Hi Viktor, Thanks a lot for your answer. I really appreciate. You said "Shorter wavelengths are better". So why we do not use 100nm ou less other than 445nm ? How do you choose the best wavelenght ? (ex : If I want to cut green paper ? engrave wood ? Glass ? ....)by ArmyBoy - Laser Cutter Working Group
Hello, I'm new in laser technologie... I saw in different topics that for cutting purpose, people will use 445nm 1W 1 - does it exist a laser with an ajustable power (watt) and/or an ajustable wavelenght ? 2 - a laser with for exemple with a wavelenght 780mn or more, does it could cut the same materials than the 450 nm ? does it would better to have a superior wavelenght than 450nm to beby ArmyBoy - Laser Cutter Working Group
