Thulium-doped silica fibers with enhanced 3H4 level lifetime for fiber lasers and amplifiers
Original language description
Thulium-doped fibers are renowned for their applications in high power fiber lasers at around 2 ?m. It is despite the low quantum conversion efficiency of 3F4 level in thulium doped silica fibers, which is about 10% compared to 100% quantum conversion efficiency of the ytterbium- and erbium-doped fibers, at around 1 ?m and 1.5 ?m, respectively. The lower quantum conversion efficiency increases the 2 ?m laser threshold but has almost no effect on the laser slope efficiency. Indeed, kW-class thulium-dopedfiber lasers have been demonstrated recently. Quantum conversion efficiency of the 3H4 level in non-modified silica fibers is much lower than that of 3F4 level, only about 2% and therefore most of the applications of laser transitions originating from 3H4 level are hindered by the lack of reliable low-phonon fiber host. We review of our contributions towards the comprehension and improvement of the spectroscopic properties of thulium ions doped into silica. We show potential of the deve
