直到最近，二极管激光器还只能在波长超过635 nm的地方使用，并且在化学实验中的用途有限，然而，技术突破使制造波长短至395 nm的蓝紫色二极管激光器成为可能。这些设备的商业化是由它们在数据存储方面的优势推动的，预计它们将在明年大规模生产并以低成本提供。本文介绍了三个证明蓝色二极管激光器在化学教育中的潜力的实验：光电效应测量、激光诱导荧光和光电流光谱分析。
Until recently diode lasers were only available at wavelengths longer than 635 nm and were of limited use for chemistry experiments, however technological breakthroughs have made possible the fabrication of blue and violet diode lasers that emit light at wavelengths as short as 395 nm. The commercialization of these devices is driven by their advantages for data storage, and they are expected to be mass produced and available at low cost within the next year. This paper presents three experiments that demonstrate the potential for blue diode lasers in chemical education: photoelectric effect measurements, laser-induced fluorescence, and optogalvanic spectroscopy.
