“…This phenomenon resulting from the 3 F 4 lifetime is longer than that of the 1 G 4 level. The 3 F 4 lifetime is about 1.544 ms, while the 1 G 4 lifetime is 0.817 ms (Brunet et al 1999), the ratio of which agrees with the emission intensity ratio between 793 and 473 nm. In addition, the transition crosssection of 3 H 4 ?…”

“…3 H 6 , respectively. The blue emission at 473 nm involves up-conversion pumping by a three-photon process at 1064 nm (Paschootta et al 1997;Brunet et al 1999), while, the red mission at 791 nm involves up-conversion pumping by a two-photon process at 1064 nm. In addition, as seen from the up-conversion emission spectrum, we found that the intensity of the up-conversion emission located at 791 nm is much stronger than that of the blue up-conversion emission located at 473 nm, and the emission intensity ratio is 5:3.…”

Double-air-cladding Tm 3? -doped silica fiber with a large core is fabricated by stacking capillaries method. By the excitation at 1064 nm, the optical properties of this fiber doped with 0.1 mol% Tm 3? are studied. The blue and near-infrared emissions around 473 and 793 nm are experimentally observed. In addition, the up-conversion mechanism of Tm 3? in glass is investigated. The results show that the Tm 3? -doped fiber with a large core can be used as the potential optical material for the high power fiber laser which operates at the blue and near-infrared wavelengths.

“…We have developed a model to investigate the performance of dual-band lasing originating from the same transition level. The model is based on that presented in [1,9]. First, we calculate the population densities of the energy levels for the pump and lasing wavelength transitions in Tm 3+ by solving the corresponding rate equations for steady-state conditions [1,9].…”

Fiber lasers offer several advantages over bulk solid-state lasers because they can achieve both high efficiency and fair output power. Still, the use of those silica fiber lasers is limited to very few particular applications like broadband ASE source and pulsed fiber lasers. But, since non-oxide fibers open a broad wavelength range not accessible via rare-earth doped silica fiber nor semiconductor lasers, several niches should be available. In this paper, a comparative study of performances and commercial readiness of both oxide and non-oxide fiber lasers will be done. Effectively, non-oxide fiber laser developers are confronted to several fundamental (photo-induced loss) and technical challenges (splicing, moisture, handling in general).For example, the availability of the right pump laser wavelength lags behind any serious commercial applications.Fortunately, efficient up-conversion process helps access visible to UV wavelength range with commercial JR and near-JR pumps. Also, optimization and prediction of the performance must rely almost solely on experimental validation because the numerical simulation of non-oxide glass is very complex. In particular, for up-conversion lasers, one must consider and more important, know both the emission and absorption cross-sections of 5 to 10 energy levels. Nevertheless, we will review some promising applications coming from sensors system, RGB visible sources, telecommunication applications and some special LIDAR systems that can use double-clad fiber geometry for more efficient pumping and higher power output.
