| Abstract(in English) | We expect that semiconductor lasers are useful for precise interferometric systems employed in artificial satellites, by virtue of their overall compactness, lightweight, durability and energy-efficiency. However, stability of their oscillation frequency and broad-spectrum linewidth are obstacles in this area. Once we find a way to sidestep that issue by stabilization, satellite-to-satellite tracking laser interferometers will measure fluctuations in earth's gravitational field with a level of precision we can now only dream of. Thus far, we have succeeded in stabilizing semiconductor lasers' frequencies to Rb-saturated absorption lines. In order to narrow oscillation linewidth, we introduced "Double Optical Feedback". This double optical feedback system reduces oscillation linewidth and also reduces fluctuations in intensity and frequency, without resorting to mechanical control elements. |
