Partially coherent ultrafast spectrography
Modern ultrafast metrology relies on the postulate that the pulse to be measured is fully coherent, that is, that it can be completely described by its spectrum and spectral phase. However, synthesizing fully coherent pulses is not always possible in practice, especially in the domain of emerging ultrashort X-ray sources where temporal metrology is strongly needed. Here we demonstrate how frequ...
متن کاملExtracting coherent modes from partially coherent wavefields.
A method for numerically recovering the coherent modes and their occupancies from a known mutual optical intensity function is described. As an example, the technique is applied to previously published experimental data from an x-ray undulator source. The data are found to be described by three coherent modes, and the functional forms and relative occupancies of these modes are recovered.
متن کاملUltrafast nanoplasmonics under coherent control
Recently, there has been an increased attention and rapid development in the field of nanoscale collective electronic dynamics on surfaces of metal nanostructures, which is due to excitations called surface plasmons (SPs). This field, known as nanoplasmonics, is very promising for such applications as the next generation optoelectronics, computations and information storage on the nanoscale, ul...
متن کاملSelf-steering partially coherent beams
We introduce a class of shape-invariant partially coherent beams with a moving guiding center which we term self-steering partially coherent beams. The guiding center of each such beam evolves along a straight line trajectory which can be engineered to make any angle with the x-axis. We show that the straight line trajectory of the guiding center is the only option in free space due to the line...
متن کاملFocusing of spatially inhomogeneous partially coherent, partially polarized electromagnetic fields.
We report a general framework capable of describing the focusing of electromagnetic waves with spatially varying coherence and polarization properties in optical systems of arbitrary numerical aperture and Fresnel number. We also investigate the reduction of the dimensionality of the requisite integrals by use of a coherent mode expansion. We find that coherent mode expansions treating each com...
