    Convert a red HeNe to yellow

    I've always wanted to play around with HeNe optics to see if I could get something other than red from one. I recently noticed that Sam G. sells HeNe optics of various colors on eBay so I figured I'd give it a shot. I ordered up a set of yellow HeNe optics and spent hours trying to get yellow...

    Analog Abstracts

    If I'm not mistaken, there's a number of folks here that use sound card dacs? If so, I uploaded a flac file (compressed wave) that you're welcome to have. It's about 7 minutes of changing color modulation on an abstract. Swamidog was kind enough to record it...

    Hi all, I have a couple lasers that I'm willing to let go: **Available**1st up, Laser Physics Reliant - This is a multiline aircooled argon laser that runs on 110VAC. I did meter this laser last year at SELEM and it was putting out around 105mW and 7 lines at full current. This is the model...

    Lexel Ion Laser Optics

    By any chance, does anyone have a set of lexel optics floating around? Maybe from a dead Lexel 95 or 85? Looking for a multiline set.

    Laser Physics Reliant teardown

    Tore apart a 1W Laser Physics Reliant for repair, thought I'd grab a couple pics while it's in pieces. I'd say just a little bit of current has flowed thru that one connector on the board![/sarcasm]

    This is an old school way of doing color modulation. Just to the left is a set of scanners, one to move the beam to the side so that it gets blocked after the prisms and before the X/Y scanners (blanking), the other scanner is to sweep the beam up and down on the prism (color modulation). Just...

    CNI yellow laser pointers for sale

    Hi all, ok, I picked up a dead CNI 589nm pointer here on LPF a few weeks ago. I took it apart and played around with it for a while and threw it back together. Was never able to get yellow out of it. Not sure of it's warranty status or even if it would be repaired by CNI since it was taken...

    Trying to resurrect a CNI 589nm pointer.

    Hi all, ok, I purchased this pointer here about a week or two ago. I knew full well that it was dead but was looking for a challenge. I've got the thing disassembled down to the driver and pump diode. I'm suspecting that there is an issue with either the pump diode or the driver. Being a 589nm...

    CNI GLP-589 noob review

    Some time ago I saw a guy at SELEM with a 593.5nm pointer and just couldn't believe it. I've owned a yellow HeNe and a Krypton that put out yellow in the past and to see this in a pointer, that was just cool. I waited a while to see if the prices would come down and I'm glad I did, not only did...
