Abstract
A method and apparatus is provided for generating a laser beam of a wavelength suitable for ablating material. The apparatus includes a source of a laser beam of a wavelength which is not suitable for ablation and a frequency converter which uses harmonic generation to generate a laser beam of a suitable frequency. In preferred arrangements the frequency converter is a non-linear optical material that is maintained at a predetermined elevated temperature. In a preferred arrangement the pulse rate of the laser is selected to maintain the acceptance angle of the harmonic generator within predetermined limits.
