Lasartis (“The Art of Lasers”) is specialized in laser R&D and laser applications. The company provides consultancy services and fosters ideas and solutions in the field of advanced solid-state lasers. Lasartis has developed a proprietary design strategy to alleviate the problems associated with thermal lensing in diode-pumped solid-state lasers. Together with a proprietary frequency conversion schemes, this enables compact solid-state laser sources providing any wavelength in demand in the visible and ultraviolet spectral range. They are very suitable for replacing gas lasers in numerous applications, such as in lithography and writing fiber Bragg gratings.
