Wavelength tunable graphene modelocked VECSEL

We passively modelock an optically pumped VECSEL by using a single-layer graphene saturable absorber mirror, resulting in pulses as short as 473 fs. A broad wavelength tuning range of 46 nm is achieved with three different VECSEL chips, with a single chip 21 nm are covered.
