50 Watt Laser Tube

I’m a little confused about the length of a 50 watt laser tube. Is it correct that it can be 710 mm long, that’s what the seller says …? I have no information on the tube diameter.
I would expect it to be a 40 watt tube.


The so called 50W machines really only have a 40-45W tube in them. Some basic sizes are as follows:

35W - 710mm long X 55mm diameter
40W - 800mm long X 55mm diameter
50W - 1000mm long X 55mm diameter
60W - 1200mm long X 55mm diameter

Thanks for the answer. It is sad that a 30/35 watt laser is being anonized and sold as a 50 watt laser.
