In order to have femtosecond laser pulses tunable throughout the whole visible spectral range with very high stability, we operate a laser system which is consisting of several different parts.

First, we generate the ultra fast laser pulses in a mode locked Ti:Sapphire System. In a second step, the pulses are amplified employing a regenerative amplifier system. The output of this, in turn, is split into several parts, which are used dependent on the actual experiment running.

Either we pump one or two independent optical parametric amplifiers, and/or we use the amplified pulses to generate a femtosecond white light continuum.

A schematic overview of the complete system is shown below.
