High-Power Laser Measurement: Cooling Methods
Measurement of high-power lasers requires efficient heat control in power measurement sensors. Choosing the right heat transfer method is a critical step in configuring a reliable, accurate high-power laser meter. The following article, written by Asher Izsak, sr. mechanical engineer on our R&D team, explains why choosing the right heat control method is one of…

High Power Lasers – Just Measure It
Laser power and the applied laser densities are constantly rising. These high-power lasers are more likely to be used in materials processing applications such as welding, cutting, cladding, or additive manufacturing. Many of those applications are demanding: The laser’s focal spot and beam profile need to be kept within the specification to achieve the required…

Watch: Managing Laser Degradation in Industrial Applications
Lasers are made of physical matter. Therefore, the natural degradation of their materials can cause variability in performance. Aging optics often cause slow changes in laser behavior and, when left unchecked, these changes can lead to loss of process efficiency. An unclean process environment can quickly change a laser’s behavior through thermal lensing, which is…

Destroy the Target, Not Everything Else: Beam Management in High-Power Directed Energy Laser Projects
Since Columbia University graduate student Gordon Gould and Bell Laboratories scientists Charles Townes and Arthur Schawlow (among others) coined the term LASER in the 1950’s, applications of the laser have seemed limitless. Working with these new discoveries had to be exciting, but applying hundreds of kilowatts of laser power, like the ones being used in…

On-demand Webinar: High Power laser measurement challenges and solutions
Monitoring laser behavior in high-power applications is critical to keeping your process running properly. However, that monitoring – the laser measurement itself – is not trivial. There are many “little things” one could do that might unknowingly mess with the measurement, or even damage the instrument. For example: • At what point should the cooling…
