When improving laser-based processes, there are a variety of parameters that must be measured. Additionally, the continuously rising power of laser systems in material processing makes the requirements for laser measurement systems more challenging than ever. This white paper discusses laser measurements in materials processing as well as how and when they must be made for the best results.

Silicon photodiodes operate by absorption of photons or charged particles and generate a flow of current in an external circuit, proportional to the incident power. They are used in diverse applications including spectroscopy, beam alignment, optical communications, and medical imaging.

Backside illuminated image sensors have fewer obstacles in incoming light's path as it reaches the pixel volume, where the conversion to charge carriers takes place. Thus, BI CMOS image sensors are able to convert more of the light into charge carriers, resulting in larger signals and better images.

Silicon photodetectors are commonly used for light power measurements but may also be utilized as optical position sensors. They are commonly referred to as Position Sensing Detectors or simply PSDs. This white paper discusses the different types of PSDs and their functions in different applications.

Ophir Photonics offers the 10K-W-BB-45 water cooled thermal power/energy laser measurement sensor designed for very high powers with a 45 mm aperture. The device can measure power from 100W to 11,000W and features a deflecting cone and annular absorber that withstands high power densities to 10kW/cm².
