    Laserium shows began at Griffith Park's planetarium in 1972. I 'experienced' my 1st in 1977, before becoming a London Planetarium laserist the following year. The RYGB laser was a Spectra Physics krypton 164, with broadband optics and optimized gas pressure to produce the 4 distinct colors. Laser...

    You could also consider NDR Lighting as a viable alternative for LED lights.

    Having retired from paid work a little over a year ago I've been occupying my time with various projects and assorted loose ends. One of the things I've been doing is resurrecting my various laser projects. I've been experimenting, designing, prototyping and doing a lot of documenting on it...

    Interesting. I also had a planetarium laser show, "Laser Floss", that incorporated Billy Thorpe's 6min. 44sec. "Children of the Sun" during 1980. It was attractive for planetarium and laser effects rendering.

    The point spitter, normally called the DOG card, had a 6500 family processor, eight eight bit DACs, and was quite a capable digital image synthesizer that output some of the earliest graphic frames in laser show history. As well, the device could generate a small catalog of cycloids and motion...

    Never was a convergence of fine physics so pretty as the Spectra Physics 168 Argon Ion Laser. It was the mixed gas Ar/Kr option that gave multiline output of red, green, yellow, and blue in shows of that era.

    Fascinating! So, were these mostly RGB displays? Or single color? Were the colors merged to create 7 colors similar to TTL lasers of today? The point splitter doesn't sound like it was galvanometer driven, so perhaps it used stepper motors? I suspect the PPS was quite slow back then. I wonder if...

    Wow. I don't know what DOG PROMs are, but the fact that someone other than myself has knowledge of this show at all is amazing. So, I take it you had a hand in its presentation? Do you recall anything about it? It was before I had seen my first laser show, so I don't know what the technology in...

    The short of it is that about a hundred people were in the audience, and by the third number they were cheering and applauding. Part of that was the choice of music. Great feedback after the show. A lot of people wanted to know more about what they had just seen and heard. Also I had a camera on a...

    My all time favorite album, hands down, is an obscure record from 1980. It was the follow-up to the one-hit AOR album Children of the Sun by Billy Thorpe. The album, 21st Century Man, released in 1980, was intended to be "bigger and better" than the record that contained the 1979 hit that most...

    OD3 or OD4 are typically used for "Aiming" glasses. Off the shelf sun glasses are maybe OD1.5, and their coatings and materials are not rated nor designed for lasers. They often have coverage gaps etc. Welding goggles are not for laser safety either. At 1.5 meters off a non specular or ...
