Abstract
In the last JAPS-OSA Joint symposia, we reported the enhancement of the generation efficiency of ultrabroadband coherent infrared pulses from air plasma driven by hollow fiber compressed two-color 10 fs pulses, by controlling the polarization of two-color pulses using a dual waveplate [1]. However, the mechanism of the enhancement has not been fully understood; the simple analysis taking only the group delay dispersion of the βBBO crystal and the dual wave plate indicates two-color pulses do not overlap at all at the focal point where plasma is formed. In the present paper, we report the result of a systematic study on the dependence of the generation efficiency on the thickness of optical components and nonlinear crystals employed for the air plasma based infrared pulse generation.
