Abstract
Thulium and holmium have become the rare earth dopants of choice for generating 2 micron laser light in silica fiber. The majority of Tm: fiber lasers are pumped with high power diodes at 790nm and rely upon cross-relaxation processes to achieve optical-to-optical efficiencies of 55-65%. Tm: fiber lasers can also be pumped at <1900nm by another Tm: fiber laser to minimize quantum defect, reaching efficiencies >90%. Ho: fiber lasers are similarly pumped by Tm: fiber lasers at 1900-1950nm, with <70% typical efficiency. In this work, Tm: fiber and Ho: fiber lasers are in-band pumped using the same experimental setup to directly compare their performance as 2 micron sources.
