Paper Abstract

We report for first time, to our best knowledge, experimental measurement of the degree of spatial coherence of a λ532 nm laser source (of a DPSS type - frequency doubled Nd:YVO4 laser) by reversal shear interferometers developed in our laboratories not so long. The degree of a full-sized non-apertured laser beam turned out to be quite high viz. up to 0.6 which is comparable with the degree of spatial coherence of λ510 nm copper lasers we had measured repeatedly for last decade.
