Abstract
A broadband source device configured for generating broadband radiation or white light output. The broadband source device includes a gas cell, and a hollow-core photonic crystal fiber at least partially enclosed within the gas cell. A gas mixture is within the gas cell and the hollow-core photonic crystal fiber. The gas mixture includes at least one Raman active molecular gas constituting more than 2% of the gas mixture, such that the broadband source device operates in a balanced Kerr-Raman nonlinear interaction regime.
Claims19
A broadband radiation source device, configured for generating a broadband output, the device comprising:
- an optical component, comprising:
- a gas cell, and
- a hollow-core photonic crystal fiber at least partially enclosed within the gas cell;
- and
- a gas mixture within the gas cell and the hollow-core photonic crystal fiber, the gas mixture comprising at least one Raman active molecular gas constituting more than 2% of the gas mixture,
- wherein the broadband radiation source device is configured to operate in a balanced Kerr-Raman nonlinear interaction regime and output an output spectrum of the output radiation that is flat and/or smooth over a range of wavelengths.
A method for generating broadband radiation using a broadband radiation source device comprising:
- an optical component comprising a gas cell, a hollow-core photonic crystal fiber at least partially enclosed within the gas cell;
- and a gas mixture comprising at least one Raman active molecular gas within the gas cell and the hollow-core photonic crystal fiber and using a pump laser in optical connection with the gas-filled hollow-core photonic crystal fiber, the method comprising:
- measuring output radiation, output from the optical component;
- and
- evaluating the measured output radiation so as to determine whether the broadband radiation source device is operating in a balanced Kerr-Raman nonlinear interaction regime, wherein the evaluating comprises evaluating whether an output spectrum of the output radiation is flat and/or smooth over a range of wavelengths.
