Abstract: As the laser industry becomes more mature and sophisticated, more attention is being given to the quality of the beam profile. Burn patterns and visual analysis of reflected beam spots have been the primary technology of the past. Currently, the sophistication and performance of electronic beam analysis has been greatly advanced with a variety of methods available. No one technology provides all of the answers for every circumstance of beam profile analysis. Each provides different advantages, depending on the needs of the user. The latest technological advances are stand-alone instruments that perform very lucid beam profile displays, as well as sophisticated quantitative analysis. These new instruments enable researchers and laser users to obtain much higher laser performance.!0
