Abstract
Generation of ultrashort mid-infrared pulses in Raman gas fiber lasers is investigated. Using a hollow-core revolver fiber filled with a mixture of molecular deuterium and hydrogen gases, Raman generation of ultrashort pulses at λ = 3.9 μm is realized for the first time. The pulse duration of 4.6 ps is obtained, and the pulse energy as high as 10 μJ is achieved at λ = 3.9 μm.
