  • Pulsed laser power measurement depends on repetition rate, pulse duration, and power meter technology, which vary depending on power range and application.

  • The National Ignition Facility at Lawrence Livermore National Laboratory is partnering with Gentec-EO for the integration of custom laser energy detectors for laser beam diagnostics, energy measurements, and calorimeters control solutions.

  • UVs span from 150 to 400 nanometers. This is a short wavelength for a laser, and that has a lot of advantages. UV lasers can also cut and mark with almost no thermal distortion. What’s more, they are compatible with a plethora of materials. All this combines to make them the go-to laser for sensitive high-precision applications.

  • Not all laser applications are as futuristic as Star Wars, but some of the applications involving high-power lasers get pretty close! From nuclear fusion to measuring the distance to the Moon, lasers have found all sorts of surprising uses.

  • Gentec-EO’s new IS power detectors combine the speed of photodetectors with the attenuation of integrating spheres. Combining these two technologies with Gentec-EO’s own recipe for a high damage-threshold absorber offers many advantages.

  • One of the most common uses for fiber optics is high-speed internet. However, fiber lasers can do so much more. In addition to transporting preexisting laser light, fiber lasers also generate it. Gentec-EO explains how fiber lasers work, the advantages of using them, and how to measure them with their product line.

  • Laser precision allows for better quality welds, faster throughput, reduced post-processing costs, and access to new domains of application. However, the hefty price tag can pose a challenge. Gentec-EO discusses the advantages of laser welding and how its measurement solutions can justify the cost of equipment.
