Resumo
This work reports the generation of Below
Threshold Harmonics generated in Argon by ultrashort laser
pulses. The 3rd, 5th, 7th and 9th harmonics of the laser were
generated in the UV and VUV regions, and the frequency
conversion occurred in flowing gas in a glass nozzle into a
vacuum chamber. The harmonics generated show a blue-shift
and an efficiency that depend on the laser pulses intensity and
also on the gas pressure. These parameters determine the
phase-matching condition, which governs the energy
conversion from the laser into the harmonics, and this study
shows that is possible to tune the harmonics intensity and
wavelength, providing a versatile light source.
