"Double-beam Thermal Lens Spectrometry"
Anal. Chem. 1985 Volume 57, Issue 13 Pages 2434-2436

Abstract: The construction of a double-beam configuration for thermal-lens absorption measurements is reported, in which a single laser beam is split into two, only one beam being passed through the sample. Continuous modulation and lock-in amplification of the signal produced by subtraction of the beam intensities allow application of the system to real-time monitoring, such as flow injection analysis or HPLC. Double-beam thermal-lens detection was evaluated for the flow injection analysis of trace levels of iodine in CCl4.
