Processing device, especially for laser engraving, marking or inscribing has pump light from diode laser fed to laser rod essentially along straight line that intersects rod cross-sectional area

摘要

The device has a solid state laser rod (13) with transverse pump geometry optically stimulated by at least one diode laser (11). The pump light emitted by the diode laser is fed to the laser rod essentially along a straight line (G) that intersects a cross-sectional area of the laser rod and lies at a distance from a longitudinal center axis (L) of the laser rod.
