Femtosecond laser induced conical emission in alkali vapor
We report the observation of cone emission generated when ~10 nJ, 100 fs laser pulses in 700-850 nm wavelength range are transmitted through dense alkali vapor. The spatial and spectral characteristics of the observed cone emission were studied experimentally. Cone angle dependence on the laser wavelength, laser average power and atomic and molecular concentrations were investigated. The cone emission (CE) was only observed when the laser beam self-focused after passing through the medium. Several characteristics of the CE obtained in this experiment, such as the laser wavelength range in which it appears, large CE spectral blue detuning and high laser-CE energy conversion, are quite unique for femtosecond laser induced CE.
