Abstract

The mechanism of voltage generation in thin metal film detectors is investigated. For this purpose non‐oxidized Bi films of different widths and thicknesses are prepared and irradiated by a cw Nd‐Yag laser. Voltages are detected in all the samples. In order to detect nanosecond pulses, a pulsed Nd‐Yag laser is used to irradiate oxidized as well as non‐oxidized samples. Pulse lengths of 14 ns are observed by thin Bi film detectors. A theoretical calculation of voltage as a function of thickness is made by calculating the temperature rise in the Bi films and compared with the measured voltages.
