50-fs pulse generation directly from a colliding-pulse mode-locked Ti:sapphire laser using an antiresonant ring
Abstract:
50-fs pulses were directly generated from a colliding-pulse mode-locked Ti:sapphire laser. To achieve the collidingpulse mode locking, a miniature antiresonant ring containing an organic saturable dye jet was employed as the end mirror for the linear cavity laser. Based on measured dispersion of intracavity elements, a prism pair was implemented to control the cavity dispersion. The generated pulses have no linear chirp but do exhibit parabolic instantaneous frequency owing to third-order dispersion introduced by the prism pair.
