    Improper mounting of lasers

    RedCowboy, I don't feel like making a new thread about this, so I will just tag it on here. I got around to "modifying" my first laser purchased - a Dragon Lasers 35 mW Viper (Green). I assume it is a 532 nm laser source, but after checking the receipts, it doesn't explicitly say the...

    Improper mounting of lasers

    I felt it might be valuable to share this as a new member to this hobby. I have taken laser safety very seriously, and own a pair of "Eagle Pair® 190-540nm & 800-1700nm OD5 Laser Safety Goggles" (the $65 option). I am building my first laser using one of those $15 NICHIA M140 (A140?) diodes...

    Wow...."super chiral" laser...

    Research like this is incredibly important. Although they must spin it (ha, get it?) with a heavy application-focused approach, the researchers are really doing fundamental science which has implications in many fields. To the best of my knowledge, there isn't consensus on why biological...

    Laser for Street Lights

    I agree with Paul. I had a similar situation at my old apartment, and I just had to send a few emails and wait a week. Success will vary depending on your local government's or power company's responsiveness :)

    F#CK Windows 10

    The best part is, Windows 10 is supposedly the last major revision of the OS. It's already so clunky compared to more barebones OS, I can't imagine what it will look like in 5 years.

    Build a $10 burning laser

    New member here. Would you recommend similar "advanced current regulators" as drivers of higher power laser diodes? Many of the posts I see use more complicated circuits to do what this single component appears to be doing, and I'm curious if it is scalable.

    Precautions to take before observing a laser in the sky

    Hello LPF! I just started this account after purchasing a 35 mW Viper from Dragon Lasers. I have been using some cheap red glasses that designate they are safe for 532 nm. However, my question is not about eye safety. It's about the safety of planes. I live in Tuscaloosa, AL (United States) I...
