Abstract: The spatial coherence of the radiation emitted by a single-frequency ring Nd : YAG chip laser with a diode pumping was determined. The maximum value of the degrees coherence was 0.99994±0.00003. The factors limiting the spatial coherence of the radiation of low-power diode-pumped solid-state lasers was discussed.
