A Voigt Laser Operating on Cs 852 nm Transition

We investigate a "Voigt laser" at Cs-D2 resonance line 852 nm using a Voigt anomalous dispersion optical filter (VADOF) as frequency-selecting element. The wavelength of the Voigt laser is stabilized within transmission frequency region of 852 nm VADOF, and the peak of the transmission is corresponding to Cs atomic Doppler broadened line. It works stably over a range of laser diode (LD) current from 60 to 140 mA. Moreover, the Voigt laser frequency could be selected by adjusting the cell temperature of the VADOF. With excellent frequency stability and immunity to the diode laser current and temperature, the Voigt laser could contribute to the development of the compact optical frequency standard, and can serve for the atomic clocks, atomic gravimeters, and atomic gyroscopes.
