摘要：

A model for cw laser induced mode-mismatched dual-beam thermal lens spectrometry using probe beam profile detection has been developed. This model exhibits the following behavior: after passing through the thermal lens the TEM00 Gaussian probe beam becomes the superposition of several Gaussian beams of different parameters. This model has a compact mathematical expression, for which experimental proofs are given. © 1995 American Institute of Physics.
