optical telecommunications components and frequency doubling to generate light at 780 nm. Using a fast, fibrecoupled
intensity modulator, output from a continuous laser diode is sliced into pulses with a length between
1.3 and 6.1 ns and a repetition frequency of 5 MHz. These pulses are amplified using an erbium-doped fibre
amplifier, and frequency-doubled in a periodically poled lithium niobate crystal, yielding a peak power up to
12 W. Using the resulting light at 780 nm, we demonstrate Rabi oscillations on the F = 2↔F′ = 3-transition
of a single 87Rb atom.详细>
