Efficient Raman generation in a hydrogen-filled hollow-core fibre. (September 2015) - Gladyshev, A.V.
Abstract: Efficient Raman generation in a molecular hydrogen-filled hollow-core fibre having a cladding in the form of a single ring of capillaries has been demonstrated for the first time. The pump source used was a -switched Nd : YAG laser with a pulse duration of, and a single-pass (cavity-free) configuration was employed. The maximum average output power at was, and the differential quantum efficiency was 87 %, a record level for such experiments.
