A UV Faraday rotator for the high power KrF laser system and other UV excimer lasers has been developed for the first time. Pure water has high Verdet constant and high transmittance in UV region (up to 190 nm). Ninety degree polarization rotation of a KrF laser beam is obtained by passing through a 5 cm long quartz cell filled by pure water. Quartz rod has also been proved to be equally useful as a Faraday rotator for KrF lasers.
