摘　　要：The laser-induced thermal lens effect first discovered in 1964 by Gordon et al..is due to a refractive index gradient within a liquid sample upon irradiation with a Gaussian (TEM₀₀) laser beam. A liquid sample is placed in the beam of the laser. The liquid is heated by the absorbed power, a 'liquid lens' element formed causes the beam to di-
