07 Jul Scalable manufacturing for femtosecond lasers
Lithuanian laser company Litilit is building a production facility for femtosecond lasers in Vilnius. According to the company, the new factory is expected to reach an annual production capacity of up to 3,000 laser systems within the next few years. The goal is to enable industrial-scale manufacturing of femtosecond lasers and expand their use in production environments.
According to Litilit, the lack of cost-effective high-volume manufacturing remains one of the main barriers to the broader adoption of femtosecond laser technology. Conventional femtosecond lasers are often based on architectures originally developed for scientific applications. While these systems offer high performance, they are typically complex to assemble, difficult to automate, and require highly skilled personnel. Litilit, by contrast, has developed a laser architecture specifically designed for industrial manufacturing. A modular design, reduced component complexity, and a high degree of automation are intended to accelerate assembly, testing, and quality assurance.
The production facility is being built on a 4,000 m² site in Vilnius. It will include CNC metal machining as well as automated assembly and final testing areas for femtosecond lasers. Construction and fit-out are scheduled for completion in the fourth quarter of 2026. During the first year of operation, the company plans to manufacture up to 1,000 lasers. Annual production capacity is expected to increase to 3,000 systems in the following years. According to the company, the total investment amounts to approximately €6 million. The Vilnius facility is intended to serve as a model for additional manufacturing sites. Together with international partners, Litilit plans to replicate the production concept in other regions.
Patented laser architecture
The laser architecture is based on a development by co-founder Kęstutis Regelskis at the Center for Physical Sciences and Technology (FTMC) in Vilnius. It is designed to enable more compact, efficient, and industrially scalable femtosecond laser systems. According to the company, the architecture achieves an electrical-to-optical efficiency of approximately 20%. This reduces power consumption and cooling requirements while enabling reliable operation in industrial environments. At the same time, the laser systems are said to be compact, maintenance-free, and resistant to external disturbances.
