In welding and cutting, since lasers are very volatile, often your laser can feel like a stranger to you. You might know that you are using a CO2 laser of a certain power level but you can tell something is off kilter – you just can’t figure out what. Continued

Lasers and IPLs (intense pulsed light) are used for a wide variety of aesthetic treatments. Here is an overview (summarized from this article by Burt Mooney) of some of the therapies and the types of lasers used for each. The types of lasers used changes over time as new technologies evolve. Continued

Q. There is a certain group that works with fibers. dB (decibel) measurements are the typical measurement unit used in their business. Is there an option in the power measurement values to select dB rather than watts? Continued

The accuracy of power and energy meter calibration is dependent on many factors. Among others, these factors include:
1. Wavelength: Measuring heads need to be calibrated at a few wavelengths since absorption differs with change in wavelength. Continued
