Efficient frequency doubling of 1.5µm femtosecond laser pulses in quasi-phase-matched optical fibres
Second-order nonlinear gratings in optical fibres have been produced for efficient quasi-phase-matched frequency conversion around 1.5µm. Periodic poling was achieved by defining a patterned electrode on a D-shape fibre via standard lithography and applying high voltage (4-5 kV) at elevated temperat...
