Frequency stabilization of HeNe laser for interferometry
간섭계용 헬륨-네온 레이저의 주파수 안정화
Abstract
Lasers are used as the source of the interferometers in the industrial field. These lasers need 2 requirements. The first is the narrow linewidth of laser for the long coherence length. The second is the stabilized frequency of laser for the precision measurement. Now HeNe lasers are mostly used and the frequency stability is about 10
