Beam propagation - Using diffractive
optical elements (DOEs), the intensity
distribution in the focus plane, as well as
along the beam axis, can be fitted to a specific application (e.g., creating…

…refractive element, there is no dependence on wavelength or
temperature. The distribution of energy does not have any other structure from
interference or feature separation. It is, however, important to closely match the incoming beam size to the polish
size of the optic (see Figure…

…features down to 10 nm, which is far below the diffraction limit. Achieving this
necessitated the development of highly
specialized excimers with grating-controlled line narrowing to minimize chromatic aberrations in the imaging optics.
A variety of other techniques, including

…single snapshot. CTIS uses a custom made diffractive optical element (DOE) as the wavelength selective element and requires post-capture computation to recover the image cube. Here we introduce volume holograms as a new type of wavelength selective element for spectral imaging. A volume hologram is…

Flat Top Options The flat top is a diverging optical element that provides a uniform intensity profile in the far field. It can be
imaged or offered simply as a diverging optical element.
Being cylinder based, it can be readily offered acting on only one axis…

…figure 3. Specifically, the profiler utilizes two knife
edges oriented at 90° to each other on a rotating drum,
together with a single element detector. As the drum
spins, the knife edges rapidly scan the beam in
orthogonal directions, and the transmitted light is
measured.…

…(Figure 3)
shows how four different light pulses are
all derived from the same broadband femtosecond source using a simple diffractive
optical element. (The fourth pulse is used
for heterodyne detection.)
This approach "guarantees a stable signal phase against environmental…
