“…A comparison of performance of the diode-pumped Yblasers in the sub-100 fs regime is shown in Figure 3. As can be seen, the generated 56 fs pulses with 450 kW of peak power in our work demonstrate more than one order of magnitude higher average and peak powers when compared to the previous sub-60 fs diode-pumped Yb-lasers [37][38][39][40][41][42]. We believe that such a powerful ultrashort pulse laser source will be attractive for nonlinear frequency conversion into the visible and near-infrared ranges [43][44][45].…”

A high power sub-60 fs mode-locked diodepumped Yb:KGW laser based on hybrid action of an InGaAs quantum-dot saturable absorber mirror and Kerr-lens mode locking was demonstrated. The laser delivered a 56 fs pulse with 1.95 W of average power corresponding 450 kW of peak power. The width of the generated laser spectrum was 20.5 nm, which was near the gain bandwidth limit of the Yb:KGW crystal. To the best of our knowledge, these are the shortest pulses generated from the monoclinic double tungstate crystals (and Yb:KGW laser crystal in particular) and the most powerful in the sub-60 fs regime. At the same time, they are also the shortest pulses produced to date with the help of a quantum-dot-based saturable absorber. High power operation with a pulse duration of 90 fs and 2.85 W of average output power was also demonstrated.

“…In addition, the large lower-level splitting results in a broad emission bandwidth, which is beneficial to generate ultrashort pulses by various mode-locking techniques. Until now, a number of Yb 3+ -doped laser materials have been developed to generate femtosecond pulses [3][4][5][6][7]. The shortest pulse duration reported thus far was 32 fs in a Yb:CaGdAlO4 oscillator optically pumped by a fiber laser [8].…”

Abstract:We demonstrate the first Kerr-lens mode-locked operation in a diode-pumped Yb:GdYSiO5 oscillator. Under a diode pump power of 5 W, 141 fs pulses with an average power of 237 mW were obtained at a repetition rate of 118 MHz. The central wavelength was at 1094 nm with a bandwidth of 10.1 nm. Shorter pulses were obtained by adjusting the cavity to operate at a shorter wavelength, resulting in 55 fs pulse duration at the central wavelength of 1054 nm with a bandwidth of 23.5 nm.

“…During the past few decades, the trivalent ytterbium (Yb 3+ ) ion has been recognized as one of the most important doping ions for diode-pumped lasers, especially in the ultrashort pulse laser fields [1][2][3][4]. The simple electronic energy levels of Yb 3+ ion are beneficial to eliminate the undesired effects, such as up-conversion, excitedstate absorption, cross-relaxation process and concentration quenching.…”
