Laser Output Detection

  • Leon Goldman

Abstract

It is, of course, necessary to know the output of the laser. In the biomedical field it is much more important to be precise and accurate. The laser reaction in living tissue changes with but small changes in the various parameters of the laser output, whether it be changes in power, energy outputs or pulse duration. The findings of laser research at various centers cannot be compared unless accurate outputs of laser radiation are made. This important field is in a very much confused state at the present time because of the difficulty of measurement of laser output, especially of high outputs. Exit energies above 1500 joules exit energy have been used in biomedical applications with the pulsed solid-state lasers, 0.5–10 watts power outputs are to be used for the argon laser and 25 watts for the carbon dioxide laser. It would seem, at first glance, that the problem of measurements should be simple, for it is merely the detection of classical changes in electromagnetic fields. Many studies of this problem have been done in our laboratory by Hornby and Rockwell.
