Abstract We describe a research project carried out with group of undergraduate physics students and aimed at exploring the use neural network to study classical problem in wave optics whose analytical solution is well known: diffraction light by straight edge an opaque semi-infinite screen. Through this exposure machine learning, were able appreciate basic steps involved machine-learning proce...

Different intermittent curing methods were conducted for pulsed laser induced photopolymerization reactions in a TMPTA acrylic system. Two methods of curing were compared, named grouped pulses impingement (GPI) and consecutively pulsed curing (CPC), respectively, in which the total number of the curing pulses were kept same. In GPI, a prominent light diffraction effect was observed in the post ...

Ionization of atoms and molecules in laser fields can lead to various interesting interference structures the photoelectron spectrum. For case a superintense extreme ultraviolet pulse, we identify novel petal-like structure electron momentum distribution along direction field propagation. We show that this is quite general be attributed Fresnel diffraction electronic wave packet by nucleus. Our...

We present a new prior for phase retrieval from X-ray Fresnel diffraction patterns. Fresnel diffraction patterns are achieved by letting a highly coherent X-ray beam propagate in free space after interaction with an object. Previously, either homogeneous or multi-material object assumptions have been used. The advantage of the homogeneous object assumption is that the prior can be introduced in...
