Ekspla has unveiled the femtosecond laser FemtoLux 50, the latest addition to its award-winning ultrashort FemtoLux laser family of industrial-grade femtosecond lasers. New laser pushes the boundaries of reliability, versatility, and precision.
“FemtoLux 50 was engineered in response to our users’ needs,” says Lukas Rimgaila, Head of the OEM Program. “It delivers 50 W output power while featuring a unique military-grade waterless cooling system. This means space savings for the whole system as well as maintenance free 24/7/365 operation at comparatively high output power”
Power and precision for demanding applications
The femtosecond laser FemtoLux 50 is engineered to deliver an output power of 50 W at 1030 nm, facilitating exceptional performance for demanding micromachining processes. Combined with tunable pulse durations from sub-400 fs to 1 ps and repetition rates ranging from single-shot to 2 MHz, it seamlessly adapts to a wide range of industrial applications.
For enhanced versatility, users can fully leverage the ultrafast laser FemtoLux 50 through advanced burst mode options, including MHz, GHz, and combined MHz+GHz configurations, along with true Pulse-on-Demand (PoD) capability. These features ensure precise control over pulse timing and energy delivery, optimizing laser process parameters for efficient, high-quality machining at the workpiece.
Reliability redefined – FemtoLux with direct refrigerant cooling technology
The femtosecond laser FemtoLux 50 stands out in its power class with an innovative dry cooling system (DRC). By using this method, excess heat from the laser head is transferred via easily detachable cooling plate, which is cooled by a refrigerant agent directly. This system has already been employed in military applications, demonstrating “bulletproof” reliability – MTBF (mean time between failure) of the DRC system exceeds 90,000 hours. The laser cooling system can work 24/7/365 for more than 10 years without any downtime. The lifetime of the compressor in a DRC system is 3 to 5 times longer compared to water pumps.
Up to date the innovative Direct Refrigerant Cooling (DRC) system is the most efficient cooling method available. Its power consumption is half that of conventional water chillers and 8 times lower than TEC chillers.
As a result, femtosecond laser FemtoLux features output power up to 50 W, making it the only laser in its power class with such a compact footprint. Additionally, the FemtoLux delivers outstanding performance, including power stability < 0.5% RMS over 100 hours and superior beam quality with M² < 1.2.
Complimentary wavelengths for added flexibility
The femtosecond laser FemtoLux 50 is designed to excel in a wide range of manufacturing processes and materials. Depending on the task, it can be equipped with an optional harmonics module, enabling operation at 515 nm (20 W, >50 µJ) and 343 nm (10 W, >25 µJ). These additional wavelengths expand the user’s seamless control of precision, production time and applications.
User-friendly software & global support network
Although an advanced machinery, the industrial laser FemtoLux 50 runs on user-friendly software, backed by a team of dedicated service support as well as representatives from over 20 countries worldwide (USA, Germany, Japan, China, South Korea, and others) ensuring quick response times. With built-in sensors, it offers time-saving features and remote session capabilities to improve efficiency and convenience for users.
Micromachining applications
The ultrashort laser FemtoLux 50 offers solutions for glass, metal, polymer, and other materials. Numerous feasibility studies in renowned application laboratories show the laser’s applicability for various micromachining processes like semiconductor manufacturing and beyond, offering limitless potential.
