You can use a CO2 laser system to perform on almost every material, including metal and non metal parts. The only limitation might be the reflectiveness of the piece. (Those gold little pieces you mention mustn't be too much reflective so that the light could affect the material surface). The typical spot diameter is of about 0.2-0.3 mm but you can de-focalize it to get a bigger size, being able to get a feature of 2 or 3 mm.
