Femtosecond laser
Femtosecond laser technology has emerged as a game-changer in the world of laser technology. It is a type of laser that emits ultrashort pulses of light, typically of the order of femtoseconds (one quadrillionth of a second). These lasers are known for their ultrafast and precise performance, making them valuable in various scientific, medical, and industrial applications.
How does a femtosecond laser work?
Femtosecond lasers operate by generating pulses of light with durations in the femtosecond (10-15 sec) range. This is achieved through techniques such as mode-locking, where the laser cavity is designed to produce ultrashort pulses by synchronizing the phases of different longitudinal modes of the laser.

The ability of femtosecond lasers to operate in three dimensions makes them ideal for 3D milling and polishing applications. By precisely removing material layer by layer, these lasers can create complex 3D geometries with sub-micron accuracy. This capability is leveraged in the production of molds, dies, and prototypes, where intricate designs and smooth surface finishes are essential.
Micro & Nano Drilling
In the realm of micro and Nano manufacturing, femtosecond lasers play a vital role in drilling ultra-small holes with diameters ranging from micrometers to nanometers. This capability is utilized in manufacturing microfluidic devices, aerospace components with microscale features, and medical devices such as drug delivery systems and bio-sensors. The precise control offered by femtosecond lasers ensures repeatability and accuracy in these demanding applications.
Glass to Glass Welding
Femtosecond lasers enable bonding or welding of glass-to-glass interfaces with high precision and strength. This technique, known as glass welding, finds applications in the production of optical components, microfluidic devices, and hermetically sealed packages for electronics. The ability to create seamless bonds without introducing additional materials or adhesives is a significant advantage in terms of reliability and performance.
3D Additive Manufacturing
Femtosecond lasers have also made significant strides in the field of additive manufacturing, where complex 3D structures are built layer by layer. By using femtosecond laser-induced forward transfer (FLIFT) or two-photon polymerization (2PP) techniques, manufacturers can create microscale and nanoscale structures with high resolution and detail. This capability opens new possibilities in producing miniaturized components, micro-optics, and custom-designed structures for various applications.
