Laser beam profiling and infrared cameras

Laser beam profiling and infrared cameras


Raf Vandersmissen



The spatial intensity distribution of a laser beam is one of the key parameters to understand how a laser will perform in an application [COH]. For some applications, it may be sufficient to measure the beam profile during the design or fabrication phase of the laser, for other applications, real‐time continuous monitoring during laser operation is required. For example, in some scientific applications lasers are pushed to the operational limits and continuous measurement of the beam profile is necessary to ensure that the laser is still operating as expected. Also in industrial laser cutting or welding applications, monitoring the beam quality is critical for successful operation [WAL].

In this white paper, we will address the general need for laser beam profile analysis. Further, we will briefly describe laser beam analysis instruments and give an overview of laser applications, in particular for infrared wavelengths.
