I'm primarily looking for cylindrical lenses to build a telescope to expand the beams from individual laser diodes. For that, I need short concave lens and longer convex lens, for eg. -4mm and +40mm. Additionally, I need (preferably M9) collimators for the diodes, but I found a few options here.

We, the members at the time, all saw it and you bragged about it in the discourse group. Not only are you incorrigible, you are a liar. How about the threats to show up at another forum members home with a shot gun? That didn't happen either?

SUCCESS!!! You are not going to believe what the issue was. Lasermaster1977 your advice was priceless. I took each part of the circuit and checked for appropriate output signals following your advice. I saw that the JFETs were triggering properly, I was seeing trigger signals through...

This seller on ebay might have them, but not listed. He had some fiber to convex 808 nm lenses with AR coating in the past and not expensive, as they go. You could remove the fiber, or leave it on to interface to a FAP. What kind of laser is your 808 nm coming out of? Simple diode, or? What are you...

Or he could have simply said (as I did) that its more complicated than creating an electrical discharge in argon to make an argon ion laser. There is a middle ground between saying "no it wont work" and giving a full lesson on the mechanics of gas lasers, just saying. Its difficult to accept...

Well you can contribute all you want but that doesn't give you the right to talk down to people. I have never called you a name but you have insulted me plenty of times. You're a grown man. Act like an adult. I have nothing against you despite your rancid attitude. Yes 10+ years between your...

Hello M. Polak, Also please allow me bump this thread one again and to offer you great thanks for this post. Unbelievably easy to implement this in software for my ESP32 based test box and ILDA/WAV player ILDAC-WAV (see: https://ildac.com) . I can't quite wrap my head around why the simple math...

After I got the main intended functionality working with the included software, I did not proceed with changing anything further. To be honest, if you want to use it as a stationary laser, I think you will be better served by just buying a cheap show laser instead.

Thanks. I guess they are a pretty old item now.

At this stage in the game, I have only found NOS. Kevin (Junktronix) is who I bought mine from. https://www.photonlexicon.com/forums/showthread.php/23344-Junktronix

Oh yeah, like those sold by Laser FX, Laser Show Systems. I'd forgotten our PLF info exchange in that thread. (I just found Laser FX's weblink on the R4-077). Who else sells them?

In the past, I found that they performed about a 1/4 as well as the g-124s, even as big as they are!! (Of course, that's as-is not comparing to g-124s with the accelerator cards). They are tanks, though!

Awesome and BEEFY! I was unfamiliar with these. Thanks

I actually found a datasheet that I had posted here a few years ago in this thread: https://www.photonlexicon.com/forums/showthread.php/28269-A-102-Open-Loop-Amplifier

This is the guy, R4-077. They look similar to the beefy GS open loop galvos.

I'd like to see what your Stocker Yale actuator looks like. I found one of their linear actuators on line but not much else. We just used thin aluminum strips cut from a soda cans with General Scanning servos for image blanking or beam flags. I posted photos of this on PLF somewhere. On the...

I plan on using a Stocker Yale actuator (a poor man's GM20). I should be able to gradually apply voltage in small increments, inducing very minute deflection. This should give me decent control of the flag. I'm curious now about the shape of the edge of the flag. Perhaps I'm overthinking this...

Please go away.

I'll toss this out there again this year to see if there's any interest. There are (currently) two really nice AirBnBs nearby if people want to save a little cash and not stay in the hotels. All the prices below are including taxes/fees and run from Sunday to Saturday (6 nights). This...
