A dual-wavelength cladding-pumped Er-doped ZBLAN fiber laser emitting around 2.8 μm
Le résumé fourni par la source
We demonstrated a dual-wavelength cladding-pumped Er-doped ZBLAN fiber laser emitting around 2.8 μm for the first time. The laser was jointly cladding-pumped by a 1.568 μm fiber laser and a 1.68 μm laser diode. The system lifted pump constraints innovatively with LD cladding-pumping and achieved enhanced efficiency with dual-wavelength pumping, while its thermal-management advantage was validated by simulation. At the maximum output power of 1.3 W, the overall optical efficiency was 19.1% relative to all absorbed pump and the fitted slope efficiency was 45.9% relative to absorbed 1.68 μm pump power. Optimal pump wavelength, dual-wavelength pump power relationship, and basic pump choice were investigated, providing critical insights for high-power, high-efficiency and low-thermal-load 2.8 μm fiber laser systems.
