Claim Text:
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.
