| 内容記述 | We have developed a low-cost and simplified absolute wavelength standard for the cesium D1 line （894 nm） using a single-mode vertical-cavity surface-emitting laser （VCSEL） stabilized by a dichroic atomic vapor laser lock （DAVLL）. The DAVLL signal, obtained from the differential transmission of two orthogonal circular polarizations through cesium vapor in an external magnetic field, was optimized by adjusting the number and arrangement of ring-shaped permanent magnets. Using this optimized signal, a feedback control system was implemented to stabilize the VCSEL wavelength, resulting in a measured drift rate of 0.57 ± 0.01 kHz/s. These results suggest that using the stabilized VCSEL as a wavelength standard is effective for experiments that require determining the wavelength of another laser within a GHz-scale spectral region, with a precision better than 10 MHz for peak determination, despite the 50 MHz linewidth of the DAVLL signal, in situations where continuous scanning is not available. |
