We report the development of laser systems -- a "Voigt laser" -- using aVoigt anomalous dispersion optical filter as the frequency-selective element,working at the wavelength of 780 nm of $^{87}$Rb-D2 resonance line. Comparedwith Faraday anomalous dispersion optical filter, the Voigt anomalousdispersion optical filter can generate a stronger and more uniform magneticfield with a compact size of magnet, and obtains a transmission spectrum withnarrower linewidth and more stable lineprofile. In this case, the frequencystability of the Voigt laser reaches 5$\times$10$^{-9}$ at the averaging timeof 200 s, and the wavelength fluctuation of 8-hours free operation is $\pm$0.1pm. Besides, the Voigt laser has greater immunity to diode current than theFaraday laser, with a wavelength fluctuation of $\pm$0.5 pm in the currentrange from 73 mA to 150 mA. Finally, the Voigt laser frequency can becontrolled by the cell temperature of the Voigt optical filter, which isexpected to achieve a frequency detuning of 20 GHz. Consequently, the Voigtlaser, whose frequency could correspond to the atomic transition frequency bytuning the cell temperature, obtains good robustness to the current andtemperature fluctuation of laser diode, and could realize a compact opticalstandard for precise measurement once stabilized by modulation transferspectroscopy.
