论文摘要
我们为适合加载离子陷阱的原子烤箱提供了设计,该设计是通过连续波多模二极管激光通过光学加热进行操作的。焦耳加热所需的低电阻电连接的缺失使烤箱可以从真空系统的其余部分进行热隔离,而对于含有钙的烤箱,我们实现了一个数量密度,适用于在激光损失限制的激光损失的〜200 mW的靶区域中的快速离子载荷。借助激光功率的简单进料,烤箱的转折时间小于20 s,而烤箱含有足够的钙,可以连续运行数千年,而无需补充。
We present a design for an atomic oven suitable for loading ion traps, which is operated via optical heating with a continuous-wave multimode diode laser. The absence of the low-resistance electrical connections necessary for Joule heating allows the oven to be extremely well thermally isolated from the rest of the vacuum system, and for an oven filled with calcium we achieve a number density suitable for rapid ion loading in the target region with ~200 mW of laser power, limited by radiative losses. With simple feedforward to the laser power, the turn-on time for the oven is less than 20 s, while the oven contains enough calcium to operate continuously for many thousands of years without replenishment.
