We have been developing high-power electrical supply units for high-power gas and solid lasers for
many years. Recently, we have also been developing a high performance power supply unit for
semiconductor lasers. We have also developed a medical therapy device for pain relaxation and
commercialized it using such experienced technologies of semiconductor laser power supply. We
describe the development and approval processes of the medical therapy device and disclose the effect of
a semiconductor laser device on pain relaxation.
