  1. The Relationship Between Laser Fluence And Pulse Duration 9/13/2022

    Laser fluence is a useful metric to know how concentrated the energy is spatially. It tells us nothing, however, about how fast that energy is delivered. This is where pulse duration comes into play.

  2. 3 Things To Know About The Average Power Of Pulsed Lasers 7/6/2022

    If you owned a fleet of delivery trucks, how much would it actually help you to know just the average delivery time per parcel? On a fast day, what could you really conclude? Are drivers getting lucky, using less traffic-prone routes, driving outside of rush hour, stopping for coffee less often, or even pushing the trucks way past the speed limits?

  3. How Many Photons Are Produced In A Laser Pulse? 6/2/2022

    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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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.
