Calculation of vectorial three-dimensional transfer
... At large focusing angles the vectorial nature of the electromagnetic field becomes increasingly significant and the accuracy of the scalar description is compromised.6–8 In addition, many applications involve imaging of anisotropic samples such as a distribution of oriented dipoles in single-molecul ...

Raman microscopy in an electron microscope: combining chemical
... By applying a quite powerful laser system and a large number of molecules in the excitation volume high intensities of Raman scattering can be obtained. In the following chapters we will speak about micro-Raman set up’s which have usually a compact sized laser source. Therefore, large laser excitati ...

Second Harmonic Generation Technique and its Applications
... n = n2ω −nω = 0 (phase matching). In that case both bound and free waves propagate with the same velocity. In Section 4.1 we will describe how such situation can be realized. Although at ε ⇒ 0 we could expect a singularity in Eq. (11), this is not the case, as at the same time ϕ ⇒ 0 and, conseque ...

FABRICATION OF MICROFLUIDIC STRUCTURES BY LASER
... an array of lithographically defined grating couplers on a chip now has 6 degrees of freedom – three translation axes, and rotation about those axes. If we can build a system to mechanically constrain some of these degrees of freedom, and automatically align the others, we can align a chip to a fibe ...
