Probe beam image detection for mode-mismatched dual beam thermal lens spectrometry
Overview & Synopsis
A model for CW induced mode-mismatched dual-beam thermal lens spectrometry using the whole probe beam profile has been developed. This model quantitatively describes the intensity distribution before and after the thermal lens has been created. It is considered that after passing through the thermal lens, the TM00 Gaussian probe beam becomes the superposition of several Gaussian beams of different parameters. A compact mathematical expression was obtained, which allows absolute measurements of opthothermal properties of transparent samples. Experimental proofs have been displayed.
