Study on Laser Frequency Short-Term Stability
Firstly, the short-term stability of the laser's frequency stabilized is theoretically studied by methods of third and fifth harmonic, and the experiment of increasing the frequency short-term stability is performed. Secondly, the semiconductor laser's frequency stabilized circuit system is discussed, and by useing this system to take the rubidium 87's hyperfine spectra F=2?kF'=3, 1 as reference frequency, that laser's frequency is stabilized by the third harmonic sign and fifth harmonic sign of saturated absorption spectra of 87Rb. The laser used is DL100 of TuiOptics, center wavelength is 780 nm, linewidth is 1 MHz, and finally a frequency stabilization got is 10-12. We computed the short-term stability generated by these two stablization technology theoretically is computed, and the calculated result with the experimental result is compared, and they were similar to each other.
