Given the pace at which technology advances, there always seems to be a learning curve. With the abundance of consumer electronics available, there typically is no right or wrong way to use these devices — the choice usually comes down to the method that best suits the end user. However, when purchasing a highly advanced…
Are you trying to measure a low-power, slowly pulsing beam (think of a VCSEL beam for example) – and getting frustrated? Measuring low-power, slowly pulsing beams using photodiode sensors can be surprisingly tricky. Learn about the technical challenges you’ll face when trying to measure such beams, and about the Ophir solutions that will help you.…
Ophir BeamPeek, integrated power measurement and beam profiling In laser powder bed fusion (LPBF) processes, metal powder is selectively melted layer by layer using a laser beam. With layer thicknesses of typically 30 to 120 µm, exact adherence to the predefined beam parameters is an essential prerequisite for ensuring that the structures generated exhibit the…
Learn the basic principles, and best practices of laser measurement. You have a laser you’re about to start working with? You have enough experience with other technologies to know that you want to verify its performance; so you start looking for a tool to measure the laser’s…well, what? In other words: Where do I start?…
If you are having problems with the performance of your pulsed laser and suspect that it might occasionally not be firing each and every pulse, then the Centauri power meter can help determine, and log, if and when there are indeed any ‘missed pulses’. Centauri can be configured to detect missed pulses when used together…
Surface micro structuring using ultra short pulse lasers is a unique technology with many applications such as thin film ablation, creating antireflective and optically absorptive surfaces, super hydrophobic or hydrophilic surfaces with anti-bacterial properties, and surface texturing for improved bonding strength. In the semiconductor and display industry, USP lasers perform very well-defined jobs such as…

At its core, calibration is about ensuring that your equipment is working properly and in the way it is intended. Returning your equipment for periodic calibration allows for several things to take place including evaluation of your equipment for damage, opportunities for us to provide education, and upgrades to your firmware, as well as the…
The continuous development of laser technology has revolutionized many areas of our lives in the past decades. The most direct influence on the individual is thanks to advancements in laser technology for medical or cosmetic applications. If you want to ensure optimal results, you have to know – and measure – critical laser parameters. Contact…
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…
When the Sensor Finder gives you a list of solutions for your laser, one of the things it tells you for each suggested sensor is how far below the damage threshold you are.
