Abstract

We report on the frequency stabilization of an extended cavity diode laser for the coherent driving of thulium ions. This stabilization loop uses a single locking point on an intra-cavity electro-optic crystal. Thanks to this, the laser coherence time is much longer than the coherence lifetime of the thulium ions. The performances of this stabilized source are used in basic coherent driving experiments in a Tm3+:YAG crystal, highlighting the strong stability requirements of coherent processes.

In order to prepare rare earth ion pairs in an entangled state, we investigate coherent driving techniques with the help of a highly stabilized semiconductor laser. The ions are dispersed in a crystal at low temperature.

Rare earth ions in solids offer optical linewidths rivaling those of trapped single atoms. We design and characterize rare-earth-doped crystals for applications requiring long optical decoherence times (4.2 ms) and ultranarrow spectral holes (75 Hz).

Hybrid optical and electronic laser locking using slow light due to spectral holes

Jian Wei Tay, Warrick G. Farr, Patrick M. Ledingham +2 more

We report on a narrow linewidth laser diode system that is stabilized using both optical and electronic feedback to a spectral hole in cryogenic Tm:YAG. The large group delay of the spectral hole leads to a laser with very low phase noise. The laser has proved useful for quantum optics and sensing applications involving cryogenic rare-earth-ion dopants.

Laser Stabilisation Using a Slow Light Cavity

Teodor Strömberg

In this thesis the application of slow light effects to the area of laser stabilisation is investigated. The frequency stability of lasers locked to external cavities is limited by the stability of the modes in the reference cavity. By using dispersive slow light effects the effective length of a cavity can be increased by several orders of magnitude, without a proportional increase in the sensitivity to fluctuations in cavity length, thereby yielding a net increase in stability. The effects are achieved through spectral hole burning in cryogenically cooled rare-earth ion doped crystals. Two sets of experiments are carried out, the first focusing on hole burning and the second focusing laser locking. Linewidths and frequency drift of the cavity spectrum are studied. Feedback control using an error signal generated from the slow light cavity is demonstrated, but successfully locking the laser is still yet to be achieved.

Coherent Emission from Rare Earth Ions in Electro-optic Crystals

L. F. Johnson, A. A. Ballman

We report the observation of coherent emission from three rare-earth ions in electro-optic crystals. Oscillation is observed from Nd3+ ions in Bi4Ge3O12, LiNbO3, and Ba0.75Ca0.25Nb26O at room temperature, and from Tm3+ and Ho3+ ions in LiNbO3 at 77°K. Second-harmonic radiation is obtained from LiNbO3:Tm3+ and electric-field modulation of threshold is observed for certain crystals of LiNbO3:Nd3+. The latter effect is believed to arise from crystal strain. The propagation angle for phase-matched second-harmonic generation is calculated to lie at 43° to the c axis for both LiNbO3:Tm3+ and LiNbO3:Ho3+ at 77°K. Phasematched second-harmonic generation from LiNbO3:Nd3+ is not possible, since the maser line is an extraordinary wave. However, the polarization of the maser line in LiNbO3:Nd3+ is appropriate for phasematched parametric frequency conversion in the near infrared. Attempts to observe such radiation were not successful due to the limited power available in the fundamental.
