JOURNAL FREE ACCESSRecent improvements of optical coatings for high power lasers are presented. A highly damage resistant coatings were developed by using the surface prepared and super-polished substrates. Furthermore, new antireflection coatings, which are chemically processed, are described. Shown are measured damage threshold data of those coatings for 1μm, 0.53μm and 0.355μm lasers.View full abstractDownload PDF (1195K) -

JOURNAL FREE ACCESSWe have developed a new type of photo hardening system for constructing 3-D models using an UV-laser and liquid photopolymer. In the system the surface of liquid photopolymer is exposed by laser scanning according to the sectional shape of 3-D pattern stored in the computer, and solidified photopolymer layers made thus are stacked successively to form the solid object. As the accuracy and speed of the shaping process are determined by the characteristics of the photopolymer, the experiments has done to obtain the most suitable composition of photopolymer. According to the results, the spatial accuracy and sensitivity are affected by the selection of oligomers, the density of the photoinitiator and mixing of some powder, and the plasticizer or the plastic powder should be used instead of the monomer to prevent the shrinkage of polymerization.View full abstractDownload PDF (959K) -

JOURNAL FREE ACCESSTechniques necessary for obtaining a high repetitive and long life operation of an electron beam pumped excimer laser were developed and studied. Using these techniques, the test facilities of the electron beam pumped KrF excimer laser with high repetitive operation was constructed. The laser output energy, repetition rate, and total efficiency are 6J, 4pps, and about 1.3%, respectively.View full abstractDownload PDF (671K) -
