  1. When Were Lasers Invented? 4/26/2022

    It's been said that Max Planck’s theory in 1900 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.

  2. Montana State University Teaches Laser Eye Safety 4/13/2022

    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.

  3. Pulsed Vs Continuous-Wave Lasers: Understand The Differences 4/13/2022

    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.

  4. How Can You Split A Laser Beam? 3/16/2022

    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.

  5. How Can You Block Laser Light? 3/2/2022

    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.

  6. What Is A YAG laser? 3/2/2022

    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. 

  7. Find Your Laser Power Or Energy Detector With Gentec-EO’s Product Configurator 9/28/2021

    There are many ways to find the laser beam measurement instrument you need on Gentec-EO’s website. Some browse by themselves through our product filter pages, some uses the search bar, while others use our product finder tool.

  8. How Laser Light Is Different From Ordinary Light 9/21/2021

    The sun, stars and fire are natural sources of ordinary light. We recognize the light received by the human eye as white, whether it is the light of a lamp or the sun. However, we do not notice the spectrum of colors that make white, except through a prism by which light can be decomposed into different components.

  9. How Often Should I Recalibrate My Laser Power Or Energy Detector? 7/27/2021

    Now that you got your hands on a brand-new Gentec-EO laser power or laser energy detector, you may be wondering when will you have to let go this awesome piece of technology for recalibration. Or maybe it’s the dusty detector that you found in a colleague's drawer and you are wondering if the calibration is still valid.

  10. How To Know Your Laser Specifications So You Can Choose The Right Measurement Solution 7/26/2021

    If you want to measure the power of your laser, you need a detector and a power meter. There is a wide variety of detectors and power meters available, and not all of them are compatible with each other.
