Resonantly pumped actively mode-locked Ho:YAG ceramic laser at 21221  nm

Abstract: We discuss what we believe is the first continuous-wave mode-locked Ho:YAG ceramic laser. We produced a mode-locked pulse using an acousto-optic modulator. We used a 1.91 μm Tm-fiber laser as the pump source. At the incident pump power of 11.4 W, we achieved the maximum output power of 1.84 W at 2122.1 nm in a continuous-wave mode-locked regime. We obtained a short-duration pulse of 241.5 ps at a repetition frequency of 82.15 MHz and achieved the beam quality factor M² of 1.2. In addition, the maximum single p… Show more

“…12 Active mode-locked operation of a Ho:YAG ceramic laser has also been investigated, generating pulses of 241.5-ps duration at a repetition rate of 82.15 MHz. 13 The gain-switching technique is an alternative approach for stable laser pulse generation with extreme flexibility in pulse repetition rate (PRR) control. In a gain-switched laser, pulsed operation is realized by employing a periodically modulated pump source in which the pump pulse duration and/or power amplitude is adjusted to select only the first spike in a sequence of relaxation oscillations.…”

“…While bulk solid-state lasers can provide picosecond pulse durations (<50 ps) at highrepetition-rates, they offer low average powers, as can be seen in Fig. 6.1, where the energy pulse of the previously reported works are represented as a function of their repetition rate [82][83][84][85][86][87]. On the other hand, most of the reported fiber lasers operate at low repetition rates (<50 MHz), and also provide low average powers.…”
