The present invention relates to an apparatus for stabilizing second harmonic wave pulse output in a laser system operating by pulses. The apparatus of the present invention comprises: a pulse laser oscillating unit (110) which outputs a laser pulse; a nonlinear crystal (120) which converts the laser pulse of a first wavelength output by the pulse laser oscillation unit (110) into a second harmonic wave with a value that is half of the first wavelength, and outputs the converted second harmonic wave; and an optical absorption filter (130) which absorbs a portion of the energy of the converted second harmonic laser pulse from the nonlinear crystal (120) to output the second harmonic wave with a lower energy. The thus-configured apparatus of the present invention supplies a fundamental wave in a stable state and having a small PTP value and high level energy to the nonlinear crystal, in order to obtain the second harmonic wave which is in a more stable state and has a small PTP value and a variety of energies.

The present disclosure relates to an EMS method using EMS electrode pads. Each electrode may be provided to correspond to the shape and size of the divided area according to the virtual line. The EMS method using the same according to the present invention may minimize the edge current effect by the shape of the electrode to which electric energy is applied. In addition, energy transfer efficiency may be improved by capacitive coupling between the electrode and the skin. In addition, due to the coating of the electrode, a rate of contact with an affected part may be increased so that current may be applied evenly to each part.
