In this paper we propose a method for an isolated attosecond pulse generation using the combination of fundamental chirped laser field (5 fs, 800 nm) with two chirp function and a controlling laser field (10 fs, 400 nm). It is shown that by inserting optimized chirped parameter in fundamental laser field, plateau of the high order harmonics would be broadened. Furthermore, because of importing chirped pulse, quantum short trajectory is enhanced and long trajectory is suppressed. By superposition of properly selected range of the harmonics spectrum in the continuum region, an isolated attosecond pulse is generated.
Keywords: Isolated attosecond pulse, High order harmonics generation, Chirped two-color laser field
