Abstract
EMI radiation from the laser head of a copper-vapour laser (pulsed discharge laser) are mapped in the near field with a characterized pick- up probe. This is followed by simulation of the laser head as a microstrip antenna and also as a loop antenna. The modification of radiation characteristics of these antennas by the inclusion of a metallic sheet with many shorts is studied with the aim to minimize radiated EMI. Shielding of the laser head feed cable is also simulated.
