The EX50/1000 35W KrF Laser

For applications requiring high repetition rate and moderate average power, when you need a compact air or water cooled laser, the EX50 is the choice. The EX50 excimer laser offers state of the art performance in a compact package. The EX50 provides a highly reliable powerful source of ultraviolet radiation. Four models with repetition rates up to 250Hz, 500Hz  and 750Hz  are available with average powers to 35W with KrF at 248nm and 18W with ArF at 193nm. Long gas lifetime gives up to 1 year of operation between refills with XeCl. For applications in precision micromachining, tunable laser pumping, marking and semiconductor processing.

The EX50 laser is a total metal/ceramic device of advanced design. The carefully selected materials used in the laser construction give the EX50 static and dynamic gas lifetimes unmatched by any other excimer laser.
