Abstract
The method of measurement of thermo-optical distortions (a thermal lens) in the active element Nd:YVO4 arising under axial diode pumping which distinctive feature is simplicity of processing and speed of reception of results of measuring have been described. Investigations were realized by means of Hartmann method based on monitoring of parameters of pumping radiation wave-front passing through investigated optical element. It is shown, that the proposed method enables direct investigation of thermo-optical distortions in small pumped areas (hundreds and tens micrometers). Presented is a method for research of thermo-optical distortions in an active element ensuring direct measurement of high orders aberrations.
