The Femtosource scientific XL Ti:sapphire oscillator provides output >30 nJ, pulse duration <20 fs, peak power >1.5 MW, beam diameter <2 mm and beam divergence <2 mrad. The instrument, from Femtolasers Produktions GmbH, has an extended cavity and a 900 x 450-mm footprint including the pump laser. It uses dispersive mirrors designed for broadband low-loss intercavity group-delay-dispersion compensation, and the telescope extends the interior length of the cavity. Applications include materials processing, time-resolved spectroscopy, pump-probe measurements and multiphoton microscopy.
