| Abstract(in English) | There is an idea to measure the time varying gravity field for the global observation of the environmental changes, using the laser interferometric technique for satellite-to-satellite tracking instead of using the radio technique as used in the current inter-satellite system, GRACE. It is required to measure the changes of the relative velocity between the twin satellites better than lOnm/s in averaging time for 1s ≦ τ ≦ 100s by using a frequency-stabilized laser light source which oscillates in frequency stability better than 10^<-12> in the square root of the Allan variance in this optical system. We are investigating availability of a diode laser as a light source of a laser interferometer in satellite by stabilizing its oscillation frequency using "double optical feedback" method to narrow its oscillation linewidth. |
