Abstract:A thin-film line array of thermoelectric detectors is applied for the measurement of intensity distribution of focused laser beams. The damage threshold of these detectors is relatively high. They can tolerate 50 μsec pulses with intensities as high as 3·105 W/cm2. High resolutions can be achieved by fabricating line arrays having a large number of thermoelectric junctions with distances as small as 5 μm between centers.
