论文摘要
我们在326.2〜nm处提出了一个新颖的高功率，频率稳定的UV激光源，与CD $^{1} $ S $ _ {0} $ - $^{3} $ p $ _ {1} $ narrow narrow narrow对间的过渡。我们在326.2〜nm处获得了1〜W的最大功率，通过两个连续的频率加倍阶段的狭窄线宽（<1〜kHz）种子激光器在1304.8〜nm处。可见的拉曼纤维放大器（VRFA）产生了约3.4 W的光功率，该光功能会放大并生成红外辐射的第二个谐波。 The visible light is subsequently frequency-doubled down to 326.2~nm in a non-linear bow-tie cavity using a Brewster-cut beta-barium-borate (BBO) crystal, with a maximum conversion efficiency of around 40$\%$ for 2.5~W coupled red power.显示了激光源的完整表征，以及所有CD同位素的光谱信号，跨越了UV中超过4 GHz。
We present a novel high-power, frequency-stabilized UV laser source at 326.2~nm, resonant with the Cd $^{1}$S$_{0}$ - $^{3}$P$_{1}$ narrow intercombination transition. We have achieved a maximum produced power of 1~W at 326.2~nm by two successive frequency doubling stages of a narrow-linewidth (< 1~kHz) seed laser at 1304.8~nm. About 3.4 W of optical power at 652.4 nm is produced by a visible Raman fiber amplifier (VRFA) that amplifies and generates the second harmonic of the infrared radiation. The visible light is subsequently frequency-doubled down to 326.2~nm in a non-linear bow-tie cavity using a Brewster-cut beta-barium-borate (BBO) crystal, with a maximum conversion efficiency of around 40$\%$ for 2.5~W coupled red power. Full characterization of the laser source, together with spectroscopy signals of all Cd isotopes, spanning more than 4 GHz in the UV, are shown.
