Characterization of a liquid-crystal ultrafast pulse shaper for ultra-broadband applications

Research output: Contribution to journalArticle

Abstract

By combining broadband common-path spectral interferometry with an iterative fitting algorithm the phase response of a liquid-crystal spatial light modulator has been characterized from 400 to 770 nm, equivalent to a frequency bandwidth of 0.36 PHz. The resulting calibration not only maps the response of the device as a function of wavelength and voltage, but also provides sufficient information to recover the thickness of the liquid-crystal cell and the wavelength dependent refractive index of the liquid-crystal. The technique has applications in amplitude and phase shaping of pulses from broadband supercontinuum and optical parametric oscillator/amplifier sources. (C) 2014 Elsevier B.V. All rights reserved.
