    quantum dot lasers?

    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...

    "Assassin" handheld lasers?

    Has anyone here used one of those lasers? We have a few of these lasers at work in our hardware labs. I couldn't find much information about these lasers, but they seem to be identical to the SDLaser 301 or 303 models. Although we don't have any balloons, matches or anything to test their...

    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...

    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...

    anyone have experience with Insanity Lasers?

    There's a company called Insanity Lasers that seems to have recently popped up. I frequently see their ads on Facebook but couldn't find any further information. Their pictures indicate that the lasers use the same host as the "SDLaser 303" ones. But other than that, I'm a little suspicious for...
