A Simple Power Meter for Measuring Outputs from a High Power Continuous Wave (CW) CO2 Laser
Abstract
The design of a power meter for measuring continuous wave (CW) outputs is presented. The principle of the operation is to measure the temperature rise at the surface of an aluminum slab that absorbs the energy of the incident 10.6 micron radiation. In order to make effective absorption, the surface is covered with a layer of Al203 of a few microns in thickness. Linear response to the incident power up to 200 W and allowable power density of more than 500 W/cm2 are attained.
