Oh yeah, that's the actual beam alright. Look how opaque it is. At 150mw and below almost every beam that you see is opaque. It takes a beam several watts before you can even begin to see the beam becoming anything close to transparent.



ElectroFreak: If it is, that's impressive.. I'm calling BS on that being the actual beam though. It just doesn't look quite right.

^That's a nice system.. I'm sure it costs plenty. I'd love to have on though, but there really isn't a laser that i wouldn't like to have.

aaaah, still noone here with a spare ruby-rod? come on! this could be a lot of fun! :)
(not that there would be lots of applications for us to turn a watt of coherent 405nm light into some dozen mw barely visible 694nm pulses.. hehe)

but wow, does ruby fluorescence under 405nm light! it looks pink, not 694nm, but it surely is bright!

Long ago, during the first debut of the laser, a CW arc lamp ruby laser was produced in the bell labs. I believe it used a Hg arc lamp to produce something on the order of 10's of mW... talk about a waste of energy!
