Special Issue Information

Dear Colleagues,

In the past two decades, there has been a significant surge in research and development focusing on ∼1000 nm pumped Raman fiber lasers and ytterbium-doped fiber lasers due to their remarkable performance and potential applications across various research and industrial domains. These lasers operate within the emission band of Yb3+ ions embedded in glass, specifically in the wavelength range from below 1000 nm to 1200 nm. The integration of these lasers within the same laser system has been the subject of numerous investigations, capitalizing on the unique characteristics offered by each type of fiber laser.

Yb-doped fiber lasers exhibit high efficiency with low thresholds, while Raman fiber lasers have higher thresholds but demonstrate improved efficiencies once operational. The integration of both types of lasers creates a synergistic effect that enhances the overall performance of composite systems. This Special Issue aims to compile review articles, original papers, and short communications that explore novel laser configurations involving either one or both types of lasers operating together within the same cavity or in chained configurations as part of more complex integrated systems.

 The topics covered in this Special Issue include, but are not limited to:

- Ytterbium-doped fiber lasers;

- Raman fiber lasers;

- Hybrid systems: Rare Earth-doped and Raman fiber lasers.

This study delves into a comprehensive examination of an optical cavity system that integrates Raman and Yb-doped gain media, with a focus on understanding their interactions. The research implies a characterization of each gain medium within the cavity while subjecting them to diverse co-pumping conditions with the other. When the Raman-lasing cavity is co-pumped by exciting the Yb-doped section, the resulting composite laser exhibits significant threshold reductions and there is an optimal co-pumping regime that enhances energy transfer from pump to Stokes. As for the complementary cavity, where the Yb-doped gain is influenced by the co-pumped Raman gain, at moderate pump powers a light-controlling-light behavior phenomenon arises. Within this regime, the 1064 nm signal suppresses the Yb-generated 1115 nm signal, suggesting potential applications in intracavity optical modulation. For higher pump levels, a cooperative effect emerges whereby both lasers mutually enhance each other. Minor variations in the primary 974 nm pump power, even by just a few milliwatts, result in significant capabilities for switching or modulating the Stokes signal. Under these conditions of mutual enhancement, the hybrid optical system validates notable improvements regarding energy transfer efficiency and threshold reduction. This research provides valuable insights into the intricate dynamics of optical cavity systems and reveals promising avenues for applications in advanced optical modulation technologies. Full article

In this paper, the development of a high-power continuous wave (CW) fiber laser near 980 nm is reviewed. This review is focused primary on the power evolution resulting from the designation of Yb-doped fibers, which is important in the suppression of the amplified spontaneous emission (ASE) around 1030 nm. Current studies on the in-band ASE as the power limitation of the Yb-doped fiber lasers near 980 nm are also summarized in this review. Full article
