Abstract:
1. A solid-state laser comprising: a solid-state laser medium positioned along an optical path to receive laser pumping light from a laser pumping source, the laser medium having opposing first and second surfaces and being adapted to facilitate generation of laser output having a first wavelength; a Q-switch positioned along the optical path between first and second output ports to transform the laser output into a pulsed laser output for propagation along first and second path portions of the optical path extending from the respective first and second surfaces of the laser medium, the first path portion intersecting the first output port and the second path portion intersecting the second output port, the first and second path portions intersecting each other at neither one of the first and second output ports, and the first and second output ports being positioned along the optical path and on different sides of the laser medium for propagating respective first and second laser machining beams of pulsed laser output; and first and second wavelength converters positioned along the optical path and respectively on different sides of the laser medium, the first and second wavelength converters being adapted for converting the wavelength of the pulsed laser output to a harmonic of the first wavelength such that the first and second laser machining beams have a harmonic wavelength.
