Direct Diode Laser


DDL is a laser source that irradiates a focused laser beam from a high power LD module directly onto a target. It is suitable for various purposes such as welding, quenching, brazing, and annealing. The advantages of this laser diode are the small size and low consuption of electricity compared to conventional solid state lasers or CO2 lasers.
