Femtosecond Laser Cutting
- Firstly, the duration of femtosecond laser pulses is extremely short, only a few femtoseconds, making them thousands of times shorter than the shortest pulses obtained using electronic methods, representing the shortest pulses achievable by humans under experimental conditions.
- Secondly, femtosecond lasers have extremely high instantaneous power, reaching trillions of watts, which is hundreds of times more than the total power generation of the entire world.
- Thirdly, femtosecond lasers can be focused into spatial regions smaller than the diameter of a hair, creating electromagnetic field intensities several times higher than the forces acting on electrons around atomic nuclei, many of which are extreme physical conditions that do not exist on Earth and cannot be obtained by other methods.
Due to the ultra-high peak power of femtosecond lasers, after focusing, the light intensity can reach the order of 10^22 watts per square centimeter. Such intensity far exceeds the Coulomb field of interaction within atoms, so femtosecond laser pulses can easily liberate electrons from atomic confinement, forming a plasma. For example, the Coulomb field strength of a hydrogen atom is 5×10^11 volts per meter, while a femtosecond laser pulse of 1 millijoule, after focusing, can reach the order of 10^12 volts per meter, allowing it to ionize hydrogen atoms.
Femtosecond laser cutting is a cutting-edge technique used in various industries, including manufacturing, electronics, and medical devices. It involves using an ultrafast laser, typically operating in the femtosecond (10^-15 seconds) range, to precisely cut materials with extremely high accuracy and minimal heat damage.
Applications of femtosecond laser cutting include microelectronics manufacturing, medical device fabrication, precision machining, and microfluidics, among others. It’s a cutting-edge technology that continues to push the boundaries of what’s possible in terms of precision manufacturing.

Why Use Femtosecond Laser Cutting For Extreme Precision?
Femtosecond laser cutting offers several advantages for achieving extreme precision in various applications:
- Ultrafast Pulses: Femtosecond lasers emit pulses of light with durations on the order of femtoseconds (10^-15 seconds). These ultrafast pulses enable precise material removal with minimal heat affected zones. As a result, the material can be cut or processed with extremely high spatial resolution and minimal damage to the surrounding areas.
- Non-linear Absorption: Femtosecond lasers operate in a regime where non-linear absorption processes dominate the interaction between the laser light and the material. This means that the laser energy is absorbed very efficiently and confined to a small volume, allowing for precise material removal even in transparent materials or materials that are traditionally difficult to process with conventional lasers.
- Cold Ablation: Due to the extremely short duration of femtosecond pulses, the energy deposited into the material occurs so rapidly that it effectively bypasses the thermal diffusion process. This phenomenon, known as “cold ablation,” minimizes the heat-affected zone and prevents thermal damage to the surrounding material, enabling high precision processing.
- Material Compatibility: Femtosecond lasers can process a wide range of materials, including metals, semiconductors, ceramics, polymers, and even biological tissues, with high precision. This versatility makes them valuable tools for applications ranging from microelectronics manufacturing to medical device fabrication.
- Intricate Geometries: The high precision and minimal heat affected zone of femtosecond laser processing enable the fabrication of intricate geometries and features with sub-micrometer accuracy. This makes femtosecond lasers suitable for applications requiring complex microstructures or fine details.
Overall, femtosecond laser processing offers unmatched precision, versatility, and control, making it an ideal choice for applications where extreme precision is paramount, such as microelectronics, biomedical devices, microfluidics, and photonics.
