This invention is for measuring the power of a laser beam by measuring the rate of sublimation of a subliming solid that is being irradiated by the laser. The laser beam radiation is converted to heat within a hohlraum, i.e., a cavity with a relatively small entrance, made from frozen CO2 for example, and the incident power is determined by measuring the rate of change of the weight of the subliming solid.
