    Have CNI-style lasers gone out of style?

    I think CNI stopped shipping portables to the U.S. in 2014: https://laserpointerforums.com/threads/cni-no-longer-exporting-5mw.88382 Which is unfortunate because CNI makes the largest variety of handheld lasers. It might still be possible to get them shipped to the U.S. via a foreign freight...

    Have CNI-style lasers gone out of style?

    Yeah, I noticed Dragon Lasers is one of the few remaining companies that still sell CNI-style lasers to consumers. I remember people used to criticize Dragon Lasers for selling under-powered lasers, but it's been a while since I've heard any complaints about them. It's probably safe to assume...

    Have CNI-style lasers gone out of style?

    I just realized I haven't been on this forum in over a year. Things have changed so much while I was gone! Speaking of which, one thing I noticed is that people seem to be straying away from CNI-type lasers. I remember NOVAlasers, Optotronics and Laserglow being the most highly recommended...

    New purple laser isn't a dot

    I thought most 405 nm lasers were single-mode?

    Official specs of BDR-209 diode?

    I wouldn't be surprised if the manufacturer is making these diodes exclusively for Pioneer under an agreement not to disclose the information. Some OEMs do make units exclusive to one customer. For example, CNI produces the Hercules series for Laserglow and no other company. How likely is it...

    questions about "301" and "303" lasers

    Thanks for all the information. I must admit that the Sanwu hosts look especially nice. I really hope they'll make more powerful lasers in that form factor.

    questions about "301" and "303" lasers

    I know that these lasers are pretty popular among some members. They're made by a number of different companies but typically have "301" or "303" in their name. From what I could tell, these lasers are considered crap, but many people still buy them because of their low price. The hosts also...

    Official specs of BDR-209 diode?

    It's my understanding that the BDR-209 diodes are presently the most powerful single-mode 405 nm laser diodes available. But from what I could tell, the BDR-209 is technically the Blu-ray Disc drive marketed by Pioneer Corporation. I could barely find any official specs about the diode itself...
