“…In 2017, Xu et al [24] of Jiangsu Normal University reported for the first time a novel Tm:LuScO 3 mixed sesquioxide ceramic laser operating in a passively Q-switched regime using SWCNTs as a saturable absorber. In 2019, Stevenson et al [25] realized 240 fs mode-locked operation of a Tm:LuScO 3 laser with SESAMs. Recently, a Tm:LuYO 3 ceramic laser operating in continuous-wave (CW) and passively Q-switching regimes was reported.…”

A direct Kerr-lens mode-locked Tm: LuYO3 ceramics laser without the aid of any mode-locked starting element is reported for the first time. The pulse duration as short as 259 fs and maximum average output power of 326 mW are obtained at a repetition rate of 97.1 MHz. The corresponding optical spectrum centered at 2053 nm exhibits a bandwidth of 19.8 nm, which indicates the presence of nearly Fourier transform-limited pulses. Such a Kerr-lens mode-locked Tm: LuYO3 ceramics laser is a promising ultrashort pulse source, with both the excellent laser characteristics of Tm: LuYO3 and the high-power 790 nm LD pumping scheme.

“…Tm 3+ -doped 'mixed' sesquioxides (A,B) 2 O 3 with compositional disorder inducing inhomogeneous broadening of the absorption and gain spectra are obviously advantageous in the sub-100-fs regime at 2 µm [9][10][11] . Compared with crystalline sesquioxides, transparent ceramics offer more flexibility owing to the less-challenging fabrication process.…”

We report on a power-scalable sub-100-fs laser in the 2-µm spectral range using a Tm 3+ -doped 'mixed' (Lu,Sc) 2 O 3 sesquioxide ceramic as an active medium. Pulses as short as 58 fs at 2076 nm with an average output power of 114 mW at a pulse repetition rate of approximately 82.9 MHz are generated by employing single-walled carbon nanotubes as a saturable absorber. A higher average power of 350 mW at 2075 nm is obtained at the expense of the pulse duration (65 fs). A maximum average power of 486 mW is achieved for a pulse duration of 98 fs and an optical conversion efficiency of 22.3%, representing the highest value ever reported from sub-100-fs mode-locked Tm lasers.
