Expo 86 in Vancouver, they had an exhibit on lasers and compared to todays standards a very basic laser graphics demonstration and a nightly outdoor beam show and cloud scanned logo during the fireworks. The outdoor laser was an argon about the size of a truck, not sure of the power level but likely not much compared to todays standards.
That piqued my interest and soon I did a report in Grade 6 I think on lasers, along with an animation I made in autodesk animator on the school's apple IIA year later I convinced my parents to buy me a 5mW hene and I was hooked. It came with a book which had some projects such 3 mirror motor, mirror / speaker and home made galvo scanner builds. I worked through those and then got into holography for a year or so, I think around grade 8 or 9.
Couldn't really go much further at the time due to the costs of laser hardware in those days but stayed an interested in the back of mind for many years. Eventually stumbled on an 18mW green pointer (at the time quite expensive and rare), of course quickly got bored of pointing and so took it apart to turn it into a lab laser and dug out the old 3 mirror motor builds and such, and a few other projects.
Then a couple of years later saw an 350mW (50mW 532nm, 300mW 658nm) rgy chinese laser for sale and bought it. Disappointed with the stepper motor scanners and general performance I took it apart and modified a bit, but never really was happy it. I knew about ilda and pangolin, but just couldn't afford it at the time.
Then the fb3 came out and as soon as I discovered that I built a 1W rgb. Not too long after completion a friend convinced me to bring it out to his night club shows. As no variance is needed in Canada, I eventually agreed to give it a try, though anxious as was extremely paranoid of the potential dangers and had built that laser with the intention of a hobby rather than a business, but thanks to photonlexicon I had fully researched safety techniques such as aperture masking and was able to take it on with some level of comfort.
It spread word of mouth from there and pretty much immediately was in the laser show business. As business picked up, I just kept building as funds allowed. And has steadily increased over the last number of years.
