Soothing the wearied sight,
That cannot bear the solar beam,
With soft undazzling light?

On me would cease to beam;
Their rays, with present, perfect warmth,
Upon my heart would gleam.

All things that there shall dwell,
With so much glory, light, and bliss,
That none can think or tell.

Which cheers us in our lonely bark,
Upon times dark, relentless stream.

From any casement creeping out.
The swift rain on the patient night
Swept, and anon would great winds shout.

In science:

We see that the unitarity (2.27) of the beam-splitter matrix B is not a coincidence — it follows from the conservation of the commutation relation (2.8) in light scattering.
Quantum Physics of Simple Optical Instruments
The Jordan-Schwinger representation (4.6) serves not only to characterize the polarization of quantum light, the representation provides also the theoretical tools to describe the effect of polarizers or of any beam splitter in general.
Quantum Physics of Simple Optical Instruments
In fact, many absorbers are first of all scatterers, but it is quite remarkable that we can sum up the multitude of scattered light modes in just one outgoing mode of a fictitious beam splitter.
Quantum Physics of Simple Optical Instruments
Active devices require external energy sources, often provided by other light beams.

The crystals downconvert pump light into entangled beams in all directions.

The deformation of a constant intensity circle in a light beam centered at r0 by each of these terms is also shown here.
Observations of cluster substructure using weakly lensed sextupole moments
Since the native states of proteins are usually rich of motifs like α–helices and β –sheets, and such motifs are able to rotate the polarization of an incident light beam, it is possible to measure the degree of formation of the motifs and approximate this with the degree of folding.
Simple models of protein folding and of non--conventional drug design
We investigate the coupling efficiency of parametric downconversion light (PDC) into single and multi-mode optical fibers as a function of the pump beam diameter, crystal length and walk-off.
Measurement of Coupling PDC photon sources with single-mode and multimode optical fibers
The first QWR type (optimum b ≡ bm = 0.041, 80.5 MHz) is very similar to existing QWRs in use at INFN-Legnaro (b is the beam velocity divided by the speed of light).
Niobium Quarter-Wave Resonator Development for The Rare Isotope Accelerator
Weyl succeeded in completing this program starting from the experimental fact that the speed of light is a constant c around any closed polygonal path (the light beam can be reflected over suitable mirrors so as to travel over the closed polygon).
Simultaneity in special and general relativity
Moreover, assume that the first light beam once reached B is there reflected to C , then again to B and finally A.

Comparison of the output light cone of a ‘standard’ fiber with NA=0.22 (right) to a fiber with ‘tuned’ NA of 0.16 (left). Given an input beam of f/3.5 (NA=0.14), the standard fiber shows an extended halo that is outside the nominal beam and may cause scattered light within the spectrograph.

A light source emits photons which pass through a beam splitter.
Quantum random number generator
One may think of a beam splitter as a partly silvered mirror. A mode of light enters the beam splitter on each of the mirror’s two faces.
