Coherent Inc.’s HighLight DL HPS is an industrial diode laser that offers 1 kW to 4 kW power output in a compact, self-contained package. It is useful for systems integrators and end users performing metal cladding, heat treating, brazing and welding. The laser head, power supply, water chiller and heat exchanger are all contained in a single enclosure. The enclosure measures 670 mm by 1,050 mm by 1,760 mm. The conduction-cooled laser diodes enable the closed-loop chiller to utilize distilled water for easier implementation.
