Keywords:mode-locked lasers, chirped mirror, ultra-short pulse lasers

We have developed Kerr-lens mode-locked Tm:Sc2O3 laser. In this research, we introduced chirped mirror for dispersion compensation and changed OC transmission from 1% to 0.5% to obtain shorter pulse. We obtained mode-locking operation with spectral bandwidth of 26nm and an average power of 300mW.
