Enhancement of Femtosecond Photon Echo Signals From an Inhomogeneously Broadened InAs Quantum Dot Ensemble Using Chirped Pulses. [PDF]
NanophotonicsChirped rephasing pulses satisfying adiabatic conditions enable robust adiabatic rapid passage across a THz‐broadened InAs quantum dot ensemble. This approach provides uniform population inversion and broadband rephasing, overcoming the limitations of transform‐limited excitation.

Alignment and study of prototypes of the Offner hyperspectrometer
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016 A prototype of the hyperspectrometer based on the Offner scheme has been tested. Drawings have been produced and the main mirror elements of the hyperspectrometer including diffraction grating on a convex spherical surface have been fabricated.

Modeling action of a hyperspectrometer based on the offner scheme within geometric optics
Computer Optics, 2014 We considered comparative modeling action of a hyperspectrometer based on the Offner scheme including prisms or a diffraction grating within the geometrical optics. It is shown that the use of a diffraction grating instead of a prism results in a more uniform spread of the spectral components of the dispersed image.

The study of the basic operating parameters of a hyperspectrometer based on the Offner scheme
Procedia Engineering, 2017 Abstract In this article, the comparing of mathematical modelling results of a hyperspectrometer based on the Offner’s scheme is considered. This modelling was carried on within geometric optics. The goal of this comparing was a confirmation of mathematical model correctness, which was developed.

A general hybrid radiation transport scheme for star formation simulations on an adaptive grid [PDF]
, 2014 Radiation feedback plays a crucial role in the process of star formation. In order to simulate the thermodynamic evolution of disks, filaments, and the molecular gas surrounding clusters of young stars, we require an efficient and accurate method for ...

Collection of selected papers of the II International Conference on Information Technology and Nanotechnology, 2016 We deal with the imaging spectrometer based on the Offner scheme. We define the optical transfer function of the imaging spectrometer based on the Offner scheme. We define the spectrum reconstruction error for red LED.

, 2011 One model for the origin of typical galactic star clusters such as the Orion Nebula Cluster (ONC) is that they form via the rapid, efficient collapse of a bound gas clump within a larger, gravitationally-unbound giant molecular cloud.
