    Research Group Using Blue Diode Lasers to Fight COVID-19

    Cyparagon you raise some good points, and too be honest I am not super optimistic in the outcome of this project. We are mainly taking this on because there has been a university wide hold on any "non-essential" research, and by doing this we at least get to get into the lab and characterize...

    Research Group Using Blue Diode Lasers to Fight COVID-19

    What you need is a nonlinear crystal, basically think of the atoms of the crystal as masses attached by springs. The laser light can make those springs oscillate at the same frequency as the input light, but in certain crystals if the light has enough intensity you can have the mass-spring...

    Research Group Using Blue Diode Lasers to Fight COVID-19

    Haha, ya we aren't inserting this into bodies. So basically UV-A and UV-B are harmful to us and are the components that cause sunburns, skin cancer, etc. However, once you get down to the UV-C band (which is approx around 220 nm) your dead skin cells or water in your eye absorb the light so...

    Research Group Using Blue Diode Lasers to Fight COVID-19

    I thought I would share these two press releases on the research I am currently working on. We are frequency doubling high-power blue laser diodes to create UV-C light that has been shown to inactivate viruses while being harmless to people. If you see the picture and the video you will clearly...

    Hi From a Laser Grad Student in SoCal

    Hey All, I am a graduate student at UC Irvine in the Physics dept studying ultrashort pulse lasers and laser based x-ray systems. I first found this site while looking for specs on diodes to pump my Ti:Sapphire oscillator that I am building; a big thanks to everyone who has documented the...
