Airy pulse, especially chirped Airy pulse, has attracted more and more attention and research because of its unique properties. However, due to the complexity of chirped Airy pulses, there are few experimental reports about chirped Airy pulses. In view of this, the chirped Airy pulse can be obtained by modulating the chirped Gaussian pulse in theory, and the modulation mechanism and the transmission properties of the modulated pulse are studied. The results show that the like chirped Airy pulse obtained after modulation is basically the same as the chirped Airy pulse, and has the transmission property of the chirped Airy pulse, which proves the feasibility of the chirped Airy pulse obtained by modulating the chirped Gaussian pulse.
