1µm saturable absorber with recovery time reduced by lattice mismatch
Appl. Phys. Lett. , Volume 89 - Issue Article number: 71112 p. 1- 3
Metamorphic growth of lattice mismatched InGaP on GaAs has been used to fabricate a fast semiconductor saturable absorber mirror operating at the 1060 nm wavelength range. The absorption recovery time could be reduced to ~5 ps without deteriorating the nonlinear absorption properties. The device was used to demonstrate self-starting operation of a mode-locked Yb-doped fiber laser and obtain high quality picosecond pulses.
