We demonstrate the generation of two high-power laser beams whose frequencies are separated by the ground state hyperfine transition frequency in (87)Rb. The system uses a single master diode laser appropriately shifted by high frequency acousto-optic modulators and amplified by semiconductor tapered amplifiers. This produces two 1 W laser beams with a frequency spacing of 6.834 GHz and a relative frequency stability of 1 Hz. We discuss possible applications of this apparatus, including electromagnetically induced transparency-like effects and ultrafast qubit rotations.
我们展示了产生两束高功率激光束,其频率由(87)Rb中的基态超精细跃迁频率分开。该系统使用单个主二极管激光器,通过高频声光调制器进行适当频率偏移,并由半导体锥形放大器进行放大。这产生了两束功率为1 W的激光束,频率间隔为6.834 GHz,相对频率稳定性为1 Hz。我们讨论了该装置的可能应用,包括类电磁诱导透明效应和超快量子比特旋转。
