Paper Abstract

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 research, we present a theoretical analysis of solid-state Ti:sapphire femtosecond lasers. In our studies on the dynamics of self-mode-locked Ti:sapphire femtosecond lasers we used the analysis method of quantum theory. We have established a quantum mode-locked equation which describes the pulse shaping mechanism of Ti:sapphire lasers. Number density and the average value of the pulse field are obtained in a Schrodinger picture. After transforming the quantum mode-locked equation into a classical equation, we analyzed the gain medium characteristic, and we 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.
