The company will demonstrate the capabilities of robotic laser systems that can be used to restore worn and damaged parts to factory parameters. Such stations are effective for maintenance of industrial equipment at large production facilities, for example, in the oil and gas or mining industries. The use of laser technologies allows to increase the service life of parts and mechanisms and improve their operational properties.

Robotic laser systems are characterised by high accuracy and speed of operation, as well as their wide range of functions. Types of tasks that can be solved with a robotic laser system from IRS Laser Tech:

• Parts are restored using powder, wire or hybrid laser cladding of additive materials characterised by high wear resistance. The technology makes it possible to restore damaged rolling shafts, hydraulic cylinder rods, rotors of electric motors and generators, thus avoiding the need to replace expensive parts, which is especially important in the current problems with the supply of new foreign-made spare parts.
• Laser hardening of metal surface provides increased wear resistance, strength, corrosion resistance, which in turn adapts parts of industrial mechanisms to increased load.
• Laser cleaning of parts allows to quickly remove oil, rust, soot, oxidation and other contaminants that appear in the course of operation and have a destructive effect on metal from mechanisms of any configuration and shape.
• Laser welding allows to weld different types of metals and alloys, making any kind of joints: butt, lap, angle, T-joint, and end joints. The speed of robotised laser welding is 3-10 times faster than traditional welding!

IRS Laser Tech offers both the services of parts remanufacturing and heat-hardening, and the supply and integration of robotic laser stations to enterprises for use within their own production processes. At the stand, the company's experts will advise everyone on the practical application of renovation laser technologies in industry.

At Photonics. World of Lasers and Optics 2024, the Zelenograd Nanotechnology Center will show a state-of-the-art photonic component base developed and manufactured entirely in Russia, providing high-speed and secure data transmission in a fibre-optic network.

The Zelenograd Nanotechnology Centre will demonstrate a photonic integrated circuit crystal and a module for multiplexing systems – Coarse Wavelength Division Multiplexing (CWDM) – at its stand FA044. Two modifications of the CWDM crystal will be demonstrated at the exhibition: five- and seven-channel, i.e. 5 or 7 information channels are transmitted over the optical fibre.

CWDM devices are designed for city networks and 5/6G telecom systems, IP telephony, data processing and storage centres, and the Internet of Things. The technology extends the service life of fibre-optic networks, and the increased frequency distance between channels leads to reduced wear and tear and cost of components and all equipment.

“Today, about 40% of the electronics produced worldwide are created using a photonic component base. This is a strategically important area. The Zelenograd Nanotechnology Centre contributes to it. The company aims at increasing production volume and expanding market share. We have managed to create a unique for Russia infrastructure for development and production of photonic component base and modules based on it. The chosen vector will allow us to become a leader of the Russian photonics market, a reliable partner and supplier of photonic component base for Russian technology companies in the field of telecom, unmanned technologies, robotics, machine tools, and at the same time to ensure the technological sovereignty of this country,” said Anatoly Kovalev, Director General at the Zelenograd Nanotechnology Center.

In addition, the Zelenograd Nanotechnology Centre shows photonic delay line integrated circuits that are designed for quantum key verification systems. The delay line is designed in a planar waveguide structure together with a Russian developer of quantum cryptography equipment.

Optical multiplexers are used to combine signals coming to the input of a fibre optic line. If the number of channels is less than 16, the simplest types of multiplexers based on thin-film filters (TFF) are used, and if the number of channels is more than 16, integral-optical multiplexers based on arrayed waveguide gratings (AWG) are used. An AWG multiplexer consists of an array of planar waveguides and two taps located at the input and output. The lengths of neighbouring waveguides differ by the same amount. At the input, all waveguides are illuminated equally, so the phases of the light waves at the output of the waveguides also differ by the same amount.

Photonics. World of Lasers and Optics 2024 takes place from 26 to 29 March 2024 at EXPOCENTRE Fairgrounds. The Zelenograd Nanotechnology Center will hold the Conference on Photonic Integrated Circuits within the show’s conference programme – the 12th Congress of the Photonics Technology Platform – on March 27. The speakers will be experts from various industry enterprises, including members of the new Photonic Integrated Circuits Working Group. The conference will discuss issues of quantum cryptography, new materials in the field of photonics and the application of photonic technologies to enhance neural networks.

Giricond Research Institute has developed infrared filters for military and civilian video systems to replace imported ones

Optical interference filters (FOI-1) allow to obtain images in the spectral range from 2 to 20 microns and can be used in various fields, including thermal imaging equipment, gas sensors, devices for fire safety and meteorology. The products are able to replace foreign analogues of Swedish, American and British manufacturers. The range mastered by the company includes short-wave and long-wave blockers, as well as narrowband and bandpass filters.

The filters retain their operational properties for 15 years at operation in the temperature regime from -60 to 70 C and relative humidity of 98%. The products meet the requirements of the Russian Ministry of Defence and can be used not only in civilian video surveillance and control systems, but also as part of special-purpose complexes.

The company’s experts will answer all your questions at stand FB060.

We are looking forward to seeing you at Photonics. World of Lasers and Optics 2024 in Pavilion Forum of EXPOCENTRE Fairgrounds, Moscow, Russia, on 26–29 March 2024.
