Abstract

From a CCRF-excited zinc vapour laser with overlapped DC-discharge were emitted following 6 laser lines: two blue at 491.162[nm] and 492.403[nm], an orange at 589.433[nm] and three infrared lines at 747.879[nm], 758.848[nm] and 773.25[nm]. The discharge parameters were determined for an optimal laser operation. At a RF-power of 400[W] with the frequency 13.56[MHz] the optimal temperature of the oven lay between 780[K] and 800[K], the He-pressure between 3.5[kPa] and 5.5[kPa].

직류방전이 추가로 인가된 용량결합고주파(CCRF)여기에 의한 아연증기레이저에서 6개의 레이저선들이 방출되었다. 이들의 파장은 491.162[nm]와 492.403[nm]의 청색선과 589.433[nm]의 오렌지선 그리고 747.979[nm], 758.848[nm], 773.25[nm]의 적외선 영역에 분포되어 있다. 최적의 레이저운전을 위해서 방전파라미터들이 결정되었다. 13.56[MHz]의 고주파전력 400[W]에서 오븐온도 $780{\sim}800[K]$, 헬륨압력 $3.5{\sim}5.5[kPa]$로 최적화되었다.
