Institute on Laser and Information Technologies (IPLIT RAN)

Russian Academy of Sciences

(IPLIT RAN) 

The IPLIT RAN activities involve the pursuance of fundamental and applied R&D works in the field of physics of lasers and laser radiation interaction with matter, as well as in development, production and application of laser technologies, equipment and devices in laser processing of materials, microtechnology, optics, industrial measurements and environmental monitoring, in chemistry and medicine.

In the field of laser technologies the processes and equipment are being developed for materials processing with laser: welding, cutting, heat treatment, microstructuring, fabrication of nanometer thin films, laser-computer rapid prototyping of 3D objects.

In the field of laser technics the first business is to develop high-power industrial CO2 lasers. The IPLIT RAN has the departments engaged in design and production of industrial lasers and laser units for processing materials, of optical, mechanical and electronic components for lasers. The special emphasis is placed on introduction of laser processing and its methods to industrial production. The challenging field for the IPLIT RAN activities is a through chain of works beginning from the study and optimization of processes and resulting in development, manufacturing, supply to the customer and service of laser processing units.

Laser Materials Processing

The use of laser radiation in the technology of processing and fabrication of products attracts an ever-growing attention of the world manufacturers owing to sharp improvement in accuracy, efficiency of processing and products quality; ecological cleanness of processes; saving of materials, energy resources and area; reduction of routine labor share.

A number of laser treatment processes has been developed and introduced by the IPLIT RAN, among them contour cutting of large-thickness metallic and non- metallic materials, welding of pipes, sheet metals and machine parts, heat treatment of surfaces (application of coatings, facing, hardening). These processes are used in car industry, wood- and metal-working industry, food industry.

To the recent technology of materials processing belongs laser rapid prototyping (modeling) of 3D objects from polymers by the computer image of the product. For this purpose at the IPLIT RAN an installation for laser stereolithography has been developed and the processes for manufacturing models of machine-building products (in car, aerospace, power industries), as well as complex objects (prostheses, models of human body organs) for medicine and criminalistics have been mastered. 

Industrial Lasers


Power TL-5M CO2 laser 
The industrial lasers developed and produced at the IPLIT RAN match all the regulations on reliability, stability and high technological quality of radiation which need to be met with the use of laser in industry. They include: 
  • a diversity of powerful (2, 4, 6 kW) multichannel cw CO2 lasers for heat treatment; 
  • a diversity of powerful (0.6, 1.2, 1.5, 2.5 kW) cw fast-transverse-flow CO2 lasers for cutting metallic and non-metallic materials; 
  • a diversity of high-power (5, 10, 15 kW) industrial cw CO2 lasers for welding and cutting of large-thickness metallic products; 
  • pulse-periodical CO2 laser of 1.5 kW power for punching holes and engraving; 
  • pulse-periodical industrial Nd:YAG lasers of 0.3 and 0.6 kW power for precision cutting, welding and punching. 

At the IPLITL RAN the optical components (mirrors, windows, lenses, beam splitters, polarizers) and units for high-power (up to 10 kW) CO2 lasers, systems for beam transportation and optico-technological heads for laser processing of materials have been developed and are being produced.

Laser Microtechnologies

Alongside with high-power laser technology of materials processing, the application of lasers in thin-film microtechnologies is being developed at the IPLIT RAN for the tasks of electronics and instrument engineering. The researchers of the IPLIT RAN have elaborated the theoretical backgrounds and developed the technology of laser-plasma deposition and direct laser writing of film microstructures from dielectrics, metals and semiconductors which are required in fabrication of microcircuits and chips with spatial resolution at the level of 0.3 micron.

The laser microtechnology covers also the methods and devices under development at the IPLIT RAN for diagnostics of undersurface microdefects by the use of laser probing; early diagnostics of diseases by microanalysis of breathed out gases; express-analysis of hazardous chemical and mechanical microimpurities in the atmosphere by methods of laser spectroscopy.

Laser Biomedicine

In cooperation with a number of research institutes, universities and medical centers of Russia and the Western countries, the IPLIT RAN is engaged in investigation and development of new applications of lasers in medicine, as well as in the study of fundamental mechanisms of laser radiation interaction with biomolecules and biotissue.

The laser-equipped scientific and practical medical rooms have been set up for diagnostics and cure of diseases (movement and support organs, gynecology, stomatology, traumatology, cardiology).
 
The installations for laser surgery, therapy have been developed; fiberoptical devices have been designed and are under production for the purpose of laser medicine. A medical installation for myocardium revascularization has been developed for the first time in Russia and Europe. The pioneer methods of lasers application, including laser formation of cartilagenous tissue, laser deposition of biocompatible coatings on implants are being developed.
