چکیده    High harmonic generation is a useful tool for the generation of short, intense attosecond pulses. in order to simulate high harmonic generation, we performed a numerical solution to the time dependent schr ouml;dinger equation. by considering dipole approximation, we predicted generation of a 53 attosecond pulse. in order to see the time and frequency of emission of attosecond pulse, we exploit time frequency analysis. on the other hand, because of uncertainty between time and frequency, it would be of high importance whether which analysis is been applied. our studies show that gabor analysis exhibits the least uncertainty between time and frequency components. and at least, we set the balance between time and frequency distribution by altering the window size.
