Old Helium Neon lasers
A working HeNe tube is shown below running at 2 kV with a 330 kohm resistor. It takes about 3 – 4 kV to trigger. It is shown firing through a 15,000 lines per inch diffraction grating and shows the first order spectra.

Argon Laser 40 mW Blue
Argon Laser 40 mW Blue Laser, multi-line. Unusual in that it has multiple spectral lines. Of course these days, simple handheld diode lasers can be much brighter than this. The power supply and control unit are on the left and the head unit with fan on top. The beam is highlighted by a water spray. I love electronics with a key start.
