研究目的
Investigating soliton dynamics and dispersive-wave emission in argon- and krypton-filled hollow capillary fibres beyond two-photon resonances.
研究成果
The study demonstrates that soliton dynamics and dispersive-wave emission can be accessed in argon- and krypton-filled HCF, with RDW emission achieved at wavelengths shorter than two-photon resonances. The findings suggest that cladding resonances in HC-PCF may have previously limited observations, and that HCF allows for cleaner investigation of atomic resonances in VUV generation.
研究不足
The study is limited by the ionization effects in Ar and Kr, which become significant at higher energies and affect the soliton dynamics and dispersive-wave emission. The presence of cladding resonances in HC-PCF may also complicate the investigation of atomic resonances in VUV dispersive-wave generation.
1：Experimental Design and Method Selection:
The experiment involved coupling 9 fs pulses at 800 nm into a 3 m long, 250 μm inner diameter, stretched HCF filled with either Ar or Kr to study soliton dynamics and dispersive-wave emission.
2：Sample Selection and Data Sources:
The samples were HCF filled with Ar or Kr at specific pressures to maintain the zero-dispersion wavelength and soliton order.
3：List of Experimental Equipment and Materials:
A 3 m long, 250 μm inner diameter, stretched HCF, 9 fs pulses at 800 nm, Ar and Kr gases.
4：Experimental Procedures and Operational Workflow:
The experiment involved coupling the pulses into the HCF, adjusting gas pressure and pump energy, and observing the output spectra and power as functions of the soliton order.
5：Data Analysis Methods:
The output spectra and power were analyzed to observe self-compression and RDW emission, with attention to ionization effects and wavelength shifts.
