Dilas Industrial Laser Systems has unveiled power extensions for its compact diode laser system series: 300 W out of a 200-µm fiber and 400 W out of a 300-µm fiber at 9xx nm. The fiber-coupled turnkey diode laser systems are based on conduction-cooled diode laser bars. The systems are available with an industrial water-to-air chiller, a power supply and an integrated control unit. The 19-in. rack mount makes the laser and the cooling unit easy to integrate for OEM purposes. The systems can be combined with a variety of accessories for process control, including laser processing heads, cameras, pyrometers, galvo scanners and galvo scanners with integrated pyrometers. In combination with a galvo scanner, they can be used for quasi-simultaneous plastics welding.
