CO2 laser

You will need this couplings,two glass tubes: one 200mm length and 20 mm diameter
(not exactly,its beta-version). Second: 200mm length, 6 mm outer diameter.One high voltage transformer.Vacuum air pump.Water pump and water for running long time.And a very good sealent for connections.Then the most expensive parts: molibden mirror and a salt window for output.
This project is for fun ONLY!!
Be very carefull!!!
I can make some mistakes,cause i m only 13.

Hey guys.This is new update for laser couplings.I added o-rings holders for the better contact and holes for m3 screws on the top of the biggest parts.
