Cutting-Edge Femtosecond Technology for Industrial Demands
The 10W Femtosecond Laser Source from LitiLit is a high-performance ultrafast laser solution engineered for demanding industrial and scientific applications. Designed by a pioneer in femtosecond laser technology, this laser delivers exceptional performance, long-term reliability, and operational flexibility for applications such as precision material processing, semiconductor manufacturing, and advanced research. In India, United Spectrum Instruments is the official distributor, ensuring local availability, technical support, and seamless adoption of LitiLit’s femtosecond laser systems.
Innovative Passively-Cooled Design and Stability
This 10W femtosecond laser source is an innovative, passively-cooled laser head designed to ensure extreme stability across all optical parameters. This rugged mechanical construction maintains precise pulse duration, beam pointing, and power stability even in challenging environments. Built to withstand industrial wear and tear, the laser’s design eliminates the need for complex water-cooling systems, reducing maintenance and footprint. Furthermore, the built-in second harmonics (SH) module provides essential wavelength extension (515 nm), broadening the range of compatible materials and processing capabilities.
Wavelength Extension for Versatile Ultrafast Processing
To further enhance application flexibility, the laser includes a built-in second-harmonic (SH) generation module, enabling wavelength extension beyond the fundamental output. This capability supports a broader range of laser–material interactions, expanding its suitability for micromachining, thin-film processing, and advanced manufacturing processes. Combining high stability, robust design, and wavelength versatility, the 10W femtosecond laser source is an ideal choice for users seeking precision, durability, and scalability in ultrafast laser systems.
Understanding 10W Femtosecond Laser Source
Ultrashort pulse lasers, particularly in the femtosecond regime (<300 fs), deliver extremely high peak powers while minimizing thermal diffusion. This makes the 10W Femtosecond Laser Source exceptionally well-suited for applications that demand precision, minimal heat-affected zones (HAZ), and clean processing. This air-cooled femtosecond laser combines compact design, robust construction, and ultrafast pulse technology to deliver high stability and industrial-grade reliability. The integrated second-harmonic (SH) module extends the wavelength to 515 nm, broadening its use in diverse material-processing tasks.
