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

I just got an email back from CNI — they said they're no longer shipping portable lasers to any customers. End of an era indeed. :-(

I realize this is an old thread but have been wondering about this too. It does look like CNI has stopped making handheld lasers (even Class IIIa laser pointers) altogether because they no longer appear in the catalog as of early 2020. Even resellers like Optotronics and Dragon Lasers have been...

I realize this is a very old post but wanted to share my latest findings. The good news is that Soraa has been developing laser diodes during all this time. The reason their official website didn't say anything about lasers is that the R&D was being done by a spin-off company called SLD Laser...

I was just thinking about this thread the other day and was wondering how accurate it has been.

If a DPSS laser is dropped and hits a hard surface, then its optics may become misaligned.

I did read the Wikipedia article, but it hasn't changed much in over 10 years. The last time someone added new information was in 2010, and that got removed as copyright violation. However, this sounds very promising: Does this mean we can expect future laser diodes to have really high...

I did find some websites claiming to have them for sale: https://www.laserdiodesource.com/shop/1310nm-6mW-TO-can-quantum-dot-QD-Laser http://ldselection.com/product/1548 https://imm-photonics.de/en/products/optoelectronics-and-components/laser-diodes-and-laser-diode-modules-from-qd-laser#c787

I recently became aware there is a new class of solid-state lasers based on quantum dots. From what I gather, they're supposed to have really good specs. However, there doesn't seem to be much information about them. So my questions are: 1. How energy-efficient are quantum dot lasers compared...

A long time ago, everyone said that all 405 nm lasers are single-mode. It seems this no longer the case. Considering that single-mode operation is required for optical disc drives, these diodes are likely intended for projectors and such.

Are these lasers still single-mode? I didn't see anything this in the spec sheets, but other diodes with similar specs are apparently all multi-mode.

Posted this in Discord but thought I'd share it here too. One idea to reduce spam would be to add an additional CAPTCHA on the sign-up page. For example, there could be a question like, "What does LASER stand for?" A side benefit is that this would require the user to do at least some basic...

Another common one that hasn't been mentioned: LF = looking for.
