Laser tube ratings are interpreted differently by different companies. For example, some companies sell 750mm tubes as 40W or even 45W. That’s accomplished by turning up the current past rated limits - either once on the test bench to justify the number, or in the product permanently, with predictable effects on tube life.
We also have a lot of other magic going on that improves cutting efficiency beyond watts, much of which we don’t talk about. Doubly so over time - for example, dirty output couplers are a permanent drag on output power and eventually tube life; our design solves that permanently. (You can see that just by looking at it, which is why I mention it as an example.
Many of our improvements are not detectable without specialized equipment and a knowledge of what you’re looking for.)
