Once reached the threshold for operation, Raman fiber lasers with high output couplers convert the pump signal into stokes signals very efficiently. However, high threshold implies lower overall efficiency and hence the ratio slope efficiency-to-thre

We report a single-mode, highly stable, continuous-wave Ho3+: ZBLAN fiber laser. The system was pumped by a 1175-nm fiber Raman laser and emitted at ∼2950 nm. The optical-to-optical conversion efficiency was 43% that is the highest reported in the

A simple experimental configuration for measurement of the Raman gain coefficient is demonstrated. The Raman threshold condition plays a role important to calculate the critical power and the Raman gain coefficient. Analysis of the Raman threshold fo

This paper presents a theoretical and experimental study on the behavior of the Raman gain efficiency for any Stokes and excitation wavelength. Analyzing the Raman threshold for two adjacent Stokes we find a mathematical relationship to the Raman gai

We report laser oscillation at 481 nm when pumping a Tm3+-doped fluorozirconate fiber by two Raman-generated signals at 1117 and 1175 nm. A superior efficiency was achieved when pumping with both lines. For example, the conversion efficiency was 20%
