Abstract Background Age is one of the most important risk factors for developing breast cancer. However, age-related changes in normal breast tissue that potentially lead to breast cancer are incompletely understood. Quantifying tissue-level DNA meth

We measure the third-order nonlinear optical response of various dielectrics and semiconductors using the spectrally resolved two-beam coupling method at 2.3 µm, 3.5 µm, 4.5 µm, and 8.3 µm. These materials include fused silica, sapphire, calcium

We report the first measurements of the nonlinear response of phonon polaritons near 7.3 µm in atomically thin layers of hexagonal boron nitride. We observe the phonon-enhanced third harmonic and the transient phonon-induced second harmonic.

We measure the nonlinear refractive index n2, two-photon absorption coefficient, and hot-electron nonlinearity of gated graphene in the mid-IR regime. Our results show that both the magnitude and sign of n2 can be voltage-controlled.

We introduce an approach to engineer defects in hBN using intense pulses resonant with phonons at 7.3 pm. Such defects are highly subwavelength (< 30 nm) with an alignment sensitive to the polarization.

We show that the ellipticity dependence of harmonic generation from graphene is a function of its Fermi energy. This allows for the yield and output ellipticity to be readily tuned via electrostatic gating.

We show theoretically and demonstrate experimentally that collapsing elliptically polarized laser beams experience a nonlinear ellipse rotation that is highly sensitive to small fluctuations in the input power. For arbitrarily small fluctuations in t

We predict that elliptically polarized beams undergoing multiple collapsing-defocusing cycles experience a loss of polarization and demonstrate this experimentally by measuring a large increase in fluctuations of nonlinear ellipse rotations for pulse

Ionization occurs ubiquitously in intense laser-matter interaction and often leads to rapid decrease in laser intensity via plasma defocusing, shortening the effective interaction length of desired high-field processes. Refocusing of pulses may compe
