“…As the fiber length increases, the slope efficiency increases because of more pump absorption in longer fiber. However, the slope efficiency in 55-cmlength fiber is smaller than that in 34 cm which is attributed to high background loss and reabsorption in longer fiber [20]. Figure 3(b) shows the bandwidth (FWHM) of ~2 μm ASE spectra of Tm 3+ -doped tellurite fibers at various power levels.…”

Abstract:We reported the ~2 μm amplified spontaneous emission (ASE) performance of highly Tm 3+ -doped (3.76 × 10 20 ions/cm 3 ) tungsten tellurite single-mode fibers. The double-cladding fiber was pumped by a commercial 792 nm laser diode without any reflectors. Broadband ASE spectra with the bandwidth (FWHM) varying from ~45 nm to ~140 nm were achieved in a fiber length of 34 cm. The maximum output power was ~34 mW, with a slope efficiency of 4.8%. The ASE beam quality factor (M 2 ) was 1.8. The dependence of output power, ASE mean wavelength, and bandwidth on the launched pump power and fiber length were discussed in detail.

“…In particular, fiber lasers based on rare-earth materials show outstanding performances in terms of efficiency and power scalability, so that they have frequently been being used as gain media for high-power laser applications [1][2][3][4][5][6][7][8][9][10]. In particular, ytterbium (~1.1 μm), neodymium (~0.9, ~1.1, and ~1.3 μm), erbium (~1.5 μm), and thulium (~2 μm) are among the most efficient gain materials used for high-power laser applications.…”

We review and discuss the recent dramatic advances in high-power laser technology and its applications to wavelength conversion. SUMMARYOver the last decade fiber laser technology has made remarkable advances in a multitude of regimes, including continuous-wave and pulsed regimes for various gain materials. In particular, fiber lasers based on rare-earth materials show outstanding performances in terms of efficiency and power scalability, so that they have frequently been being used as gain media for high-power laser applications [1-10]. In particular, ytterbium (~1.1 μm), neodymium (~0.9, ~1.1, and ~1.3 μm), erbium (~1.5 μm), and thulium (~2 μm) are among the most efficient gain materials used for high-power laser applications.

“…Key examples of this for powerscaling the 9xx nm transition are double-clad glass fibers [52], [53], crystal fibers [54], [55], or PWs [25], [56]. Ultimately, it is the combination of low-loss waveguides, high pump-irradiancelength product, and the excellent thermal management characteristics provided by the PW that has proved to be critical in power-scaling this laser transition into the 100 W regime [35].…”

In this paper, we present the underlying advantages that make the crystalline planar waveguide (PW) the key ingredient in power-scaling difficult or "weak" laser transitions, especially those which are extremely challenging to operate in other gain medium configurations. The planar waveguide architecture is shown to enable efficient laser operation of low-gain and/or quasi-four-level transitions that suffer reabsorption losses. Exemplar configurations are reported to make this case, for example, 1.4 W at 1.8 μm from a Nd:YAG double-clad planar waveguide laser (PWL), in addition to 0.5 W at 2.7 μm from a similar highly doped Er:YAG PWL. New laser performance levels from sesquioxide PWs fabricated by pulsed laser deposition are also presented for the first time, with >1 W obtained from a Yb:Y 2 O 3 PWL. Current performance and future prospects are discussed for this laser architecture.
