Laser tests in audience seats.

The spot power indicator has to be set to the specific wavelength being measured, so in this instance it was set for the green wavelength and I was testing only green points with it. I do the other colours too as separate passes. Having been doing it for a while now the power to intensity difference between points of light is obvious for all colours. It's also notable that there is no infrared in the output as often found with cheap disco lasers.

Hello Clive, Great behind the scenes videos. Do you find that some of the blue spectrum dots rate up there with the greens, even though they look dimmer due to the spectral response of the eye? Do you have to take a distribution amongst the colours or do you pretty much get to pick and choose?

I'm actually on the verge of tears. What a letdown.

It was my understanding that there would be sharks...

Michael Thompson

I was going to suggest heavy fog interefers with the projection, but 1) that's probably an extremely ignorant generalization of Scottish weather, and 2) actually sounds like it would look awesome.

Jeremy Impson

I’m a little disappointed that there aren’t any sharks.

Cool story, and it raises an interesting point about "casual" usage of the nuclear trefoil because it "looks badass" (thinking mainly about video games and other such pop culture here). Overuse a symbol enough, and it becomes just another bit of common tat that people are desensitised to. Really not something you want to have happen with a radiation hazard warning symbol, I can understand why your mate was a bit upset. :)

Ah, frickin' lasers. Like so much of our modern technology... troublesome, but also pretty awesome. Not too hot, not too cold, juuuust right. :)

mW, MW ... megawatts, milliwatts, whatever...

I can definitely understand not releasing this one publicly. Neat to see this stuff in action! (An acquaintance is a laser safety guy, and also a nuclear safety guy. He was working the door at a barbots thing where a buddy and I were running Schroedinger's Martini, which uses uranium glassware and a geiger counter to make martinis that are simultaneously wet and dry. I was putting little "RADIOACTIVE" stickers on the plastic cups we gave people. Eventually he saw one, stopped the line at the door, and stormed through to not-quite-yell at us for putting the stickers on all this trash, since he's probably the one who'll get called when someone freaks out seeing it in the trash. Good times, good times.)

good thing that is not 149 kilowatts

What don't they like about the weather? Is water seeping into them, or is it just too hot for them to operate comfortably?

I enjoy this time of year having access to the Tattoo.
