Paper Abstract

A thermal tube based high power and energy meter is introduced, which uses a thermal tube as an isothermal receiver to realize an upper range of 1 X 106 J by the effective thermal conduction the tube and the elimination of thermal lag, with a total uncertainty (mu) less than 5%. A non- contacting method for measuring the laser off-beam power and energy is also described which can indirectly measure the beam power, energy, peak power, waveform and laser pulse frequency by measuring the off-beam scatter based on the principle of the functional dependence of beam on its scatter. Finally a description of a ceramic attenuation meter for high-peak power and energy is given.
