摘要： A spectroscopy system may include a first laser and a second laser. The first laser is triggered to induce a plasma, such as on a surface of a target at a stand-off distance from the target. The second laser stimulates amplified emissions from the plasma that are detected by one or more spectroscopes. The gain induced by the second laser provides for detection of traces of explosives and other substances on surfaces at stand-off distances. For example, a carbon dioxide laser emits a laser beam at a wavelength of 10,600 nanometers that amplifies the detected signal of a YAG laser, such as Nd:YAG or Er: YAG. The YAG laser may be frequency-shifted to eye safe frequencies and may be focused using telescopic optics. The spectroscopy systemss may use the same telescopic optics to collect emissions from the detection surface and may be activated at or just before the peak emission intensity useful for detecting element signatures and intensity ratios from the trace elements in the plasma. Control of mobility, aiming, triggering, detection and focusing may provide a rapid fire, stand-off detection system for traces of explosives and other hazardous substances.

摘要： Probe beams are scanned with respect to waveguide substrates to generate optical harmonics. Detection of the optical harmonic radiation is used to image waveguide cores, claddings, or other structures such as electrodes. The detected optical radiation can also be used to provide estimates of linear electrooptic coefficients, or ratios of linear electrooptic coefficients. In some cases, the poling of polymer waveguide structures is monitored during fabrication based on a second harmonic of the probe beam. In some examples, third harmonic generation is used for imaging of conductive layers.

摘要： Sensors and/or taggants feature high optical gain materials which are disposed in a high scattering environment. These materials, when adequately excited, emit intense and spectrally narrow light that is dependent on the chemical environment in which high gain materials are dispersed. When two materials are placed in the same high scattering environment, the spectral emission properties of each emitter will depend on the chemical composition of the surrounding medium. The switching or transferring of energy from one emitter to the other when the chemical environment is changed in a specific manner is enabled and a shift in the spectral emissions can be detected and/or predicted.
