Abstract
We have developed and estimated the measurement system of $CO_2$ and Nd:YAG laser power of wide range. The absorber is made of gold-plated copper cavity. The calibration heater is using a manganin(CuMn12Ni) coil, and output power is measured by using or resistance bridge with composed manganin and copper coil. Developed system can measure 5${\~}$1000W laser output power range. Calibration factors are 489.13J/mV at 100W and 497.04(J/mV) at 500W. correction factors are 0.99 at 100W and 1.006 at 500W.
