Light in a vacuum has a frequency of {eq}5.0\times 10^{15} {/eq} Hz. What is the wavelength of light in a vacuum? a. {eq}1.7\times 10^{7} {/eq} m b. 60 nm c. 600 nm d. 30 nm Light: Light is an electroma...
In one aspect, a frequency-tunable light source (10) includes a resonant optical cavity (12), an optical gain medium (18), an optical mode filter (20), and a mode frequency tuner (22). The resonant optical cavity (12) supports oscillation of light in at least one longitudinal mode ...
A general frequency-dependent dispersion relation of the speed of light in different mediums (vacuum, insulator, plasma) is deduced based on the Proca equations. Several recent astronomical observations of the pulsars are used to set the limits on the photon rest mass by this method and several...
Here, we show that arbitrary linear transformations can be performed directly in the synthetic space spanned by the different frequency modes carried by a single physical waveguide. We use gradient-based inverse design to automate the process of designing the linear transformations, and demonstrate tha...

The two lenses combined with the phase-shift filter performs a adjustment of the mask image in the spatial frequency domain, projecting an image that is equivalent to the differentiation of the light intensity of the mask image, thereby reproducing a sharper defined mask pattern on the wafer....

Here, we use these techniques and present a new set of experimental and theoretical studies of harmonics 7 to 13, generated below and near the ionization threshold in xenon gas with an intense 1,070 nm laser pulse. These harmonic orders are of great interest for the development of vacuum-...
