Laser beauty devices (e.g., for hair removal, skin rejuvenation, and freckle removal) must comply with GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. Their core components are a medical laser of a specific wavelength (e.g., semiconductor laser, Nd:YAG laser) and its power supply, cooling, and control unit. The standards strictly limit the electromagnetic emissions generated by the laser power supply (especially pulsed lasers), while requiring precise energy/power control and a stable, interference-free cooling system (e.g., TEC or water cooling) to ensure the safety and effectiveness of the treatment.
