Abstract
A laser pulse calorimeter which enables measurements of energies within the region of 20-0.02 mJ is described. The calorimeter is a temperature-sensitive resistor, composed of a thin film of black V2O5 evaporated on an 8-μ sapphire substrate of 1-cm diameter. The characteristic peak reading pulse responsivity is 1 mV/mJ, and the accuracy of the measurements at 0.1 mJ is approximately 7%. The calorimeter is sensitive primarily to the beams' energy, and its response is independent of the shape and size of the incident beam of a given energy.
