Paper Abstract

The installation and operation of high power lasers, requires to know both the spatial repartition of energy in the beams and their location. Infrared films are less and less frequently used because they require a long and tedious processing. They have been progressively replaced by television systems built around tubes (vidicon with silicon or PbSe targets). Those systems simplify the laser alignment operations, nevertheless their limited dynamic range is an important drawback. In order to replace them by a new generation of cameras, we have studied several CCD sensors and we present the last result obtained when illuminating them with C.W. laser light at X = 1.06 μm and 0.35 We have also tested the behavior of CCD illuminated by a 50 ps laser pulse at X = 1,06 μm. These measurements show that the THOMSON TH 7861 CDA FO sensor has the best features for our applications. The associated television camera is also described.
