The influence of probing gaussian beam focusing on photothermal signal was analyzed in the work. The probing beam parameters detection by quadrant photodiode was investigated. The photodiode current signal dependence on focal length of lens placed in the input of experimental setup for deferent probing beam parameters was studied.
