Optically pumped solid body laser for material processing comprises an intracavity laser crystal having an optical axis along which a continuous pump light source or pulsed emitted pump light source is directed into the crystal

摘要

Optically pumped solid body laser comprises at least one intracavity laser crystal (6) having at least one optical axis along which a continuous pump light source or pulsed emitted pump light source (7, 8) is directed into the crystal. The pump light source has a beam diameter corresponding to 1.25 times the beam cross-section of a laser beam formed within the resonator (R) with the oscillating mode TEM00.
