- Info on building lasers (CO2, HeNe, N2, dye, others) is available in a
- Scientific American reprint book "Light and Its Uses: Making and using
- lasers, holograms, interferometers, and instruments of dispersion" by
- Jearl Walker, published by W.H.Freeman & Co.
-
- Some of the lasers described:
-
- HeNe: Your basic low-power red laser.
- Argon: Multiple colors.
- Dye: Tune thru a range of colors.
- CO2: Infrared output of around 8 watts (a serious power that "quickly chars
- wood")
- Diode: How to use diode lasers (this field has improved since this article)
- N2: ~75 kilowatt ultraviolet output in 10-nanosecond pulses.
-
- Side note: air-based lasers can be built. There's enough nitrogen in air to
- produce a lasing action. I'm still kicking myself for not
- taking up Peter Dowben (Syracuse University physics professor)'s offer to
- help me build one out of, as he put it, $0.25 in materials.
