The company plans to complete major construction and outfitting work by the end of this year and achieve an annual production capacity of up to 3,000 lasers within a few years of commissioning.
Femtosecond lasers are among the most advanced tools for high-precision materials processing. Their extremely short light pulses enable highly accurate processing with minimal thermal impact, making them suitable for a wide range of applications, from semiconductor and advanced electronics manufacturing to medical procedures such as eye surgery.
According to Nikolajus Gavrilinas, co-founder and CEO of LITILIT, one of the biggest obstacles to the mass adoption of femtosecond lasers today is the lack of ways to manufacture them at the scale that industry will require.
“Traditionally, femtosecond laser architectures have evolved from scientific systems. They can offer high performance, but they are often complex to assemble, difficult to automate, and rely on highly skilled specialists. Our lasers are based on an architecture specifically designed for this purpose, with less complex components, a modular design, and a high level of automation. This allows us to organize assembly, testing, and quality control more quickly and efficiently,” explains Gavrilinas.
The factory will be located in Vilnius and will have a usable area of 4,000 square meters. It will include two main production areas: a state-of-the-art CNC metal machining workshop and robotic workshops for the assembly and testing of femtosecond lasers.
Major construction and fit-out work is scheduled to be completed in the last quarter of 2026. During its first year of operation, the factory is expected to produce up to 1,000 femtosecond lasers, with capacity increasing to 3,000 lasers annually in subsequent years. The total project value is projected to reach approximately six million euros.

Gavrilinas explains that the technological foundation underpinning LITILIT's approach to scalable production dates back to a 2014 discovery: a fundamentally new and patented method for generating ultrashort pulses. The company has been developing this technology since its founding in 2015 and, in 2022, raised 3.7 million euros from Taiwania Capital and Iron Wolf Capital to finance technological development, becoming the first company to receive investment from Taiwan's CEE fund, endowed with 200 million US dollars.
Based on the invention, made by LITILIT co-founder Kęstutis Regelskis at the Physical Sciences and Technology Centre (FTMC) in Vilnius, Lithuania, the company developed a patented laser architecture that makes it possible to create more efficient, compact, and industrially scalable femtosecond laser systems.
“Our architecture achieves a femtosecond electrical-optical efficiency of around 20%, a remarkable result for this sector. In practice, this translates into lower energy consumption, reduced cooling requirements, and reliable operation in industrial environments. This same architecture also allows us to manufacture compact and robust lasers that are maintenance-free and resistant to external disturbances,” says Gavrilinas.
The Vilnius factory is envisioned as the first step in a broader international expansion. LITILIT plans to replicate the model in other regions with international partners.
“Femtosecond lasers are becoming an essential tool for next-generation manufacturing, but their widespread adoption will depend on making the technology more accessible. With this factory, we are taking the first step toward a replicable global production model, and we are proud to begin this journey in Lithuania, a country with a strong tradition in laser science and engineering,” concludes Gavrilinas.
