Prospects of "Colorit" Technology of Color Laser Labeling "Colorit" technology of color laser labeling of metals, including precious ones, is presented, which allows to apply a color image without the use of pigments and dyes. The labeling technology is based on various optical effects: interference, diffraction of light and surface plasmon resonance. The images are of high resolution and have several degrees of protection, which makes it possible to use the method to protect products from falsification.

Very Short Pulsed High Diode Currents Generated by a Fast Laser Diod Driver For many laser applications, such as marking, additive manufacturing, material treatment, scientific research, etc. short pulses with high diode currents are required. For these applications diode currents of 100A … >200A with rise times of 20–50ns are often needed. In addition, the pulsesshall have a clear rectangular shape with short rise time, steep rising edges, no overshoot and no ripple. This article shows the physical restrictions and explains technical solutions how laser diode drivers can realize high diode currents with very short pulse lengths.
Photon Antenna "Russia-Taiwan" The description is given of the photon antenna "Russia-Taiwan", created on the basis of laser strainmeters of the classical type, established on two polygons of Russia and in Taiwan. Their technical capabilities for recording of various infrasonic disturbances of the Earth are estimated. Some results of processing experimental data are obtained, when carrying out complex tests of laser strainmeters.
Universal Multispectral Sight & Observation Device as The Means of Improving The FCS of Armament of Armored Force Vehicles (AAFV) Fiber Optic Devices & Technologies This article deals with the improvement of the fire control system of armored vehicles. It details designing of a stabilized multiunit and multichannel optical device of the sighting and observation system utilizing a single common entrance pupil. Some modifications of the basic system, e. g. a panoramic device are also reviewed in this article. Such approach allows the solution of numerous tasks – from minimization of the head parts allowing the optimization of the biplanar sighting line stabilization system up to the simultaneous operation in different spectral ranges, i. e. obtaining a complex panoramic image, which enhances the probability of detection and recognition of targets in adverse observation conditions.
Beat Length Measurement in Birefringence Optical Fibers Birefringence optical fibers (OF) appeared in 1978–1983 together with the technologies of thermoelastic inserts in the workpieces for drawing optical fibers. This article deals with two basic methods of measurement of embedded BOFs: spectral method and elastic twisting method. Three OFs types, drawn from the workpieces with embedded linear birefringence are taken as objects of study: HiBi or also PM- (polarization maintaining) fibers; fibers, drawn from the same workpieces, but with the rotation of the workpiece – spun-fiber; LoBi-fibers, which by the method are referred to as spun-fibers. The technique of measuring the beat length of the embedded BOFs is described in detail.
The paper analyzes two known methods for measuring the characteristics of an embedded birefringence of special optical fibers. The features of beat length measurement of the embedded birefringence for each method and different types of special fibers are shown. Advantages, disadvantages and limitations for each of the methods are pointed.
