    I'm not quite sure why the claims that I bought my son a Mercedes using Pangolin money is being brought up again on Facebook, but apparently that narrative is being resurrected. I really don't participate on Facebook very much any more, because of all of the vitriol that is found there -- plus...

    Hi, does anyone have some experience with the polygon scanner assemblies from laserprinters ? Most of them are very slim, and I would like to land a multimode beam on them. So I'm looking for polygon mirror assemblies that have a aperture at least 4mm high. There are lots on ebay and Chinese...

    I'm working on a simple beam expander for some Taipan lasers. One negative lens and one positive lens with a mechanism to adjust the distance between them. Commercial units all seem to use achromatic lenses. Is there any advantage to using an achromat over a simple (i.e. cheap) spherical lens when...

    Hello there. I've recently been looking into the Wicked Lasers Lasercube, and it seems like a great buy especially considering its price and capabilities. However, that little thing is a Class IV laser and outputs wayyy too much power for my prospective applications. I was hoping to use it at...

    Can someone tell me what this is called and possibly who makes it? I know it changes the beam direction 90 degrees, that about it. It has a crystal in it and it is powered I think to move the crystal.

    I "very" loosely understood how fiber lasers actually worked but I found this video on youtube that really helped me understand fiber lasers a lot better. Very cool, worth a watch if you're curious. I still can't believe how much lasers have changed in the last 30 years since I first started...

    I just got confirmation that I've located a pic of the first commercial green laser pointer. It was produced in Moscow in 1993 by Laser-Compact Group, and distributed by Laser2000 in Europe and Power Technology here. The ad below shows it, from Photonics Spectra magazine of September, 1994. The ad...

    Well, for green laser pointers it's really old. Here's the model GP4 made by the Taiwan company Limate in 1998. Along with the operational laser, I got the wooden box, the outer box, instruction sheet, brochure, and the receipt for its purchase in January 1999. The laser gives a double beam output...
