Abstract :
External compression of ultrashort pulses from Ti:sapphire lasers has led to pulses as short as 4.5 fs at a center wavelength of 800 nm, which is less than two optical cycles. It is a challenge to generate such short pulses at high repetition rates directly from the Ti:sapphire laser which is the topic of this contribution. The main limitation in achieving this goal is the design and fabrication of the intracavity optics that provides the proper dispersion compensation and the bandwidth for such short pulses. The pulsewidth and spectral shape of pulses generated directly from the laser depends much more strongly on the quality of the dispersion compensation than for pulses obtained by external compression
