The existing coherent light sources are nonuniformly distributed by frequency in the optical range. Thus, work toward the development of tunable lasers operating in the middle IR range has long been underway. Nevertheless, the region 4–8 µm has been poorly mastered, and more longwave lasers have too narrow frequency tuning ranges. One way of solving these problems is to harness the effect of parametric...
The absorption and fluorescence spectra of dimethyloxyluciferin (DMOL) and monomethyloxyluciferin (MMOL) were studied at pH 3.0–12.0 In the range of pH 3.0–8.0, the fluorescence spectrum of DMOL exhibits a maximum at λem = 639 nm. At higher pH values an additional emission maximum appears at λem = 500 nm (wavelength of excitation maximum λex = 350 nm), which intensity increases with time. It is shown...
