We describe a single beam compact spin exchange relaxation free (SERF) magnetometer whose configuration is simple and compatible with the silicon-glass bonding micro-machining method. Due to small size of vapor cell utilized in miniature atomic magnetometer, wall could not be neglected. In this study we show that Ne buffer gas more efficient than other typically species such as nitrogen helium for reduction theoretically experimentally. 3 Amagats (1 Amagat=2.69×1019/cm3) filled first...
Atomic magnetometers, a prominent class of quantum sensors, have become increasingly significant in magnetometry, with extensive applications cutting-edge physics, biomedical imaging, industrial inspection, and beyond. However, the power consumption an atomic magnetometer is primarily dominated by that demanded to heat vapor cell its operating temperature. This temperature determines alkali-metal density, thereby influencing magnetic field sensitivity overall consumption, which poses...

A Mach-Zehnder fiber optic sensor with high refractive index response sensitivity was developed. By fabricating a waist-enlarged bitaper structure on the interference arm of single mode-multimode-single mode (SMS) interferometer (MZI), spectral contrast and were improved. Subsequently, further improved by etching arm. When beam light introduced into sensor, due to structural mismatch between multimode normal transmission light, difference low-order high-order generated in core cladding. In...
