SANTA CLARA, Calif., July 24, 2006 -- The new ExciStar XS from Coherent Inc. is a compact, economical excimer laser that the company said offers exceptional performance and lifetime characteristics. 

The air-cooled ExciStar XS measures only 649 x 300 x 400 mm, yet delivers up to 10 mJ/pulse at 193 nm with an energy stability of < 2% (1 s), at repetition rates of up to 500 Hz. The use of CoherentExcistarXS.jpgAlmeta XS all-metal-tube construction, corona preionization, an all-solid-state pulser and electrostatic dust removal combine to yield a laser tube lifetime of 500 million pulses and an optics lifetime of 100 million pulses.

The ExciStar XS can operate at 157 nm (F2), 193 nm (ArF), 248 nm (KrF), or 351 nm (XeF). Its compact size and low total cost of ownership will make it particularly attractive to laboratory and research users, especially for marking applications, the company said. The ExciStar XS is RoHS compliant.

GLOSSARY
excimer
A contraction of "excited dimer." The term refers to an excited species made by combination of two identical atoms or molecules, one of which is excited and one of which is at a ground state.
excimer laser
A rare-gas halide or rare-gas metal vapor laser emitting in the ultraviolet (126 to 558 nm) that operates on electronic transitions of molecules, up to that point diatomic, whose ground state is essentially repulsive. Excitation may be by E-beam or electric discharge. Lasing gases include ArCl, ArF, KrCl, KrF, XeCl and XeF.
