Holmium fiber lasers pumped in-band with Tm fiber lasers appear as interesting solutions when looking for high power in a single spatial mode and high electro-optic efficiency, in a spectral domain that guarantees eye-safe emission and low absorption by the atmosphere. We will present the progress of our work on a high efficiency holmium (Ho) fiber laser, detailing the numeric model, experimental realization and results.
