Abstract

By optical injection of an 852-nm extended-cavity diode laser (master laser) to lock the + 1-order sideband of a ~9-GHz-current-modulated diode laser (slave laser), we generate a pair of phase-locked lasers with a frequency difference up to ~9-GHz for a cesium (Cs) magneto-optical trap (MOT) with convenient tuning capability. For a cesium MOT, the master laser acts as repumping laser, locked to the Cs 6S1/2 (F = 3) - 6P3/2 (F’ = 4) transition. When the + 1-order sideband of the 8.9536-GHz-current-modulated slave laser is optically injection-locked, the carrier operates on the Cs 6S1/2 (F = 4) - 6P3/2 (F’ = 5) cooling cycle transition with −12 MHz detuning and acts as cooling/trapping laser. When carrying a 9.1926-GHz modulation signal, this phase-locked laser system can be applied in the fields of coherent population trapping and coherent manipulation of Cs atomic ground states.

Influence of the power of the RF modulation signal on the proportion of the + 1 sideband and the injection locking range of the slave laser when the + 1-order sideband is injection locked. The proportion of + 1 sideband (red circles) and the injection locking range (blue squares) are increased with the RF power.

SAS signals for both the master and slave lasers. The slave laser is directly modulated at 8.953613177 GHz. When the master laser used for the repumping laser of Cs MOT is scanned to the Cs F = 3 - F’ = 4 transition, the carrier of the slave laser with the + 1-order sideband injection locked used for the cooling/trapping laser of Cs MOT now is detuned by −12 MHz relative to the Cs F = 4 - F’ = 5 cooling cycle transition.
