Efficient Raman generation in a hydrogen-filled hollow-core fibre

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) configura...

Description
Summary: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.
