Laser enhancement of radiation detection sensitivity of a YBCO film

Abstract

We repoii exprimental results which demonstrate the laser enhancement of the sensitivity of a YBalCusO+a film as a radiation detector and the existence of a non-thermal optical response. The bias continuous wave laser beam enhances the sensitivity at higher chopping frequency range (more than 80 Hz) new the critical temperature of the film. The enhancement shows the non-bolometer response.
