    No, that would be very difficult to make from scratch. You'd need a canister of extremely pure helium, a canister of extremely pure neon, glass tubing of various sizes, glass-working tools, a high vacuum pump, etc. I just hooked the laser tube up to a high voltage supply that I made using a single 2N3055 power transistor and a flyback transformer from a television CRT. I used this laser in my Faraday rotation project.
