Laser Absorption Spectroscopy: Comparison
Please note this is a comparison between Version 1 by JINYI LI and Version 2 by Rita Xu.

Laser absorption spectroscopy (LAS) is an absorption spectroscopic method that employs a laser as the light source and measures the chemical concentration based on detection of a variation of laser beam intensity after transmission along the optical path.
