GN tech to Introduce an Updated Line of Plasma Processing Units

Russian company GN tech and GN electronics are part of GN Group, which specializes in equipment and materials for microelectronics, photonics, optics, and biotechnology.

The main directions of GN tech are the development and production of plasma processing units for a wide range of applications, including photonics and optics. Plasma processing is widely used as a preparatory operation for surface cleaning from residual organic and inorganic contaminants, improvement of adhesion of thin-film coatings, quality of soldering and welding, and modification of surface properties.

At the stand, the most popular on the market mass-produced model of plasma treatment unit in low-frequency glow discharge plasma MPC LF in desktop version with the chamber volume of 12 liters will be presented and its operation will be demonstrated. The localization of components of the unit is 90%, which significantly reduces the production and service time.

The key trend of the company is to ensure delivery of equipment that provides results for each specific application. For this purpose preliminary test processes are carried out for testing of technological modes and recommendations are given for processing of customer’s products. Thus, for the last year more than 10 units of equipment were supplied to the leading Russian companies. The company specialists perform commissioning and testing of the units at the customer’s premises.

Plasma treatment plants have a wide model range and a wide choice of options, but if necessary, the company’s specialists can modify or design a non-standard plant to meet the specified requirements. In addition, it is possible to supply materials and blanks necessary for production of photonics, optics and microelectronics products.

GN tech invites its partners and clients to visit Stand No.FG072.

POLARUS to Present Ultrashort Pulse Fiber Lasers

POLARUS is an engineering and manufacturing company engaged in the production of ultrashort pulse fiber lasers and laser electronics.

Now the company product line has three picosecond laser sources with different average power up to 50 W and energy in impulse up to 20 mJ. In 2022 the company started development of a powerful laser with pulse duration <10 ps and energy in impulse up to 50 mJ. As additional options we can integrate a second harmonic generator and/or a pulse selector into lasers. POLARUS also adapts laser sources to individual customer tasks, if necessary.

Micromachining of various materials - ceramics, semiconductors, glass, plastics, films, etc. - can be performed on the company’s premises. Demonstration of lasers or performance of micromachining services is possible.

Institute of Laser and Welding Technologies to Present ILIST-M Robotic Direct Laser Growing Unit

The development of the Institute of Laser and Welding Technologies (ILIST) of Saint Petersburg State Marine Technical University – a robotic direct laser growing unit ILIST-M – was created to train students in technological centres of additive and related technologies at universities and enterprises of high-tech industries.

The ILIST-M direct laser growing unit was designed based on the advanced experience of the Institute of Laser and Welding Technologies of SMTU in the field of additive manufacturing of large-sized products from metal powders. The functionality of the machine provides the possibility of its further modernization.

On the one hand, it is a full-featured robotic process unit with controlled atmosphere, independent feeding of two materials, 7-axis kinematics and growing dimensions up to ø600 mm x h 400 mm. On the other hand, its small footprint, ease of use and low price make ILIST-M very attractive for research tasks, development of new technologies and materials, and contract manufacturing.

In 2022 the ILIST-M units were shipped to:

• LEONOV Moscow Region University of Technology in Korolev;
• Perm National Research Polytechnic University.

The development of the Institute of Laser and Welding Technologies (ILIST) of SMTU – a robotic unit for direct laser growing ILIST-M was awarded the title Laureate of LAS 2022 by the Laser Association in the category “Laser technologies in industry and power engineering”.

ILIST-M robotic direct laser growing unit was awarded a gold medal in the Best Innovative Project and Best Scientific and Technological Development 2022 competition in the Additive Technologies, 3D Printers, Metal Powder and Composite Materials for 3D Printers nomination.

As of today, the ILIST-M robotic unit for direct laser growing has no analogues in the domestic and world markets.

This unit will be demonstrated at stand No.FE100 of Saint Petersburg State Marine Technical University at the 17th International Specialized Exhibition for Laser, Optical and Optoelectronic Technologies – Photonics 2023.

Use MatchMaking to schedule a meeting with exhibitors today.

We look forward to seeing you at Photonics 2023 from March 28 through 31 in the Forum Pavilion of EXPOCENTRE Fairgrounds.
