METHOD AND DEVICE FOR PUMPING A LASER

摘要

The invention relates to a method and devices for pumping a laser, and to a laser element, which is specially designed therefor and which contains laser-active material. In order to prevent the laser-active material from being subjected to excessive thermal stress, particularly during a thin disk setup, an, in essence, elongated pumped light spot is irradiated onto a laser medium placed on a temperature sink whereby producing a two-dimensional heat flow. This achieves an improved cooling and a reduction of the maximum temperature.
