Quick question: With a fair amount of yellow lasers your CMOS cameras often fail to see the yellow and show it as green. I always thought it was because the red channel on a bayer filter is simply not passing anything to the red part of the sensor and thus it's green. Lately I've been told im...

So. I have been working on getting my finances in place to be able to join the world of Show lasers. I would love to travel. And work with an Artist Creatively. Eventually but Just being able to purchase large show lasers is Really Really hard. I live in Grand Rapids. MI. Located 3 hours from both...

I found this green wavelength DPSS cavity interesting, anyone ever see one of these specific laser cavities before? Curious what it might be out of. https://www.youtube.com/watch?v=GvKyKeSZIaU

In this multi post series, I'll describe step by step series how I built by ECDL setup. Let's start with physical construction. Design In this build, I'll use diffraction grating to reduce the bandwidth. The grating will be operating in Littrov configuration. In this case, it's ...

Hello Folks! I have a question on scanners. Since my regularly work is with laser graphics / animation related shows. I need your suggestions on having good scanners in my 30 watt RGB laser projectors. Is EMS 8000 or EMS 9000 good for animations or is there a better ones. Thanks Rupesh

Hi everyone. This post might sound a bit foolish, but I've recently acquired a laser (ilda clubmax) at what I believe is a great price. It made me decide to jump head-first into this. With that aside, I am trying to understand what DAC I should get. For context, the laser also has a saturn1....

I have a need for one or more power supplies for the Lightwave Electronics model 221 10W ND:YAG laser. Does anyone know if the PS/controller for the 211 is compatible, except for the needed diode voltage and current? The controller interface pin-out on the 221 otherwise looks identical to the 211,...

Does anyone have any information on connector descriptions for the older EyeMagic ema-2000 amps? These were used along with the EMS 7000 scanners. I attached a picture of the amp, need to figure out what connections are what, one circled in red and the other connector I circled purple…. TIA!

Greetings, all; A little late with this, but still very important: The students of Saint Wilfred’s Lumentic Institute Department of Hyperbole are excited to release their second publishing effort: Culinary Lasers Monthly magazine. Under the direction of Professor Poul DeOtherwon, the...

I got mooned in my own backyard- nighttime right in the middle of the day. Anybody else see it?

Hey guys, I have a couple of 591nm laser modules that I would like to put into my lumia projector. I like to fade in/out my lumia effects and also control the brightness. These summation lasers don't work well, or at all, at low power levels so fading/attenuating via modulation is out. Since...

Looking for the software of verity sd100 monochromator unit. It was manufactured back in the late 1999,2000 era. Tried to contact the manufacturer but they don’t have the software for this legacy device. So I am looking for any information on this device to try and operate it vis the rs232.port....

Cr:YAG as Q-Switch @1064 nm, how much trouble is it to just add one in the cavity as a passive Q-Switch? Can it be that simple for an existing ND:YAG at 1064 nm? I'm expecting to hear back it isn't so simple and the cavity would need to be redesigned, or?

Just finished playing guitar at our worship services. It was great. HAPPY EASTER! and blessings to you all.

I recently purchased a used Avantes AvaSpec-2048 spectrometer, it's consistently reading a bit more than 1.2 nm high, the HG-1 calibrator allows me to see that and mentally subtract the error from the measurement, but I'd like to have the instrument reading correctly. If anyone has...

For any console guys out there, I wanted to share what I've found with the sine/cosine potentiometer from P3 America. Back story, many years ago I came across the Hallpot Resolver and added it to my console. I tied this to z rotation so that I could flip between a running oscillator or the...

Here is your chance to get 2 laser show DACs for a really cheap price, to use the default software you need a Windows XP or Windows 7 PC with an LPT bi-directional port. USB to LPT probably will have problems In 2007 Norm said these were compatible with the following softwares - NLS...

Hello, I'm looking to purchase an FB3 if anyone is selling. I have used Beyond, Quickshow, Liberation and Lasershowgen. My personal Mac is not powerful enough to run Liberation even though I think it is great. Quickshow seems like the one I want to run on my personal lasers but for the time being...

Edit: Edmunds prices are not that bad, after all. Disregard post.

Anyone know a source for a high voltage capacitor suitable for a "SSY-1" ND:YAG laser for sale anywhere? I want to charge the cap to 500 VDC but it needs to be able to handle rapid 5 to 10 Hz charge and discharge firing. No, not one YAG, I have a dozen of them I want to fire one at a time...

Hi All. I am trying to rebuild some old 100mW green lasers. I am hoping that someone here has seen this type of PCB before. I controls the X and Y scanner motors. I am trying to find out what kind of signal there is on the black yellow and white wires. Those are the control signal in. The...

tl;dr: making a first-time scanner purchase for hobbyist & professional use in UK clubs and festivals. Which suppliers should I be looking at, and what non-obvious things do I need to know? Hi all. I'm a UK-based club lampy, been a laser fan since around 2010 when I was an active member of LPF...
