Lithuania's LITILIT Raises €8 Million for Modular Femtosecond Laser System

Lithuania's LITILIT has secured an €8 million loan from the Lithuanian National Development Bank ILTE to develop a modular femtosecond laser system for industrial applications.

LITILIT is developing a femtosecond laser modular system (FEMODA) that is designed to create new laser applications in existing large-scale industries, such as the mass production of metal tools and the formation of specialized coatings on large surfaces.

FEMODA will target an average optical power of up to 1000 W, one of the highest in the modular industrial femtosecond system.

Nikolajus Gavrilinas, CEO of LITILIT, which recently broke ground on a large-scale femtosecond-laser facility in Vilnius, says that the new system will significantly expand the applications of femtosecond lasers.

“Currently, femtosecond lasers are mostly used in manufacturing high-value small parts. Our new laser system will open new applications in existing large-scale industries, such as the mass production of metal tools and the formation of specialized coatings on large surfaces, like aircraft or car bodies. It will also speed up current femtosecond laser applications, from consumer electronics to displays and chips,” Gavrilinas explains.

Femtosecond lasers use extremely short pulses that process materials without damaging the surrounding structure. This quality, also known as cold ablation, makes them indispensable in applications ranging from eye surgery and vascular stents to manufacturing computer chips and display screens.

However, Gavrilinas notes that the adoption of femtosecond laser systems is often limited by their heavy infrastructure, installation, and maintenance requirements.

For example, most existing systems use water cooling, which requires a dedicated water circulation and cleaning system that needs regular upkeep. They also rely on large, heavy optical modules that must sit on massive optical bases, along with sensitive optics to deliver the beam to the process location. Current systems also need to be kept in a stable-temperature environment.

“All this adds complexity and limits where lasers can be used. We’re building a system that combines the control electronics, optics, and cooling into a single industrial unit that can easily integrate into any factory,” Gavrilinas explains. “Our new modular platform will be less sensitive to temperature, humidity, and vibration, and its modules can be combined into a more powerful system. If one fails, only that module needs replacing - not the whole system.”

FEMODA will target an average optical power of up to 1000 W split across 10 to 20 separate beam channels, each capable of delivering femtosecond pulses to a different processing point on a production line.

LITILIT started developing the project in 2024, and this year received the €8 million loan from ILTE, the Lithuanian development bank. The company plans to invest €2 million of its own capital, with a total project amount of €10 million. Commercialization of the new laser system is planned for the second half of 2029.

FEMODA will advance LITILIT’s goal of making femtosecond laser systems scalable. Currently, one of the biggest barriers to adoption is that there is no way to produce high-power femtosecond laser systems at scale, as most traditional systems are complex to manufacture.

To address the scalability gap, in June LITILIT started developing a new high-capacity laser factory in Vilnius that will start operating this fall, targeting 3,000 femtosecond lasers a year.

LITILIT builds lasers based on a few patented inventions, made by LITILIT co-founders Kęstutis Regelskis, Nerijus Rusteika, and Gavrilinas, in close collaboration with the Center for Physical Sciences and Technology (FTMC) in Vilnius.

The financing will support the development of the technology, while the company is also building a new production facility in Vilnius with a planned annual capacity of 3,000 femtosecond lasers.

LITILIT’s new production facility will be a key component in the company’s goal of making femtosecond laser systems more accessible to a wider range of industries.
