High harmonic generation (HHG) in air medium is experimentally produced by using a state-ofthe-art high power laser system. The harmonic orders up to 35th harmonic are well observed. Optical power
dependence of harmonic spectrum is obtained. Dynamics of a free electron in an intense laser field presents
good agreement with the experimental results. The air medium is used as an interaction medium since air is
a ready source in abundance. The harmonic spectral distribution is similar to that obtained in noble gases.
Experimental results of harmonics produced in air medium follows same trends in terms of plateau region and
cutoff harmonic order, which extends and enhances with increasing laser field.
