Abstract
Subnanosecond detectors and beam monitors for pulsed CO2 laser radiation using the photon drag and optical rectification effects in tellurium are presented. Tellurium devices at 10.6 μ have a response of the order of 80 μV/kW . cm-2with an NEP of 
W . Hz1/2and 
of 500 cm . Hz1/2/W which is superior to commercially available photon drag detectors and monitors. It is also expected and experimentally demonstrated that the responsivities of large area monitors can be multiplied by cutting the original area into multi-element strips and electrically connecting them in series.
