Finally...Finally. The big dye laser that I have worked on over the last two plus years, is complete. This is somewhere around the tenth version of this laser. The entire thing weighs in at over 300 Kg and I have designed, built and tweaked EVERY element from the power supply through the optical system; even to the fire suppression system. It has been a long time since I have posted any useful/instructional videos, but both of my "cameramen" will be returning in a couple of weeks and I will post multiple videos, covering operation and the sub-systems and this will (hopefully) be useful to anyone contemplating BIG lamp driven lasers. Not everything I did was successful, there were a lot of dead ends, but that may be as valuable to hear about as what did work and of course...why.
