 nm 的单布里渊频移多波长发射之间切换。这种波长间隔可切换的灵活光控随机光纤激光器应用广泛，在波分复用光通信领域具有巨大潜力。
Wavelength-interval Switchable Brillouin-Raman Random Fiber Laser through Brillouin pump manipulation
A wavelength-interval switchable Brillouin-Raman random fiber laser (BRRFL) based on Brillouin pump (BP) manipulation is proposed in this letter. The proposed wavelength-interval switchable BRRFL has a full-open cavity configuration, featuring multiwavelength output with wavelength interval of double Brillouin frequency shifts. Through simultaneously injecting the BP light and its first-order stimulated Brillouin-scattered light into the cavity, the laser output exhibits a wavelength interval of single Brillouin frequency shift. The wavelength-interval switching effect can be manipulated by controlling the power of the first-order stimulated Brillouin scattering light. The experimental results show the multiwavelength output can be switched between double Brillouin frequency shift multiwavelength emission with a broad bandwidth of approximately 60 nm and single Brillouin frequency shift multiwavelength emission of 44 nm. The flexible optically controlled random fiber laser with switchable wavelength interval makes it useful for a wide range of applications and holds significant potential in the field of wavelength-division multiplexing optical communication.
