Solid state laser with multiple cores coupled by fold optics

摘要

A laser rod assembly includes a first and second laser rod embedded in a cladding material. The assembly has a first end and a second end. The laser rods generate laser light at λlaser (λlaser light) when pumped by pump power at λpump. A reflecting outer surface at λpump is on or over a majority of an outer surface of the cladding material. Fold optic(s) on the second end provides optical coupling between the laser rods. An optical resonator includes a highly reflecting (HR) mirror at λlaser over an end of the first laser rod on the first end and an output coupler over an end of the second laser rod also on the first end.

1. A laser rod assembly, comprising:
a first laser rod and a second laser rod embedded in a cladding material, said assembly having a first end and a second end, said first laser rod and said second laser rod each including a host material both doped with a lasing specie(s) for generating laser light at λlaser (λlaser light) when pumped by optical pump power at λpump; a reflecting outer surface at said λpump on or over a majority of an outer surface of said cladding material above and below said first and second laser rods; fold optic(s) on said second end for providing optical coupling between said first laser rod and said second laser rod, and an optical resonator for providing feedback of said λlaser light for supporting lasing comprising a highly reflecting (HR) mirror at said λlaser over an end of said first laser rod on said first end and an output coupler over an end of said second laser rod on said first end for emitting said λlaser light as an output beam.
