Abstract
A stable optical laser resonator is formed by two mirrors facing each other. At least one of the mirrors operates as a decoupling device for decoupling a coherent, pulsating laser beam from the resonator. For this purpose the decoupling mirror has a zone or zones which are permeable or partially permeable to the laser beam. These zones are located in predetermined areas of the mirror and the size of these zones is relatively small compared to the total effective mirror surface. Preferably, the active lasing medium is limited to a narrow cross-sectional area perpendicularly to the optical axis of the resonator. The narrow cross-sectional area has an approximately rectangular shape for enforcing the one-dimensional oscillation movement of a laser beam.
