Drying with diode lasers is a cost-efficient and environmentally friendly alternative to the widely used convective oven drying. With homogeneous area spots, even large surfaces with side lengths of up to 2 m can be irradiated. In principle, all materials that exhibit sufficient absorption for the laser wavelength can be dried. The laser beam heats only the coating, thus yielding a targeted evaporation of the solvent or even sintering on the workpiece.

Especially in times when highly efficient electrified solutions are sought in the face of gas shortages and rising energy costs, this could become the standard.
