ABSTRACT:
A detecting or monitoring device for laser radiation is able to oeprate at room temperature and employs a thin film of semi-conductor material of non-centrosymmetric lattice structure having a substantial crystallographic texture; thin film may suitably be tellurium in a film thickness of 1 to 100 .mu.m, supported on a substrate of single crystal silicon.
