Laser frequency offset locking by marrying modulation sideband with the two-color polarization spectroscopy in a ladder-type atomic system
نویسندگان
چکیده
We present an investigation of two-color polarization spectroscopy (TCPS) based on cesium 6S1/2–6P3/2– 7S1/2 (852 nmþ1470 nm) ladder-type system in a room-temperature vapor cell. The 1470 nm laser can be offset locked by TCPS combining with frequency modulation sideband. This locking scheme offers a method of modulation-free and conveniently tunable the lock point of laser frequency relative to an excited state transition, and may have many applications such as in two-color magneto-optical trap, diamond-level structure four-wave mixing experiments. & 2014 Published by Elsevier B.V.

Sub-kilohertz laser linewidth narrowing using polarization spectroscopy.
We identify several beneficial characteristics of polarization spectroscopy as an absolute atomic reference for frequency stabilization of lasers, and demonstrate sub-kilohertz laser spectral linewidth narrowing using polarization spectroscopy with high-bandwidth feedback. Polarization spectroscopy provides a highly dispersive velocity-selective absolute atomic reference based on frequency-depe...
متن کاملDemonstration of injection locking a diode laser using a ®ltered electro-optic modulator sideband
Many experiments in atomic physics require two laser beams with a controllable dierence in frequencies. In this paper, we report on realizing this goal using a technique where an electro-optic modulator sideband is ®ltered through a cavity and injected into a diode laser, in a novel con®guration yielding very high feedback isolation without sacri®cing access to the output power of the diode la...

A novel optical millimeter-wave generation using sideband injection locking is demonstrated using monolithic two-section DFB lasers. The tunable millimeter-wave is generated by adjusting the RF-modulation frequency and bias currents. Summary The optical generation of millimeter-wave has been demonstrated and attracted much attention because of its flexibility and applicability in broadband mobi...
متن کاملOptical single sideband polarization modulation for radio-over-fiber system and microwave photonic signal processing
An approach to implementing optical single sideband (OSSB) polarization modulation, which is a combination of two orthogonally polarized OSSB modulations with complementary phase differences between the optical carrier and the sideband, is demonstrated based on two cascaded polarization modulators (PolMs). The two PolMs are driven by two RF signals that are 90° out of phase. By properly adjusti...
متن کاملAlternative laser system for cesium magneto-optical trap via optical injection locking to sideband of a 9-GHz current-modulated diode laser.
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...
