1 year 364 days ago, I went on an insane trek across Ohio to get a ruby laser. It was a fixer-upper...
This is a whitelight copy of a transmission hologram made with that laser. Poorly composed and my expression is a bit bug-eyed (it was completely dark, I had positioned my nose with a ruler (1 foot from the plate), and was about to press a very ominous Button), but the entire process came out.

To put things in perspective... Its at most a 1 joule laser. A joule is a watt for a second, a nightlight is 15 watts, it puts out 15 times the energy of this laser in a second. The exposure time is about 20 nanoseconds, so the beam is carrying 5 megawatts (for 20 nanosecnds), but the delivered energy is only 1J.
A 22 caliber bullet, you know the little dinky ones, delivers 435 J.
The most significant hazard is the power supply, which consists of capacitors weighing about 400 pounds, which contain about 3000 J (so don't open the cover). The second most significant is eye damage. I did a not insignificant amount of research and pondering before sticking my head in front of this thing... (-:
