Research output: Article


We demonstrate a versatile test method of large-aperture femtosecond mirrors inside a long-cavity Ti:sapphire laser oscillator. The Herriott-cell inside the cavity is utilized for the purpose of carrying out full-aperture testing. The method is highly sensitive to the homogeneity of mirror reflectivity and group delay dispersion over the whole mirror surface and it is suitable for testing both high reflector and chirped mirrors starting from 2" size up to arbitrarily large apertures.
