Compact High-Finesse ULE Cavities for Laser Frequency Stabilization

Laser systems stabilized by reference cavities have many applications in science and modern technologies. In this research, a compact high-finesse cavity made of ULE (ultra low expansion) glass in a compact vacuum chamber is studied. Radiation stabilized by the cavity has a 50 Hz linewidth on the 50...

Description
Summary:Laser systems stabilized by reference cavities have many applications in science and modern technologies. In this research, a compact high-finesse cavity made of ULE (ultra low expansion) glass in a compact vacuum chamber is studied. Radiation stabilized by the cavity has a 50 Hz linewidth on the 50 ms averaging time and a fractional instability of 1.3 × 10 –13 on the15 ms averaging time. Cavities can be used to develop compact laser systems for transmitting highly stable signals via optical communication links, ranging, and in other applications.
