Abstract
Drilling of small holes into media containing OH or CH bonds with a 2.92 µm YAlO3 : Er laser is studied. In materials containing OH bonds strong absorption allows to heat small volumina with only marginal heat diffusion. Drilling with nearly diffraction limited lateral resolution is achieved.
