摘要: An excimer laser includes a laser housing containing a lasing-gas mixture including a halogen. Contaminants including particulate matter and a metal halide vapor are generated in the lasing-gas mixture during operation of the laser. A gas-cleaning arrangement extracts lasing-gas mixture from the housing and passes the lasing-gas mixture through an electrode assembly. A repeatedly pulsed gas discharge is created in the electrode assembly by driving the electrode assembly with repeated high-power short-duration pulses. The pulsed discharge causes disintegration of the metal halide vapor and electrostatic trapping in the electrode assembly of the particulate matter and products of the metal halide disintegration.

摘要: A process for the determination and correction of laser induced damages of the optical and electronic components within the beam path of a monitor module of a 193 nm excimer lasers is provided herein. Especially state of the art detectors like CCD cameras degrade under UV radiation. With a special correction of the sensitivity of each camera pixel this problem can be solved.
