Ah, good catch. "Single-mode" certainly has a different meaning when you're interested in the technical details of a laser. :) If it were up to me, I'd have used something like "Single function" instead.

I once read that the average power of the original Sonar is closer to 2 mW. Violet lasers have definitely gone a long way.

Yeah... repeatedly trying to pick a fight with people will get you banned in a lot of places.

There's definitely something fishy about Sanwu. The customization option lets buyers select between single-mode and multi-mode, even for lasers rated at several watts. Here's an example: https://sanwulasers.com/product/challengerii However, my understanding is single-mode diodes are generally...

I can think of a few reasons for the decline. 1. People are migrating from traditional forums to websites like Reddit nowadays. 2. The novelty factor has worn off as lasers are now a lot more common than they used to be. Using a laser to pop a balloon or light a match no longer has a "wow"...

I didn't see it with my naked eye but did manage to capture a faint glow on my phone. You can see the unmistakable colors in the photos.

It's my understanding that this forum's rules do not allow users to have multiple accounts. So this person was already breaking the rules whether or not he was evading his ban.

There's a company called Berlin Lasers that is selling a single-mode 445 nm laser diode that they say can go up to 1.6 watts: https://berlinlasers.com/445nm-single-mode-blue-laser-diode I'm guessing it's just a mistake and that they simply put it on the wrong page, but I'm curious to see what...

Anyone else disappointed that the U.S. didn't shoot down the balloon with a laser?

I know this is quite an old thread, but it looks like the question has been answered. Zraffleticket and rajhlinux have found that the diodes used in the BDR-209 drives are of Sony make. Here's the datasheet for those curious: https://datasheetspdf.com/pdf-file/905921/SonyCorporation/SLD3237VF/1...

Glad I'm not the only one! I did once write to Wicked Lasers to suggest that they sell the Spyder I Pro host to hobbyists who want to assemble their own lasers. Although they liked the idea, I guess the demand wasn't high enough. Nice collection, by the way. :D

One thing I noticed is that the most popular lasers today have fancy-looking designs that resemble lightsabers and Gatling guns. However, I've always preferred the simplicity of CNI-style lasers. Although I already have the now-discontinued Spyder I Pro from Wicked Lasers — which actually looks...

I can't wait for AI to help us design more efficient lasers. :D
