摘要：
We report on a new coherent source that, using a phase-lock scheme to an optical frequency-comb synthesizer, achieves a 10-Hz intrinsic linewidth, is tunable from 4 to 4.5 mu m with a presettable absolute frequency and, when coupled to a high-finesse cavity, can provide a short-term absorption sensitivity of 1.3 . 10(-11) cm(-1)Hz(-1/2). These unique spectral features make this source a precise tool for molecular physics. (C) 2009 Optical Society of America
