我们描述了一个锁相激光系统的发展，适合于基于离子阱的量子信息处理器与（40）Ca（+）。分别具有约850和854 nm的输出激光波长的扩展腔二极管激光器和Ti：蓝宝石激光器的激光输出被相位锁定并用于激发D（3/2）和D（5/2）亚稳态量子位之间的拉曼跃迁。介绍了激光系统的研制和性能。我们还比较了所开发的量子位耦合与传统方法的特性和优点。
We describe the development of a phase-locked laser system tailored to an ion-trap-based quantum information processor with (40)Ca(+). Laser outputs from an extended cavity diode laser and a Ti:sapphire laser with output laser wavelengths of approximately 850 and 854 nm, respectively, were phase locked and used to excite a Raman transition between the D(3/2) and D(5/2) metastable states qubit. Development and the performance of the laser system are described. We also compare the characteristics and the benefits of the developed qubit coupling with those in the conventional approaches.
