Efficiency & Pulse Quality The use of DM technology allows the elimination of diffraction gratings, giving the highest efficiency and best pulse quality available from any commercial highpower ultrafast amplifier. Compactness The use of FEMTOLASERS proprietary ultra broadband oscillator as seed source (> 100 nm bandwidth) allows the replacement of a grating stretcher with the compact dispersive delay line. Innovations in prism based compression technology result in a significant reduction of the overall system size.
