UAB MGF "Šviesos konversija" (known as Light Conversion on international market)  is the world leading manufacturer of continuously wavelength tunable ultrafast light sources based on TOPAS series of optical parametric amplifiers and frequency mixers. Established in 1994, as a spin-off from Vilnius University Laser Research Center, the company has built its strength on profound knowledge in the field of optical parametric generation and amplification accumulated by its people in general and its leader Dr. Romualdas Danielius in particular. 

High qualification and experience of its specialists together with an early vision that ultrafast sources of tunable wavelength soon be a common extension of femtosecond and picosecond Ti:sapphire amplifiers allowed Light Conversion to offer the world market the most professional and innovative approach to development of commercial ultrafast optical parametric generators and amplifiers. Since very start in production and many years ahead of its competitors, Light Conversion "TOPAS" series of parametric amplifiers has offered numerous pioneering solutions such as very compact, non breadboard based construction, computer controlled wavelength tuning and vast flexibility in terms of input energy and pulse duration. Since then over 1000 of "TOPAS" series systems, many of those tailored to meet very specific customer requirements, have been installed worldwide.  

Starting from 2007 Light Conversion has introduced it’s new development – PHAROS ultra short laser system. Featuring market-leading femtosecond pulse output parameters along with robust, industrial design PHAROS has gained significant attention of industrial and scientific customers. Primary applications of Light Conversion femtosecond laser are in material processing and micromachining. However coupled with ORPHEUS parametric amplifiers PHAROS becomes an attractive laser source for ultrafast spectroscopy applications.
