Abstract :
A calorimeter is described that can measure megajoules of laser energy from CW lasers whose output wavelength is in the region from 1 to 11 ¿m. The calibration of this device is traceable to NBS electrical standards. This calorimeter can measure total energies from 3 × 104 to 107 J. The laser power range this device can handle ranges from 300 to 100 000 W.
