ABSTRACT:
This invention relates to the modification of lasing medium surfaces, such as crystals, to reduce the internal reflections that contribute to amplified spontaneous emission (ASE) losses. A laser ablation treatment involves focusing an optical irradiation means on a target surface having desired ablation pattern and ablating the target surface according to the selected ablation pattern. A cross-hatch pattern on the target surface is secured by the target surface being mounted onto a precision motor driven translation stage and stepped throughout the desired ablation pattern. The optical irradiation means are oriented initially at 45.degree. to the target surface length and subsequently rotated by 90.degree..
