Abstract
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.

An Improved Method for Studying the Enzyme-Catalyzed Oxidation of Glucose Using Luminescent Probes
Matthew Cuber and J. N. Demas , William D. Bare and Chi V. PhamJournal of Chemical Education2007 84 (9), 1511An Improved Method for Studying the Enzyme-Catalyzed Oxidation of Glucose Using Luminescent Probes
Matthew Cuber and J. N. Demas , William D. Bare and Chi V. PhamJournal of Chemical Education2007 84 (9), 1511A new method is presented for measuring the rate of the oxidation of glucose in the presence of glucose oxidase. The improved method employs luminescence measurements to directly determine the concentration of oxygen in real time, thus obviating ...
