我们描述了一种有效的外腔，用于缩小激光二极管阵列的多阵列堆叠的光谱线宽。对于商业上可获得的279 W自由运行的五阵列激光二极管阵列在60 A下工作，我们在115 W的连续功率输出下将光谱线宽在FWHM处缩窄至0.40 nm。该技术导致了更高效率、更低成本地生产用于磁共振成像的超极化惰性气体的可能性。
We describe an effective external cavity for narrowing the spectral linewidth of a multiarray stack of laser diode arrays. For a commercially available 279-W free-running five-array laser diode array operating at 60 A, we narrow the spectral linewidth to 0.40 nm at FWHM with 115 W of cw power output. This technique leads to the possibility of higher-efficiency, lower-cost production of hyperpolarized noble gases for magnetic resonance imaging.
