A model experiment for stand-off sensing Conference Paper uri icon


  • Two aspects of the stand-off sensing technique (Kocharovsky et al. Proc. Natl Acad. Sci. 2005, 102, 7806-7811) were demonstrated using a femtosecond laser system and an organic dye. First, three cells of a solution of Rhodamine B dye in ethanol were pumped with a single wavelength. Amplification of the light generated by two-photon absorption occurred when the pulses were overlapped temporally, in a direction opposite to that of the pump laser beam. Second, the dispersion of the dye solution permitted two pulses of different wavelength to overlap at a specified location in the solution. The overlapped pulses generated light as the result of two-photon absorption in both the forward and backward directions, relative to that of the pump laser beam.
