    Sub-100 fs mode-locked Tm:CLTGG laser
    (Washington, DC : Soc., 2021) Wang, Li; Chen, Weidong; Pan, Zhongben; Loiko, Pavel; Bae, Ji Eun; Rotermund, Fabian; Mateos, Xavier; Griebner, Uwe; Petrov, Valentin
    We report on the first sub-100 fs mode-locked laser operation of a Tm3+-doped disordered calcium lithium tantalum gallium garnet (Tm:CLTGG) crystal. Soliton mode-locking was initiated and stabilized by a transmission-type single-walled carbon nanotube saturable absorber. Pulses as short as 69 fs were achieved at a central wavelength of 2010.4 nm with an average power of 28 mW at a pulse repetition rate of ∼87.7 MHz. In the sub-100 fs regime, the maximum average output power amounted to 103 mW.

    Sub-6 optical-cycle Kerr-lens mode-locked Tm:Lu2O3 and Tm:Sc2O3 combined gain media laser at 2.1 μm
    (Washington, DC : Soc., 2021) Suzuki, Anna; Kränkel, Christian; Tokurakawa, Masaki
    We present a combined gain media Kerr-lens mode-locked laser based on a Tm:Lu2O3 ceramic and a Tm:Sc2O3 single crystal. Pulses as short as 41 fs, corresponding to less than 6 optical cycles, were obtained with an average output power of 42 mW at a wavelength of 2.1 μm and a repetition rate of 93.3 MHz. Furthermore, a maximum average power of 316 mW with a pulse duration of 73 fs was achieved.
