Will it shorten the lifetime of my laser tube if the power setting is at 100%?
THIS IS A MISCONCEPTION!
Perhaps you will feel that setting the laser tube at its power limit (power set to 100%) might bring negative consequences, especially in regards to the lifetime of laser tube. Indeed, for most industrial products this critical operation might shorten its service life. However, we have to realize one thing first - for a laser tube, outputting at a 100% level is not a kind of critical operation, too high of an unstable current is.
While the power supply of the laser tube is outputting a regular and stable current to the laser tube, no matter which power level you are using, it won’t affect the service time of the tube even if you set the power level at 100% in the driver.
