When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

Capillary high-harmonic generation (HHG) has the potential to be a very efficient source of soft X-rays because it offers an extended interaction length between the laser and the generating medium 9.

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...
