Influence Of Magnetic-Field Gradient On The Magneto-Optical Resonance Signal Linewidth With Anti-relaxation-coated Cells

In this work, we experimentally measure the broadened linewidth of magneto-optical resonance signal due to magnetic-field gradient with an alkali buffer-gas-free anti-relaxation-coated cell. We also study how the temperature of the atomic vapor cell affects the magneto-optical resonance signal linewidth under different magnetic-field gradients. Theoretical calculations show that the relaxation cau...
