FIG. 1.

Schematic of ARLD external-cavity laser. Laser transmits through FADOF, is fed backed by a highly reflecting mirror, and outputs at the half-reflecting mirror. The reflectance of highly reflecting mirror is .

FIG. 2.

Fluorescence spectrum of ARLD without external feedback (the temperature and current of the ARLD are 21.24 °C and 78.93 mA).

(a) is the transmission spectrum of Rb FADOF and the fluorescence spectrum of Rb cell (the temperature and magnetic field of FADOF is 70 °C and  3.2 × 10−2 T. In the Rb cell, T = 24 °C and B = 0 T) and external-cavity longitudinal modes with interval of 379.7 MHz. The FWHM of the highest peak of Rb FADOF transmission spectrum is 1.3 GHz. (b) is temperature-wavelength curve, while current is kept at 74.04 mA. (c) is current-wavelength curves, while temperature is kept at 21.31 °C. Comparing (a) with (b) and (c) transversely, it shows that the wavelength of laser is well kept within the highest transmission peak.

FIG. 4.

Mode of the laser as measured by a Fabry-Perot interferometer. The free spectral range of the Fabry-Perot interferometer is 20 GHz.

Image of FIG. 5.
FIG. 5.

Beat signal between two identical ARLD external-cavity lasers together with its Gaussian and Lorentzian fits. The measurement duration of spectrum analyzer is 50 ms, the resolution bandwidth is 30 kHz, and the video bandwidth is 3 kHz. The FWHM of Gaussian fits is 97 kHz and that of Lorentzian fits is 90 kHz.
