“…It is found that the maximum values of σ a and σ e FL are 4.7 × 10 −21 cm 2 at 1650 nm and 5.95 × 10 −20 cm 2 at 1875 nm, respectively. The prepared core glass has higher emission cross section than that of Tm 3+ doped ZBLAN glass (2.4 × 10 −21 cm 2 ) 30 and silicate glass (3.89 × 10 −21 cm 2 ) 31 .…”

Highly Tm3+ doped optical fibers are urgently desirable for 2.0 μm compact single-frequency fiber laser and high-repetition-rate mode-locked fiber laser. Here, we systematically investigated the optical parameters, energy transfer processes and thermal properties of Tm3+ doped barium gallo-germanate (BGG) glasses. Highly Tm3+ doped BGG glass single mode (SM) fibers were fabricated by the rod-in-tube technique. The Tm3+ doping concentration reaches 7.6 × 1020 ions/cm3, being the reported highest level in Tm3+ doped BGG SM fibers. Using ultra short (1.6 cm) as-drawn highly Tm3+ doped BGG SM fiber, a single-frequency fiber laser at 1.95 μm has been demonstrated with a maximum output power of 35 mW when in-band pumped by a home-made 1568 nm fiber laser. Additionally, a multilongitudinal-mode fiber laser at 1.95 μm has also been achieved in a 10 cm long as-drawn active fiber, yielding a maximum laser output power of 165 mW and a slope efficiency of 17%. The results confirm that the as-drawn highly Tm3+ doped BGG SM fibers are promising in applications that require high gain and high power from a short piece of active optical fiber.

“…Two emission peaks are observed as follows: one from 1350 nm to 1580 nm centered at 1470 nm originating from 3 H 4 -3 F 4 transition; and another from 1580 nm to 2150 nm centered at 1800 nm originating from 3 F 4 -3 H 6 transition. Given the large stark splitting of the low laser level (the ground state level), Tm 3+ -doped glass is a quasi-threelevel system [19]. As depicted in Fig.…”

“…The lifetime of 5 I 7 gradually reduces with increasing Ho 3 þ concentration. The decreased lifetime is mainly caused by glass impurities, such as hydroxyls, which are strong quenchers of the 2 mm luminescence in Tm 3 þ -doped silicate glass [28]. The longest lifetime is 3.82 ms, which is obtained from E0.5H0.5.…”
