Abstract
A new laser diode pain attenuater was developed. Light power out put was increased to 60mW (830nm) and resulted much more effective than the former type (15-20mW, 830nm).
Besides light weight and easy operati (6.5kg 440/350/150mm), the safety considerations were made such as skin tuch sencing switch, two kind of sound signals (pre-warning and waning), and red ligh signal (LED) for laser irradiation, etc.
A basic study to clearify the mechanism of laser effect is now underway.
