18 – RF And Glass Tube Laser Cutting Comparison

The Tangerine Tiger Series with Russ Sadler

In this Series, Russ has purchased a new 500 x 300mm, 50W laser machine from eBay with a view to modifying and upgrading it. In fact, he rips out the glass laser tube and high voltage power supply and replaces them with an RF laser source and PSU from Cloudray. Find out how the expensive RF laser source compares to a glass CO2 laser tube and prepare to get your hands dirty! So lets investigate this RF And Glass Tube Laser Cutting Comparison.

If you are considering purchasing a CO2 laser machine with an RF laser source from one of the big boy suppliers, I would suggest you check out this series before making a decision!


Thinking that my RF laser was just 20 watts (with a bit of extra power for warranty purposes) I was surprised by the initial cutting tests on 3mm Baltic birch plywood. Perhaps there was something “magical” about the cutting power of an RF tube after all!!!!. Were the “big companies” marketing claims correct after all? The truth was required. In this session I set about comparing an RF tube and a glass tube running at exactly the same watts and with the exact same test conditions. Let’s see if I am confirming facts or shooting down myths.
