ABSTRACT:
In a passively mode-locked short pulse laser arrangement including a laser resonator to which a pump beam is supplied, a titanium-sapphire (Ti:S) laser crystal, an optical Kerr element formed by the laser crystal itself, and an aperture restricting the resonator laser beam, the aperture has an arcuate or polygonal shape for adaptation to the beam cross-section.
