We demonstrated Attosecond Lighthouse technique in gases and extend the driving laser pulses to longer wavelength.This technique allows the direct observation of dynamical effects in the non-linear medium itself on attosecond pulse generation process.With longer driving laser wavelength we generate spatially well-separated beamlets from low ionization potential gas media.We also find that there is little long trajectory contribution--only the short trajectory contribution is clearly visible for any beamlet.
