摘要：

Measurements of geometric parameters of a high-power infrared laser beam have been realized by three methods. The obtained results are in a satisfactory agreement with each other. When focusing the beam with wavelength of 1.064 mu m with a specially designed non-aberrational objective, a focal spot of approximately 40 mu m diameter could be obtained, with the waist length being 230-280 mu m. The measured parameters give an idea of the size of a laser plasma generated by this beam on a Xe gas microjet.
