Scientific Description
The mission of the Wigner Femtosecond Laser Laboratory is the local development of femtosecond laser technology and related optical manufacturing technology. Femtolab provides accessible results in these fields for a broad audience in research and industry. The tasks are the development of femtosecond lasers and laser systems, their application in fundamental and applied research, the precision fabrication of large-aperture femtosecond optical components (dielectric and metal mirrors, gratings etc.), the testing of these optics in lasers and the development and testing of optical components for the Hungarian Extreme Light Infrastructure (ELI) project. The network consists of a femtosecond laser laboratory, a precision optical technological workshop, an optical thin film laboratory and a microtechnological laboratory.

Sample production

Sample production and small scale production of functional optical coatings for the needs of laser physical research

Usage of pulse diagnostic equipment

Femtosecond light source for fundamental and applied research experiments as well as for the development and usage of pulse diagnostic equipment

Preparation of surface microstructures

Preparation of surface microstructures, quality control of surface microstructures, development and small scale production of optical diffraction gratings

Microtechnology laboratory

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.

Optical thin film laboratory

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.

Precision optical processing workshop for laser optical elements

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.

Femtosecond Laser Laboratory

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.
