The countries of Middle and Eastern Europe are, or will be in the nearest future, in the accession phase to join European Union (EU). These countries can be valuable members of expanding and market-oriented European scientific community. The most important is, both from the point of view of EU institutions and perspective of new member countries, support for integration of candidate countries in many fields such as science and technology, education, know-how technology transfer, and implementations. Such a modern branch of science and technology as "optoelectronics and lasers", especially their application in industry, metrology, medicine, environmental protection and cultural heritage could not be noticed at the beginning of the integration processes. For over ten years, the number of projects and undertakings, realised commonly by scientific organisations and enterprises from EU countries and candidate countries within the frame of the well-known programs as 5European Network th and 6th Framework Programs of EU, COST, PHARE, COPERNICUS and EUREKA Initiative has increased. One of the first initiatives for regular contacts, information transfer and organisation of scientific-research cooperation and applications of laser technologies was Austrian proposal and next EULASNET formation, "European Network of Lasers Application" (Since the end of 2005 it has been performed as E!2566 EUREKA Initiative in, so-called, Umbrella-Projects class in technology branch - Lasers).From 2006 it is continued as EULSNET II. According to the suggestion of German members, the EULASNET Experts Team proposed, in December 2001, that Poland should represent Middle-East European countries in EULASNET. The next stage of integration of scientific and industrial communities in Poland dealing with laser and optical technologies was the proposal to create Polish network - POLLASNET (at the end of 2001). It is coordinated by the Institute of Optoelectronics of the Military University of Technology (IOE MUT) as the institution that has been investigated and developed lasers and optoelectronic devices for many years. IOE MUT is also experienced in lasers application in many branches and has numerous contacts in Poland and European laser technology centers. Due to complementary integration of fundamental research, applied research and implementations of laser and optical technologies we hope of doing satisfactory common works of scientists, engineers, and businessmen as well as to create a centre with full access to library of laser and optical technologies and possibility of education and training of young engineers and scientists.
