Lasers have in principle the capability to cut at the level of a single cell, the fundamental limit to minimally invasive procedures and restructuring biological tissues. To date, this limit has not been achieved due to collateral damage on the macro

Two-dimensional infrared photon-echo measurements of the OH stretching vibration in liquid H 2 O are performed at various temperatures. Spectral diffusion and resonant energy transfer occur on a time scale much shorter than the average hydrogen bond

A post processing algorithm called matrix-method deconvolution (MMD) was created that makes it possible to extract binary information from optical data storage beyond the limits of the Rayleigh criterion. The method was designed for use with an optic

2D-IR photon echo studies of the OH stretching vibration in pure liquid water are presented. At room temperature, a 50-fs decay of structural correlations is found. The temperature dependence of the vibrational dynamics is investigated.
