Ti:sapphire & regenerative amplifier laser system
A Ti:sapphire & regenerative amplifier laser system is operated, to produce exciting light pulses up to 800 μJ/pulse at 800 nm at a repetition rate of 946 Hz. The seeding laser is operated at 1/6 of the radio frequency of the master clock (508 MHz) that drives electron bunches in the storage ring to synchronize with the X-ray pulses. Synchronization between the laser and the X-ray pulses is achieved by dynamically controlling the cavity length of the seeding laser. An optical parametric amplifier (TOPAS-C) is also installed, to cover wider spectral regions from visible to mid-infrared.
