An 852 nm Faraday laser with 8 kHz linewidth based on corner-cube retroreflector
A single-mode Cs atom 852 nm Faraday laser based on the corner-cube reflector
feedback is first demonstrated to our best knowledge. Using the corner-cube
reflector as external cavity feedback in Faraday laser, the robustness can be
greatly improved. This Faraday laser can always achieve laser oscillation
unless the angle between incident light and the optical axis of corner-cube
retroreflector is beyond the plus or minus 3{\deg} range. Furthermore, the
Faraday laser achieves single-mode operation within the current range of 100 mA
, and its output wavelength is automatically limited to the vicinity of the Cs
atomic transition lines. The wavelength fluctuation range is limited to plus or
minus 1.2 pm within 9 hours under +3{\deg} rotation angle. Moreover, the most
probable linewidth is 7.97 kHz measured by heterodyne beating. The Faraday
laser with high robustness as well as narrow linewidth can be widely used in
quantum precision measurement fields including quantum optics, atomic clocks,
atomic magnetometers, cold atoms, and atomic gravimeters, etc
