Which EMC (electromagnetic compatibility) components are helpful for the design and modification of laser beauty devices?

EMC specifications for laser beauty devices can refer to those for therapeutic laser devices, but may have lower power. The laser driver power supply (especially the switching power supply section) needs a built-in high-performance EMI filter. The energy storage capacitor and switch that generate the laser pulses should be placed in a shielded box. The control circuit of the TEC temperature control or water-cooled pump should be stable, and its sensor signals should be properly filtered. The trigger switch signal line of the operating handle should be shielded and possibly optically isolated. The entire metal casing should be continuously grounded. For portable or home-use beauty devices, PCB layout and local shielding must be optimized within a compact space, ensuring compliance with emission standards for home environments.
