Laser 50W 500×300 China. Updated 80-100 Watt tube

 In Projects


Before I start I want to give Russ S. (look for him on youtube) a great big Thanks for all the great information he has shared.

I have almost completed my upgrade to my machine. it started it life as a China 50w machine. (tube was most likely a 40/45 watt tube?) When I took ownership of the machine it was used. So I have no way of knowing the factory state of the tube. What I do know its was damaged and I was able to repair it. (See previous post). I have since retro fitted a Lightobject 45W new tube it was 60mm x 1000mm (bigger the n the tube that came with the unit.) And have again since retrofitted a 80/100 w tube 80mm x 1250mm. I upgraded to all copper mirrors (1″x.25″). as well as an appropriate 100w PSU.

Also, I have (in progress) upgraded to a small DIY chiller. former ice maker.

(Below inspection / access plates) used to gain access to the mirrors.
