Three laser experiments today: laser-induced electroless copper plating, laser-assisted electroplating on stainless steel, and laser-induced chemical liquid phase deposition onto glass. Whoo! I'm using a "20W" 450nm blue laser etching machine for these experiments, and while a bigger or pulsed laser would work better, it did a pretty ok job.
