A dual-wavelength mode-locked semiconductor
vertical-external-cavity-surface-emitting laser is demonstrated.
A semiconductor saturable absorber mirror allows for simultaneous
mode locking of pulses centered at two center wavelengths
with variable frequency spacing. The difference-frequency control
is achieved with an intracavity etalon. Changing the finesse of
the etalon enables the adjustment of the pulse duration between
6 and 35 ps. The emitted two-color pulses are modulated by a
beat frequency in the terahertz range. Self-starting mode-locking
with 0.8-W average output power is demonstrated.
