Laser degradation is usually reported to occur on the facet mirrors; however, inner cavity degradation also occurs. To improve the understanding of the degradation mechanisms local spectroscopic techniques are necessary. Spectrum imaging cathodolumin

High temperature (140 °C) and high current density (17 kA cm − 2 ) aging tests have been applied to InGaAs/AlGaAs 980 nm single-mode pump lasers. The use of low reflectivity ( 1%, AR) coatings on both facets leads to a symmetrical cavity configura

It is reported on the passivation of the mirror facets, opened in the air, of ridge waveguide InGaAs/GaAs/AlGaAs single quantum well (λ=980 nm) laser diodes. The passivation concept consists of two steps, namely, oxide removal by irradiation of the

We demonstrate record kink-free output powers, over 1.2 W, for 1060-nm single-mode lasers. Saturation powers of 1.9 W are observed at room temperature that guarantee high-power and kink margins with respect to typical operation conditions.

We have demonstrated a saturated output power of +26 dBm with a cladding-pumped Yb-free erbium-doped fiber amplifier owing to the matching of the multimode pumps wavelength with the erbium absorption spectrum. These results corresponded to saturated
