We present a technique to measure the dielectric function of a material with femtosecond time resolution over a broad photon energy range. The absolute reflectivity is measured at two angles of incidence, and e(ω) is calculated by numerical inversio

We present a novel method for three-dimensional optical data storage that has submicrometer size resolution, provides a large contrast in index of refraction, and is applicable to a wide range of transparent materials. Bits are recorded by use of a 0

Submicron-diameter structures can be produced inside many transparent materials by tightly focused 100-fs laser pulses. The ultrafast energy deposition creates very high temperature and pressure inside the region, initiating a 'microexplosion'. Mater

We present experimentally determined values of the dielectric function of GaAs following femtosecond laser excitation. The data at photon energies of 2.2 and 4.4 eV show that the response of the dielectric function tot he excitation is dominate by ch

In our recent Letter1 a line of text was dropped in printing. On p. 2024 the beginning of the paragraph above Fig. 3 should read as follows: "Surprisingly, the 0.5-muJ pulse energy used in these microexplosions...".

We use a new broadband spectroscopic technique to measure ultrafast changes in the dielectric function of a material over the spectral range 1.5–3.5 eV following intense 70-fs laser excitation. The results reveal the nature of the phase transformat
