With intracavity dispersion compensation for self-mode-locked or active mode-locking Ti:sapphire lasers, pulses as short as 56 fs can be directly produced. Using the results of recent experimental researches, the authors present a theoretical analysis of solid-state Ti:sapphire femtosecond lasers. In their studies on the dynamics of self-mode-locked Ti:sapphire femtosecond lasers they used the analysis method of quantum theory. They have established a quantum mode-locked equation which describing the pulse shaping mechanism of Ti:sapphire laser. Number density and the average value of the pulse field are obtained in Schrodinger picture. After transforming the quantum mode-locked equation into classical, they have analyzed the gain medium characteristic, and they have found that the curve of the net gain for the Ti;sapphire must have a hollow close to the output frequency. Furthermore, the pulse shaping mechanism has been examined.
