Take this laser

In honor of this, some facts about ruby lasers:

A ruby laser is a solid-state laser that uses a synthetic ruby crystal as its gain medium. It was the first type of laser invented, and was first operated by Theodore H. “Ted” Maiman[1] at Hughes Research Laboratories on 1960-05-16[2].

The ruby laser produces pulses of visible light at a wavelength of 694.3 nm, which appears as deep red to human eyes. Typical ruby laser pulse lengths are on the order of a millisecond. These short pulses of red light are visible to the human eye, if the viewer carefully watches the target area where the pulse will fire.

Sounds like Blume couldn’t repurpose the ruby on her ring for a laser, then, and good thing: it’s busy!

On the other hand I can only imagine that the now deceased Mr. Maiman would be tickled that his invention — created at the behest of the defense industry — would now inspire such warm feelings in at least a couple of his fellow humans.

If I were creating the world I wouldn’t mess about with butterflies and daffodils. I would have started with lasers, eight o’clock, Day One!

Evil, Time Bandits (1981)

Bit of a stick in Evil’s eye, too, I must say. We use our rubies for lasers… of love!
