title: Extremely simple device for measuring 1.5-microm ultrashort laser pulses.
abstract: We have demonstrated an experimentally very simple and sensitive GRENOUILLE device for measuring the intensity and phase vs. time and spatio-temporal distortions of 100-fs to few-ps 1.5-microm pulses using the nonlinear-optical crystal Proustite. We show that the dispersive and nonlinear-optical characteristics of Proustite are critical for achieving very simple and reliable measurements of such pulses from fiber lasers and optical parametric amplifiers.
