  • Many elements such as the optical components and surrounding environment have an impact on the energy your laser beam delivers. The intrinsic noise of the pulsed laser is also an important factor since it has a large impact on pulse-to-pulse energy stability. In this webinar, you will learn how to measure laser energy accurately.

  • On day one of SPIE’s Defense + Commercial Sensing 2022 trade show, Fel Legrand from Gentec-EO introduces the company’s latest releases for laser power and energy measurement applications.

  • Félicien Legrand with Gentec-EO met with us on the second day of Photonics West 2022 to explain why your time is better spent developing improved laser processes when compared to the time invested in setting up laser beam diagnostic tools. He also gave us a brief introduction to the new Miro Altitude – a laser power display and energy device ideal for even the most demanding applications.

  • The second generation of the INTEGRA is a meterless line of all-in-one detectors that combine a detector and a meter in one device that lugs directly into your PC. Each detector of the INTEGRA series offers the same incredible performance as the usual detector and meter combination, from pW to kW and from fJ to J. For a brief introduction on this product, watch the video.

  • The BEAMAGE-4M is a beam profiling camera designed for accurate profile measurements of very small beams. The camera utilizes a USB 3.0 for the transfer rates up to 10X faster than regular USB 2.0 connections. Check out the video for a brief introduction.

  • The PRONTO-SI is a portable photodiode-based laser power meter designed for up to 800 mW that is so compact it fits in your pocket. Check out the video for a demonstration on this device.

  • The MAESTRO is a touchscreen display device for power and energy measurements within thermopiles, photo detectors, and pyroelectrics. The device features a large touch screen LCD display with 18bit color and 640 x 480 resolution.

  • The PRONTO-250 portable laser power meter is a mid to high power probe measuring laser power up to 250 W and is small enough to fit in your pocket. This easy-to-use power meter features a color LCD screen, a friendly user interface, and fully calibrated settings for every wavelength between 248 nm and 2.5 μm (YAG), and a real calibration at 10.6 μm (CO2).

  • 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. 

  • Gentec EO developed the first CO2 laser energy meter in the world in 1972. They may be nearing their 50th birthday, but COlasers are nowhere near retirement. This article takes a look at what CO2 lasers are, what they can do, and what applications they're best used in.

  • Gentec EO explores the many uses of laser wavelengths in this application note. Topics explored include common laser wavelengths in telecommunications, which wavelengths are needed and used for laser eye surgery, and how wavelengths are applied in laser welding applications. 

  • Electronics, specifically lasers are more commonly used today than you may realize. Gentec EO explores a few common examples of laser applications in electronics in today's world.


  • Ever wondered how many photons make up one laser pulse? Of course, it depends on the laser, but Gentec-EO can give you some ballpark numbers, and will also show you how you can compute these values for your own laser setup.

  • It's been said that in1900, Max Planck’s theory that energy is emitted and absorbed in discrete chunks called quanta, was the first building block for laser development. Einstein built on this, predicting in 1917 that photon emission could be stimulated by the passage of other photons.

  • The Optical Technology Center (OpTeC) of Montana State University won a Pyroelectric detector for laser energy measurement  in the first edition of the Gentec-EO Laser Lab Awards. Their use of the detector? Laser eye safety and education.

  • Continuous Wave (CW) lasers can deliver immensely different powers, requiring a broad range of measurement solutions that Gentec-EO has developed over the last 50 years.

  • Beam splitters are optical components that partially reflect a laser beam, so the initial laser beam is split in two: a reflected beam and a transmitted beam. Gentec-EO designs beam samplers for high-power laser beams, based on the plate beam splitter principle.

  • Do you need to momentarily shield a target from a low-powered laser? Are you looking for a safe way to halt a high-power beam’s propagation? Or is it eye protection you seek? Different needs, different solutions.

  • YAG crystals are man-made garnets that can be used as gemstones for jewelry, but their main use today is in the laser industry. Interestingly enough, perfect YAG crystals are useless for lasing. It is literally their imperfections that make them usable.
