Development of the Discharge Heated Copper Vapor Laser
방전가열형 구리증기레이저의 개발
Abstract
We have constructed and operated a discharge heated copper vapor laser which generated green (510.6 nm) and yellow (578.2 nm) light. The plasma tube was made of high purity (99.8%) alumina tube which has an inner diameter 25 mm and a length 106 cm. The electrodes, made of molybdenum sheet, were separated 108 cm apart. The laser gave an average power of 10 W at repetition rate of 5 kHz, charging voltage of 10 kV, Ne buffer gas pressure of 40 mbar, and the laser tube temperature of
방전가열형 구리증기레이저를 제작하였으며 그 동작특성을 조사하였다. 레이저관으로는 내경 25mm, 길이 106cm 인 고순도(99.8%) 알루미나관을 이용하였다. 방전전극은 molybdenum 튜브로 제작하였으며 전극간의 거리는 108cm 이었다. Ne 가스압력 40mbar, 충전전압 10kV, 반복률 5KHz, 레이저관 내부온도
