Optical Engineering400 Hz frequency stability of a GaAlAs laser frequency locked to the Rb (D2) line
|Format||Member Price||Non-Member Price|
A commercial GaAlAs injection laser is frequency locked to the Rb (D2) transition. A relative frequency stability of 400 Hz is measured for a 24-s averaging time. The frequency stability of this device with only temperature control is 4 kHz. This is a factor of 20 improvement in the state of the art for temperature control stability for semiconductor lasers.
