Coherent population trapping (CPT) is a common technique used in compact atomic clocks which requires two-phase coherent laser modes with a frequency difference in the GHz range for alkali atoms. To improve the performance vs size trade-off of Cs atomic clocks, we develop a laser source generating two cross-polarized coherent laser fields at 852 nm. It relies on the dual-frequency and dual-polarization operation of an optically-pumped vertical external-cavity semiconductor laser.
