The area of the window subject to infrared laser beam (particularly, CO2 laser beam) becomes translucent, and the beam propagates through it. The clearly visible translucent spot allows to perform conveniently all the alignment tasks as well as to judge about the power and energy distribution of the beam. Broadband IR viewers are available for laser beam power operation range extending from 100 mW to 3 W. The response time is around 50 ms being a function of the laser beam power. These IR viewing films are inexpensive and can be manufactured in different sizes.
