CHIRP CONTROL METHOD AND CHIRP CONTROL APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a chirp control method and a chirp control apparatus capable of controlling chirp in a terahertz pulse wave.;SOLUTION: In the chirp control method for controlling chirp in a terahertz pulse wave generated by interfering pulse width-expanded pulse light obtained by expanding pulse width of inputted pulse light, generating intensity-modulated pulse light having periodical intensity modulation and applying the intensity-modulated pulse light to a terahertz wave generation part, the pulse width-expanded pulse light is generated by an expansion part in which variation Φ(ω) of a phase is expressed by the formula (1) to control the chirp in the terahertz pulse wave expressed by the formula (2).;COPYRIGHT: (C)2014,JPO&INPIT
