Outline of Final Research Achievements

We have developed a high power highly efficient Kerr-lens mode-locked Tm doped sesquioxides laser in-band pumped by 1610 nm high power fiber laser. To our knowledge, this is the first report of the Kerr-lens mode-locked solid state laser at the wavelength range of 2μm. The pulses as short as 115 fs and the average power as high as 1 W were achieved. Comparison with prior mode-locked 2 μm solid state laser works, it has the third shortest pulse duration and an order higher average power.
