Abstract
In this paper we will present a new autocorrelation method for the IR FEL optical pulsewidth measurements at Vanderbilt University. This met hod is based on absorption of radiation due to two-photon absorption ( TPA) of Ge, InAs, and Te semiconductors. The theory of this method, al ong with the experimental setup and autocorrelation measurements utili zed are presented. Also results of this method are compared with the s tandard method of second harmonic generation (SHG).
