    All valid points, Brian. The rotating linear diff wasn't an issue within the planetarium dome, but was a very diff matter when queuing a net of beams over the heads of audiences with a 5 watt laser system. Inspectors tend to frown upon audiences being hit as they rotate into position. That's when I...

    Interesting collection of sfx hardware, Greg. I see a few concentric shafts (for multiple sfx glass), arms for sf mounting and levers, springs for returns... But, there are no solenoid actuators to make it run, like pistons rotating a crankshaft, with rods & linkages. Are you needing to mount a...

    Hi everyone! I’ve been reading into semiconductor lasers and came across DFB and DBR lasers and while I understand, superficially, the difference between them, I fail to find an application or necessity that would absolutely need a DBR laser and couldn’t be done with a DFB laser or VCSEL...

    Laser Images’ scan through actuator technique worked. The Hermit commented that its rotation into the beam path was a questionable feature, but that didn’t bother me. The scan glass comes up on a musical cue – the rotation is to the cue – the cue is over and so is the rotation – but the scan glass...

    Send me a picture of your galvos and I'll see what I have laying around. I have some old Xlaser amps from a project that went nowhere

    Hi everyone, I've got a set of ScannerMax 506s I ordered from Pangolin back in 2015 before Pangolin's amplifier was available. Since then I had a no-so-good experience purchasing amplifiers from a member here, in the end he sent me four small amps after the original pair of amps he sent didn't...

Le barreau est pompé en continu et le facteur de qualité du résonateur est maintenu au plus bas pour que l'inversion de population soit la plus élevée que possible. ...

    Here, due to the triple whammy of a show tape, video footage, and the secrets recounted by a performer, is rock around the clock fairly close, probably, to what was originally intended. How clever to use spiral sweep and rotations in this way. I agree that losing this content to the dust of time...

    I just want to say that Ivan took pride when a reviewer wrote that Laserium was a visual art of the future. To help that happen required that the covers come off so anyone who wants to make that future happen could see what the past was about. Thank you Greg for illustrating the past and the...

    Who knew a couple of months after my last post our Planetarium would be shutdown till now! The Institute was very cautious with capacity, now back to 90% pre Covid. One of our 2016 Able 2.5 watt lasers has a red module that stopped outputting light. Probably has only 400 to 500 hrs on it. With...

    I see how what I said may have sounded critical. Honestly, I was just poking fun at myself. That is, I have always wanted to "hijack" something but a "thread" is as extreme as a polite Canadian is likely to get. *I* would like the freedom to prattle, though I assume readers are more interested in...

    Greg, the idea of a new thread is a nice one and I think would draw lots of interest. Your interest and desire to unravel, preserve, recreate and synthesize the famous Laser Images show tapes is inspiring. The trails that you and those like the creators of Radiator have blazed what can be...

    With grateful humility, may I say I agree. It is amazing progress to have soldered this ridiculous tangle of wires together and out plops Laserium into my lap. Back in the early 1990s I saw in a university's machine room full of fridge sized reel to reel mag storage, all that stuff, and there was...
