Photomasks are the backbone of microfabrication industries. Currently they are fabricated by a lithographic process, which is very expensive and time consuming since it is a multi-step process. These issues can be addressed by fabricating photomasks by direct femtosecond laser writing, which is...

It is shown that the forward-backward (FB) version of the semiclassical (SC) initial value representation (IVR) is able to describe quantum interference/coherence (i.e., diffraction) of particles transmitted by a two-slit potential. (In contrast, the linearized approximation to the SC-IVR, which...

Femtosecond laser pulses are useful for laser microfabrication through multiphoton absorption. However, it is difficult to create interference of femtosecond pulses for the fabrication of periodic structures. In this letter, we report the fabrication of two-dimensional periodic structures by...

A new 3D microfabrication method has been developed, which uses only a single femtosecond laser pulse and a hologram. For the microfabrication inside transparent materials, the optical axial elongation of the fabricated structure is a major problem that has thus far limited design flexibility,...

We make predictions for the diffractive longitudinal structure function FLD to be measured at HERA, based on the DGLAP fits of diffractive parton distributions with an additional twist-4 term. This term describes the diffractive qÇ production from longitudinal photons. The twist-4...
