Injection locking of a trapped-ion phonon laser.

چکیده
We report on injection locking of optically excited mechanical oscillations of a single, trapped ion. The injection locking dynamics are studied by analyzing the oscillator spectrum with a spatially selective Fourier transform technique and the oscillator phase with stroboscopic imaging. In both cases we find excellent agreement with theory inside and outside the locking range. We attain injection locking with forces as low as 5(1)×10{-24} N so this system appears promising for the detection of ultraweak oscillating forces.

A trapped-ion phonon laser and the detection of ultra-weak forces
This dissertation reports on the demonstration of a mechanical analogue to an optical laser, a ”phonon laser”, using a single trapped ion. Furthermore, we show that the dynamics of this system are surprisingly sensitive to external fields; we demonstrate phase synchronization (”injection locking”) to an external signal by applying forces as weak as 5 yN (yocto=10). This enormous sensitivity mig...
متن کاملTrapped ion quantum computation with transverse phonon modes.
We propose a scheme to implement quantum gates on any pair of trapped ions immersed in a large linear crystal, using interaction mediated by the transverse phonon modes. Compared with the conventional approaches based on the longitudinal phonon modes, this scheme is much less sensitive to ion heating and thermal motion outside of the Lamb-Dicke limit thanks to the stronger confinement in the tr...
متن کاملThe 199 Hg + single ion optical clock : recent progress
We report on work directed toward the systematic evaluation of an optical frequency standard based on the S1/2–D5/2 transition of a single, laser-cooled, trapped 199Hg+ ion, whose resonance frequency is 1.06 × 1015 Hz. For the purpose of the evaluation, two 199Hg+ standards have been constructed. In the cooling-laser system built for the second standard, an injection-locking scheme has been app...

We report on work directed toward the systematic evaluation of an optical frequency standard based on the 2 1 25 2 transition of a single, laser-cooled, trapped Hg + ion, whose resonance frequency is 1.06 10Hz. For the purpose of the evaluation, a second 199Hg standard has been constructed. In the cooling-laser system built for the second standard, an injection-locking scheme has been applied t...
متن کاملTailoring of optical phonon modes in nanoscale semiconductor structures: role of interface-optical phonons in quantum-well lasers
This paper discusses the concept of enhancing semiconductor laser performance through tailoring of scattering rates of confined polar-optical phonons. Studies of optically pumped intersubband scattering in coupled quantum-well lasers have demonstrated that interface-phonon-assisted transitions are important in such structures; furthermore, simple analytical expressions have been derived that in...
