A high-power diode laser operating at 810 nm is used as a heat source in a nickel carbonyl CVD process to coat polyurethane foam with nickel. Advantages and disadvantages of using laser source compared to conventional infrared lamps are discussed. Deposition rates up to 3 µm/min on a 3-D surface of open-cell polyurethane foam have been achieved. The reactor window design is simplified compared to the conventional system.
