Long-Term Frequency Stability Data

“Wavelength Scanning”: Wavelength data were acquired by varying the temperature of the laser crystal and monitoring the output with a wavelength meter.“Iodine Cell Absorption Peak”: The signal transmitted through the iodine cell was captured using a photodetector, yielding the corresponding dataset.“Power Monitoring”: The laser output power was measured with an optical power meter, resulting in the power data.“Frequency Stability Data”: The frequency corresponding to the iodine absorption peak was analyzed via a custom LabVIEW program, and the data were collected over an extended period to form the long-term frequency stability dataset.All data were processed using Origin software.
