A cascade fiber laser operating at 3.9 micrometers and at 1.2 micrometers in the attenuation minimum of the 3-5 micrometers atmospheric window has been realized with a HO3+- doped fluoride fiber. Two different pump wavelength ranges around 640 nm and 890 nm were used to characterize the laser cascade. A maximum CW laser output of more than 11 mW at 3.9 micrometers and 70 mW at 1.2 micrometers was obtained.
