Abstract
This paper presents results of experimental studies of the spatial profile of the beam in lasers with an antiresonant ring. The near-field profile of the beam was measured by the pin-hole technique. In case of the active crystal placed into the ring, the beam profile was found to be Gaussian within a wide range of the pumping power. Variation of the width of the Gaussian profile is caused by the thermal lens in the active crystal. Measurements of the FWHM of the Gaussian profile demonstrated that it is proportional to the one-fourth power of the focal length of the thermal lens, as in the case of a stable cavity.
