You can use a neon sign transformer. I did it with a 9kV transformer when I was in high school. Check out this http://www.repairfaq.org/sam/lasercon.htm" .alex caps said:I am a senior in high school and I am interested in learning about lasers. 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 .
A HeNe laser power supply is a device that provides the necessary high voltage and current to power a helium-neon (HeNe) laser. It is an important component in the construction of a HeNe laser, which is a type of gas laser commonly used in scientific and industrial applications.
A HeNe laser power supply works by converting a low voltage, high frequency AC signal into a high voltage, low frequency DC signal. This high voltage DC signal is then used to excite the gas mixture in the laser tube, producing a coherent beam of light.
The main components of a HeNe laser power supply include a high voltage transformer, a rectifier, and a voltage multiplier. Additional components may include a ballast resistor, a current regulator, and various capacitors and resistors for filtering and regulation.
Yes, it is possible to build a HeNe laser power supply yourself with the appropriate knowledge and materials. However, it is important to note that this project involves working with high voltages and should only be attempted by those with experience and proper safety precautions in place.
There are many online resources and forums dedicated to DIY laser projects where you can find helpful guides, tutorials, and advice from experienced hobbyists and scientists. Additionally, there are books and kits available for purchase that provide step-by-step instructions for building your own HeNe laser power supply.
