摘要:

我们展示了一种新型的紧凑型固体激光器源,用于氢原子$1S-2S$跃迁的高分辨率双光子光谱。该光源在243 nm处发射高达20 mW的光,由972 nm二极管激光器、锥形放大器和两个倍频级组成。二极管激光器被主动稳定到高精细度腔。我们比较了新的来源,在以前的实验中使用的稳定的486 nm染料激光器和记录1 S-2S光谱使用这两个系统。利用该固体激光器系统,我们证明了氢谱仪的分辨率为6 \times 10^{11},这对于类氢系统的一些高精度测量是有希望的。

英文摘要:

We demonstrate a novel compact solid-state laser source for high-resolution two-photon spectroscopy of the $1S-2S$ transition in atomic hydrogen. The source emits up to 20 mW at 243 nm and consists of a 972 nm diode laser, a tapered amplifier, and two doubling stages. The diode laser is actively stabilized to a high-finesse cavity. We compare the new source to the stable 486 nm dye laser used in previous experiments and record 1S-2S spectra using both systems. With the solid-state laser system we demonstrate a resolution of the hydrogen spectrometer of 6 \times 10^{11} which is promising for a number of high-precision measurements in hydrogen-like systems.
