A picosecond laser device is a medical aesthetic system utilizing ultra-short pulse laser technology (pulse duration: 450-750 picoseconds). Its core mechanism involves delivering high-peak-power laser energy (up to 1.5 GW/cm²) within trillionth-second bursts, enabling precise photomechanical targeting of dermal chromophores (melanin/tattoo ink particles) through laser-induced optical breakdown (LIOB) effects, while maintaining tissue-specific thermal relaxation times (TRT <10 ns) to minimize collateral thermal damage to surrounding tissues.

Picosecond lasers utilize wavelength-specific selectivity (e.g., 755nm, 532nm, 1064nm) to target chromophores such as melanin and hemoglobin through their distinct absorption profiles. By delivering ultra-short pulsed energy (picosecond-level, 1 ps = 10⁻¹² seconds), these lasers generate high-intensity photomechanical shockwaves that fragment pigment particles into submicron debris (<0.1 μm), which are then naturally eliminated via the body’s metabolic pathways (e.g., lymphatic system and macrophage phagocytosis)
