Abstract

We present a dual isotope magneto-optical trap produced using a single diode laser. We generate all the optical frequencies needed for trapping both species using a fiber intensity modulator. All the optical frequencies are amplified simultaneously using a tapered amplifier. The independent control of each frequency is on the RF side rather than on the optical side. This introduces an enormous simplification for laser-cooling applications that often require an acousto-optic modulator for each laser beam. Frequency-changing capabilities are limited by the modulator bandwidth (10 GHz). Traps for more isotopes can be simply added by including additional RF frequencies on the modulator.

Fig. 1.
Fig. 1.

Experimental setup. In solid red lines are the optical paths and in dashed blue lines are the RF parts.

Fig. 2.
Fig. 2.

Spectrum of rubidium. The upper trace (dashed black line) shows the Doppler broadened spectrum of rubidium. The middle trace (solid black line) shows the excited-state hyperfine transitions with the zero frequency corresponding to the leftmost transition. The lower trace (solid red line) shows the spectrum of laser light out of the fiber modulator. The tallest peak is the carrier and the rest are sidebands. The three left sidebands are tuned to the required transitions for the DIMOT. The laser is locked at the carrier position. The energy levels for the two isotopes are shown on the right.

Fig. 3.
Fig. 3.

Fiber modulator characterization. It shows the first-order sideband amplitude (red squares), second-order sideband amplitude (green triangles), and visibility of the DC locking signal (blue diamonds). The solid lines correspond to the theoretical values. The fit is done to the first-order sideband to obtain the three curves as indicated in the text. The second-order sideband signal is buried in the noise for RF powers below 13 dBm.

Fig. 4.
Fig. 4.

Optical spectrum after the tapered amplifier measured in a Fabry–Perot cavity. The tallest peaks indicate the carrier and free spectral range of the cavity (1.5 GHz). The peaks with ν1=6589MHz and ν2=5458MHz correspond to the trapping frequencies, and the peak with ν3=2545MHz is the repumper frequency. The nonlinearities and blue detuned sidebands are also visible.

Fig. 5.

Atom number in the DIMOT. The sequence is Rb87 only—Rb87 and Rb85Rb87 only, with each stage lasting for 10 s; we turn the traps off at the end.
