Ya. B. Zeldovich All-Moscow Seminar of Astrophysicists

In favor of  the 100 year anniversary of the Einstein GR theory 

a brief review of modern laser and optical technique in application 

of fundamental problems of Gravitation and General Relativity is presented. 

In that number there are the Redshift measurement with optical standards, 

Earth gravity acceleration and Gravitational coupling constant measurement 

with fountain gravimeters and atomic interferometers, direct observation of 

cosmological expansion with laser frequency comb spectroscopy, 

gravitational wave detection with the long based laser interferometers etc.
