UV femtosecond complete laser systems

UV femtosecond laser systems are based on the combination of short pulse seed lasers emitting visible or infrared pulses, and special KrF excimer modules for the amplification of the frequency upconverted seed pulses.

UV fs vario

A UV femtosecond laser system usually comprises a Ti:sapphire front end laser as a seed pulse source. This is typically a commercially available device of renowned laser manufacturers, adapted to the requirements of the UV laser system. This means that its emission wavelength is set to 745.5 nm. The system is shipped with a compact and robust frequency tripling unit. Regardless of the choice of the amplifier module, the system is delivered with a synchronization unit to insure long term synchronism between the seed laser and the excimer amplifier. The system specifications correspond to those of the selected amplifier modules (see UV femtosecond amplifiers).

LLG ultimate

In this configuration the seed pulses for UV amplification are provided by a special dye laser system. The dye laser is pumped by a separate XeCl excimer laser which is synchronized to the KrF amplifier. The emission wavelength of the dye laser is set to 497 nm. After frequency doubling in a thin BBO crystal the pulses are amplified in a KrF excimer device. The system specifications correspond to those of the selected amplifier module (see UV femtosecond amplifiers).
