14/2/2019· Re: Laser diode efficiency. For coarse steal cutting they normally use CO2 lasers (10.x µm) - not because of the wavelength, but because they are relatively cheap at high power (several kW). For fine parts (e.g. < 0.1 mm) or marking it is more about blue or maybe pulsed NIR (1064 nm) from laser diodes or solid state lasers - they have less ...
