Microlithographic technological line for the production of diffraction optical structures on glass or crystalline laser optical elements. Main components: pattern generator, step-and-repeat camera, laser mask repair device, centrifuga, exposure setups, ovens, microscopes and other measuring tools. More than 14 years experience in the development and production of optical elements of ultrafast laser devices. Participation in the femtosecond laser research projects in the EU and USA.
Coating technological equipments for producing functional optical coatings for modification of surface reflectance and transmittance properties of laser optical elements. Most important instruments: design softwares of optical coatings (TFCalc, Essential Macleod, FilmStar), vacuum evaporation machines (BA510, BA710, Electrotech SL 10/20, Denton Integrity 36), spectrophotometers (Varian UV/VIS, Avantes), other quality control devices. The Denton Integrity 36 machine is capable to produce extreme high stable optical coatings with the ion-assited deposition technology without using substrate heating. Similar coating machine does not exist in Hungary or in neighbour countries.
Optical technological laboratory for production of laser optical elements from glasses and crystals. Most important technological devices: cutting, milling, grinding, lapping and polishing machines. Measuring devices for controlling the surface figures, goniometers for precision angle measurements, autocollimators. Long time experience in the development and production of optical elements of ultrafast optical devices.
State-of-the-art Ti:sapphire lasers. The laser pulses delivered have 4 mJ pulse energy, 35 fs pulse length, 1 kHz repetition rate with 790 nm central wavelength. Two autocorrelators belong to the laser system (one commercial and one home-built) with pulse characterization for 5 fs-15 ps laser pulses. These can also be individually used externally.
