Abstract

We demonstrate an extremely simple frequency-resolved optical-gating device (GRENOUILLE) capable of measuring pulses with spectra wider than 100 nm. Its nearly all-reflective geometry minimizes the material dispersion, allowing accurate measurement of pulses as short as 19 fs.

Compact GRENOUILLE geometries. Previous transmissive design for measuring pulses as short as 50 fs (top) and reflective GRENOUILLE design for measuring 20fs pulses (bottom).

Pulses measurable by use of GRENOUILLE with a 1.65-mm BBO crystal. The solid curve represents the (upper) limit set by the spectral resolution of the crystal (L×GVM=τp). The dashed curve represents the (lower) limit set by the GVD induced by the crystal [L/2GVD=τc]. Inset, theoretical FROG error versus pulse width due to crystal dispersion.
