Abstract

The changes of transmissitivy and refletivity of ion-implanted Si with time under intense CW CO2 laser irradiation have been measured. It is discovered that there is enhanced absorption of intense CO2 laser by silicon. This phenomenon may be explained qualitatively by means of free carrier absorption.
