연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

Recently, lasers have become widely used throughout the medical treatment field. Several types of lasers have been used for the purpose of hair removal since the Alexandrite laser was approved by the FDA (Food & Drug Administration) for clinical epilation. In this study, a long-pulsed Alexandrite la...

제안 방법

  • In this study, we designed and fabricated the long-pulsed Alexandrite laser system adopting a multi-discharge method that can vary the pulse width in accordance with the consecutive turn-on of three flash lamps. And then using our laser system, we studied the hair removal characteristics on the back portion of the human hand and leg.
  • In this study, we designed and fabricated a long-pulsed Alexandrite 1 죠seT system adopting the multi-discharge method with the pulse width of 10ms to assist with our experiment on hair removal characteristics. At first, we accomplished the fundamental lasing experiment with the Alexandrite laser system and then experimented in earnest with the long-pulsed Alexandrite laser system adopting a multi-discharge method.
  • In this study, we designed and fabricated the long-pulsed Alexandrite laser system adopting a multi-discharge method that can vary the pulse width in accordance with the consecutive turn-on of three flash lamps. And then using our laser system, we studied the hair removal characteristics on the back portion of the human hand and leg.
  • In this study, we proposed a long-pulsed Alexandrite laser system adopting a multi-discharge method utilizing each SCR gate with an adjusting delay time by a PIC one- chip microprocessor. Using this system, we studied the hair removal characteristics.
