Stabilization of Tunable Diode Lasers for Spectroscopy of Low Density Gases
スポンサーリンク
概要
- 論文の詳細を見る
A simple but efficient method for stabilizing tunable diode lasers (TDL) has been developed to improve the sensitivity of spectroscopy of low density gas. The same spectral line itself to be measured is broadened by pressure and is used as a frequency discriminator in the loop of stabilization. The frequency tuning range is wide enough to obtain a correct profile of the spectral line. A demonstrative observation has been done on the v_2asQ(7,6) transition of NH_3(929 cm^<-1>). With the TDL stabilization, the fluctuation of the TDL frequency is reduced to less than 1 MHz in several hours.
