Abstract
Laser-beam profile is an important laser parameter that is frequently ignored because conventional measurement techniques are cumbersome. A technique for accurately and rapidly measuring laser-beam profile with a commercial video camera and oscilloscope is described. Both two-dimensional pictures of the beam and quantitative, one-dimensional beam profiles can be obtained. The technique is particularly well suited for biomedical applications because it is compatible with most pulsed and continuous wave visible lasers, it uses readily available and relatively inexpensive components, and it is easy to implement.
