The fluorescence evolution along Tm3+-doped ZrF4–BaF2–LaF3–AlF3–NaF (ZBLAN) optical fibers, as well as amplified spontaneous emission in the UV-IR region with emphasis on 350 nm, 365 nm, and 450 nm, is studied, estimating optimal fiber length

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 here the efficiency improvement in a fiber Raman laser by splicing to it short pieces of 10000-ppm Yb3+-doped fibers. The amplified spontaneous emission produced by the doped fiber started the stimulated Raman scattering earlier than the sp

In this work, we report 1064 nm laser emission in Nd:YVO4 channel waveguides fabricated by carbon implantation. Typical threshold pump powers (∼808 nm) were ≥45 mW. Maximum conversion efficiency was 11.5% (29.6% slope efficiency), and up to 9 mW

Ti:sapphire lasers are widely used in many applications in optics; the designs of three-and four-mirror resonators are the basic configurations for these systems. In this work, we analyze the advantages and disadvantages of each configuration. The ai

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 Tm3+-doped fluorozirconate (ZBLAN) fibre laser operating CW at 806 nm when diode-pumped at 687 nm is described for the first time. This device is based on the 3F4 → 3H6 transition, and is suitable for first telecom window and sensing applications

The critical power level provides an objective tool for the determination of the maximum power available in a fiber laser based on physical parameters such as core diameter, temperature, and absorption and emission cross section for both the pump and
