Special cooling and stacking techniques makes the production of high-power diode lasers possible, achieving the same power levels as conventional gas or solid-state lasers. By stacking several semiconductor laser bars to diode stacks, output powers of 1.5 kW per stack can be produced. The output power can even be increased to more than 3 kW by the combination of several stacks by means of wavelength resp. polarization coupling.
Diode lasers are extremely compact laser beam sources which are the perfect tool for applications like heat conduction welding, brazing and hardening.
