Intro To Laser Management: Laser Profiling 101
By Mark S. Szorik, Ophir Photonics

Traditionally, laser operators only verify a laser’s average power or energy to improve efficiency and, if everything is in order, put their laser back into service. This article discusses steps required to identify and use a camera profiling system (arrayed camera, attenuator, and beam dump) for laser management.

Eye Surgery Using Excimer And Femtosecond Lasers
