    Research Group Using Blue Diode Lasers to Fight COVID-19

    You're both getting right at the heart of this problem and why this hasn't been offered yet as a commercial product. Although, luckily it is a bit more of an engineering problem than a physics problem--this process works, but you need a high intensity single-mode beam. With the advances in diode...

    Blue Laser Based on Frequency-Quadrupled Tm:Lu2O3

    This is very interesting to see. Thulium has some very interesting properties as a gain element where you can get a "two for one" upconversion process that can make it very efficient. A group at LLNL is pushing for Tm:YLF as a gain material for a kW average power petawatt class laser. During my...

    Hi From a Laser Grad Student in SoCal

    Thank you very much for your reply. Honestly it has been kinda difficult for me to figure out exactly what models are out there and currently in production. So far I have mainly used DTR's Laser Shop and it seems like he does a good job of updating what is available, but it's good to know that...

    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...
