Femtosecond pulse generation by a dispersion-compensated, coupled-cavity, mode-locked Ti:sapphire laser

Results are presented that illustrate how the operation of a coupled-cavity mode-locked Ti:sapphire laser depends on some of the important operating parameters. In particular, it is shown how group-velocity dispersion plays a key role in determining the duration of the mode-locked pulses. By using dispersion compensation in both the main and the control cavities, transform-limited pulses have been generated that have durations as short as 90 fs with average and peak powers of 80 mW and 10 kW, respectively.
