Laser spectroscopy system |
摘要 |
In order to provide a laser spectroscopy system of simple construction and free of the effect of the fringe noise and to provide a laser spectroscopy system in which a reference cell is efficiently installed with minimum cost and space, there is disclosed a laser spectroscopy system comprising: a tunable laser diode source for generating a laser beam used for spectroscopic analysis; a sample cell where a sample gas is introduced; a first photo detector for measuring an intensity of a laser beam transmitted through the sample cell and having a beam receiving face; a beam splitter for splitting a portion of the laser beam from the laser source; and a second photo detector for measuring an intensity of a splitted laser beam from the beam splitter and having a beam receiving face, wherein the at least one of beam receiving faces is tilted to be at a predetermined angle from an axis of laser beam.
