Femtosecond high-power spontaneous mode-locked operation in vertical-external cavity surface-emitting laser with gigahertz oscillation

Abstract

We realize a femtosecond high-power spontaneous mode-locked operation with gigahertz oscillation in a vertical-external cavity surface-emitting laser under the condition of eliminating the internal and external unwanted reflection. We find that the reflectivity of the output coupler has a significant influence not only on the output power but also on the output pulse duration. With an incident pump power of $20\mathrm{W}$, we have achieved $2.35\mathrm{W}$ of average output power with $778\mathrm{fs}$ pulse duration at a repetition rate of $2.17\mathrm{GHz}$. The shortest pulse duration was $654\mathrm{fs}$ at an average output power of $0.45\mathrm{W}$.
