Core Technology: Why Ultrafast Matters
The Revolution of "Cold Processing"
Traditional laser processing relies on thermal energy to melt or vaporize material, often leaving behind heat-affected zones (HAZ), micro-cracks, and debris. Ultrafast lasers (Femtosecond & Picosecond) operate on a different physical principle. By delivering energy in incredibly short pulses, the material is ablated before heat can conduct to the surrounding area.
Physical Mechanism of Cold Ablation
Ultrafast laser processing, particularly with femtosecond and picosecond pulses, achieves what is known as "cold ablation". This phenomenon is attributed to the extremely short pulse duration, typically in the range of femtoseconds (10^-15 s) to picoseconds (10^-12 s). When these ultrashort pulses interact with a material, the photon energy is absorbed by electrons, leading to rapid electron excitation. The energy transfer from electrons to the lattice (phonons) occurs on a timescale longer than the pulse duration. Consequently, the material is removed through processes like multiphoton absorption and plasma formation before significant thermal diffusion can occur into the surrounding material. This minimizes the heat-affected zone (HAZ) and prevents thermal damage, a critical advantage over conventional laser processing.
