Dual action of quantum-dot saturable absorber and Kerr lens mode locking of a diode-pumped Yb:KGW laser was demonstrated. The laser delivered 105 fs pulses with 2.5 W of average power and >300 kW of peak power.

A high power continuous wave dual-wavelength Yb:KGW laser using a birefringent plate was demonstrated. Stable operation at 1014.6 nm and 1046.3 nm with 3.4 W of average output power was obtained.

Generation of 170 fs pulses at 750 nm from a Ker-lens mode-locked Alexandrite laser is demonstrated. We believe that these are the shortest pulses that have been produced from a mode-locked Alexandrite laser to date.

A high-power diode-pumped pure Kerr-lens mode-locked Yb:KGW laser was demonstrated. The developed laser delivered 240 fs pulses with 2.3 W of average output power at a repetition rate of 86.8 MHz, which corresponds to 110 kW of peak power and 26 nJ of pulse energy. The limiting factor to the laser operation was the appearance of a strong continuous wave (CW) component in the mode-locked laser spectrum.

A high power sub-60 fs mode-locked diode-pumped 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 56 fs pulses with 1.95 W of average power corresponding to 450 kW of peak power. The spectral bandwidth of the pulse 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.

A high-power diode-pumped pure Kerr-lens mode-locked Yb:KGW laser was demonstrated. The developed laser delivered 240 fs pulses with 2.3 W of average output power at a repetition rate of 86.8 MHz. Shorter pulses of around 120 fs with 1.2 W of average output power were also generated. The self-starting operation of the oscillator was demonstrated. The limiting factor to the laser operation was the appearance of a strong continuous wave component in the mode-locked laser spectrum.
