Laser Rebuild – Part 5 (Bench Testing)

Not much to say about this.  It’s scary cool!   The tube glows pinkish purple and the wood block ignites instantly.  The only thing I’ve seen ignite faster was the imagination of my 12 and 10 year old sons.  Something about that glow inspires a guy to try stupid stuff.  Fortunately eye-protection was the order of the day and no injuries were reported.
