Efficient energy transfer between two ultrafast laser beams is reported. Energy transfer occurs when linearly polarized donor and acceptor beams are focused in air and intersect at an acute angle. This effect is attributed to plasma-mediated forward stimulated Raman scattering, facilitated by supercontinuum generation. Donor depletion as high as 57% is observed, with quantitative energy transfer from the donor to the acceptor beam. Amplification of the acceptor depends on the polarization directions of the two pulses and the delay between them. Interaction between the beams results also in compression and spectral broadening of the acceptor pulse.
