Abstract

Self-starting pulses as short as 10 fs are demonstrated using a broadband semiconductor saturable absorber mirror (SESAM) to start Kerr lens mode-locking (KLM). The pulse width of these pulses is limited by the remaining third-order dispersion (TOD) in the laser cavity and the spectral bandwidth of the laser optics. The TOD of the prism controlled Ti:sapphire laser is mainly caused by the prism pair. However, the advantage of using prisms in a laser is that they allow a fine adjustment of the necessary negative group delay dispersion (GDD). This was resolved by balancing the negative TOD of the prism pair by incorporating a chirped and a double chirped mirror in the laser cavity.
