Abstract :
We discuss a new low loss semiconductor structure for femtosecond intracavity mode-locking in low-gain solid state lasers. This monolithic device can be engineered to exhibit specific saturation characteristics desirable for modelocking solid state lasers. Self-starting 100 fs pulses are obtained in a diode-pumped Cr:LiSAF laser. We discuss modelocking mechanisms in quantum well passively modelocked solid state lasers, and extensions to other wavelengths
