title: Simple and sensitive CO2 laser visual screen.
abstract: The present paper describes a simple and sensitive CO2 laser visual screen which is made from silica gel with cobalt chloride as indicator. The screen can directly and almost immediately display a clear mode pattern of an exposing CO2 laser beam, it can respond to laser intensities ranging from 80 mW/cm2 to 26 W/cm2. It is suitable for the observation of both high-power lasers, which are used for surgery, and very low power ones, which are used for biostimulation.
