Techniques of ultrafast spectroscopy


E. N. Glezer. 1996. “Techniques of ultrafast spectroscopy.” In Spectroscopy and Dynamics of Collective Excitations in Solids, edited by B. Di Bartolo, Pp. 375–416. Plenum. Publisher's Version


This chapter begins with a general introduction to ultrafast spectroscopy, considers the limits of time and frequency resolution, and reviews the linear and nonlinear propagation of light pulses in a dispersive medium. Next, the basic elements of ultrashort laser pulse generation are described, including gain medium requirements, mode-locking mechanisms, compensation for group velocity dispersion, and pulse amplification. The last section deals with the measurement of ultrashort pulses, including joint time-frequency techniques, and also describes pulse-shaping in the frequency domain.
