The discussion focuses on building a power supply for a Helium-Neon (HeNe) laser, which is considered a straightforward project for beginners. A participant suggests using a neon sign transformer, specifically a 9kV transformer, as an effective solution for powering the HeNe laser tube purchased from a specific online store. The conversation emphasizes the importance of understanding the construction process beyond merely connecting a tube and power supply, encouraging hands-on learning and experimentation.
PREREQUISITESHigh school students, hobbyists, and anyone interested in DIY laser projects or high-voltage electronics will benefit from this discussion.
You can use a neon sign transformer. I did it with a 9kV transformer when I was in high school.

After a lot of reading I have decided to start with building a HeNe laser as it seems to be the simplest/cheapest to start. I purchased a laser tube ( http://www.lasers.shopeio.com/inventory/details.asp?id=653&cat=Lasers&sub= ) and now I need to build a power supply. I was wondering if anyone could help me with that? Thanks .
