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…
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…
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…
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…
The new updated edition of our laser measurement catalog is ready!As in every year – it sets out the comprehensive range of laser power and energy sensors, meters and laser beam profiling systems for medical, industrial, defense, research applications and more. It is an easy and agile round-up with short descriptions and up-to-date technical specifications.…
A new measurement procedure allows for the fast and contact-free measurement of the focused laser beam. At the same time, modern measuring devices have Profinet interfaces and allow the processes to be documented. These are enormous advantages, especially in times of just-in-time production. The challenge – everything has to fit perfectly Automated laser welding is…
Since their invention in 1960, lasers have become a fixture in science fiction, impressing the audience with their futuristic capabilities – namely, extreme precision and power. From Sci-Fi to reality Now, with decades of technological advancement, the gap between sci-fi and reality is closing. These days, lasers up to 70 or 75KW can be produced…
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…
In industrial applications such as additive manufacturing, welding, and cutting, you of course want to keep yields and efficiency high – and keep scrap to a minimum. That means the process needs to be carefully monitored, and the measurements will need to be accurate and fast. Saves you valuable production time (and money) comparing to…
Our revolutionary BeamPeek At laser Munich 2022, we finally revealed our brand new BeamPeek – combined beam analysis & power measurement system specially designed for additive manufacturing chambers. As 3D SLM (Selective Laser Melting) and AM (Additive Manufacturing) systems have gained in popularity for the mass production of metallic parts, the components produced are becoming larger in…
We’re super proud and excited to introduce the Ophir® BeamPeek™, an integrated beam analysis and power measurement system for fast, accurate, real-time measurement of lasers in additive manufacturing chambers. Introduced at Laser World of Photonics (started yesterday), the BeamPeek system provides simultaneous beam profiling, focal spot analysis, and power measurement in just three (3) seconds.…
As every year – Ophir’s new 2022 catalog for laser measurement covers a wide range of laser power and energy sensors, meters and laser beam profiling systems for medical, industrial, defense, and research applications. The first section of the catalog is devoted to laser power meters, which consist of sensors (detectors) and meters (displays). Ophir online tools…
