Simulating and optimizing compound refractive lens-based X
... with respect to N’. While attenuation by the lens means that CRLs practically operate within the first half-period (i.e. 0 N’ ), optical behavior differs markedly between the thin-lens limit (i.e. NT fN and correspondingly N’ 1) and the general thick lens case (i.e. all values of N’). This ...

... It is imperative to take the light’s polarisation into account when calculating the dipole force introduced in Chapter 2. The first reason is that the individual laser beam’s electric fields must be added as vectors. The resulting total electric field vector can then be used to calculate the intensi ...

... The system then acts as a source of radiation with photon energy E. Furthermore, since the photons are the result of stimulated emission, they all have the same frequency, phase, polarization, and direction. The resulting radiation is therefore very much more coherent than light from ordinary source ...
