Glass neodymium

The opportunities for near-IR fluorescence sensors are of course not only limited to analytical chemistry. Physical parameters such as temperature can also be measured. For example, Grattan and Palmer have used the fluorescence lifetime quenching of neodymium glass fluorescence at 1054 nm, excited at 810 nm with a gallium-alumi-... 

To explain this application, we consider the schematic drawing of a giant pulse laser, shown in Fig. 7. Such a laser consists essentially of (1) a rod of active material AM (for example a ruby or neodymium glass or neodymium-doped rod of yttrium-aluminum garnet) excited by the light pulse from a flashlamp F,... 

For broader bandpass filters, neodymium glass filters are available for additional wavelength calibration in the visible region. Special NIST reference materials referred to as SRM (standard reference materials) numbers are available for calibration and verification from the National Institute of Standards and Technology. Information about these standards can be accessed directly from the Internet (http //www.i-nist. gov/itl/ div898 / index.html). 

Vollrath [132] and L Ast [102] reported the behavior of primary explosives with a pulsed-neodymium-glass (10,600 laser of 100 MW, emitting 30-nsee flashes. With a maximum energy of 3 J, diazodinitrophenol burned and potas-sium dinitrobenzofuroxan deflagrated or detonated. Lead and cadmium azides and lead styphnate gave consistent results ... 

The first LPy-GC experiments were conducted in the late 1960s and early 1970s on polymeric materials [85, 87—89]. The interaction of a laser beam with a substance is shown schematically in Fig. 3.7 [86]. A laser (e.g., ruby- or neodymium-glass) beam is focused and injected into the sample. The pulse duration is usually about 0.001 sec and the beam energy is about 5 J per pulse [85]. If this energy is focused on a spot... 

Near-i.r. irradiation has been used to photosensitize the production of singlet oxygen.2720 Dimol emission, 20a(1A ) -> 202(32 ) + hv633, has been observed from neodymium-glass-pumped oxygen in the gas phase and in 1,1,2-trichloro-trifluoroethane solution.2726...

With the discovery of the laser, it has been possible to irradiate materials with intense monochromatic light. Brish et al. [86] were the first to show that an intense infrared beam (X= 1060 nm) of light from a neodymium-glass laser could initiate lead azide. A point to be noted is that the wavelength of the light beam is far from the absorption edge of lead azide [2]. The Q-switched beam was 15 mm diam, was unfocused, and had a duration of 0.1 /isec. Lead azide of...
