Nuvonyx ISL laser material processing systems can be operated in continuous wave or pulsed mode, delivering up to 4,000 W with complete control of the laser power. The system is capable of operating perpendicular to the surface of either aluminum (70% reflective) or copper (95% reflective) at more than 4,000 W for 24 hours of continuous operation. The ISL-2000L, ISL-4000L and ISL-4000L HD laser systems provide light energy with linear polarization at a center wavelength of 805+/-10 nm. The minimum pulse width is 1ms (100 microsecond, optional) with a duty cycle from 0 to 100%. The laser has a working distance from 40 to 90 mm (1.5 to 3.5 in.) with a spot size from 12 mm x 0.5 mm to 6 mm x 0.4 mm (0.5 x 0.02 to 0.25 x 0.15 in.).
