Industrial 3D Printers – Expensive Toys or realistic means to modernist engineering industry in Russia? Additive technologies are the topic of the day discussed at government meetings. The proposed article dispels myths about the possibilities of additive technologies. Problems of the additive technologies machines users are discussed.
Contrasting the photodigm DBR laser diode architecture with competing DFB designs DFB lasers and DBR lasers share many of the same characteristics of narrow linewidth and tunability. Whereas the DBR is fabricated on single growth epi, the DFB requires that the grating be buried under a high index layer, epitaxially regrown over the grating, inorder to form the waveguide. This fabrication difference leads to critical distinctions between the operational characteristics of these two architectures.
Laser Beam Intensity Profile Shapers It often happens that the effectiveness of a particular technology can be significantly improved by converting the intensity distribution of the laser beam. This is one of the reasons for the growing interest in the methods of radiation formation.
Phase Portraits of Periodic Planar Waveguides To solve the problem of efficient radiation input into a fiber, especially when it is performed on a single substrate with an integrated circuit, it is important to investigate the propagation of light inside the waveguide. The article proposes a method for analyzing the behavior of light rays in planar fibers based on the construction of a phase portrait of the state of a dynamic system. The phase portrait contains rich information on the behavior of light rays in a waveguide resonator.
Photonics, World Of Lasers & Optics – 2018: Innovations In Photonics Industry And Technical Optics Hardware Components Increasing sales of lasers on global market are indicative of the fact that laser technologies are finding new niches for their use. There is growth in demand for various purposes: high-accuracy machining of materials, high-accuracy metrology, detecting objects, detecting gravitation waves, laser medicine.
130th Anniversary of The First Photoelement The first microbolometer in Russia capable of working in two IR spectres (3–5 μm and 8–14 μm) is about to be commercialized. Microbolometers don’t need cooling, that’s why they have been highly esteemed by television engineering specialists.
