Infrared pulse
WebbMaterials with multiple nonlinear-optical responses have been investigated widely in recent years. Here, we report a hybrid system with both giant multiphoton absorption (MPA) and efficient third harmonic generation (THG) excited by near-infrared femtosecond laser pulses. The hybrid material consists of both WebbThe mandatory IrPHY ( Infrared Physical Layer Specification) is the physical layer of the IrDA specifications. It comprises optical link definitions, modulation, coding, cyclic redundancy check (CRC) and the framer. Different data rates use different modulation/coding schemes: SIR: 9.6–115.2 kbit/s, asynchronous, RZI, UART-like, 3/16 …

WebbRange-gated imaging permits imaging at long ranges while minimizing the effect of obscurants (fog, rain, or smoke) in the atmosphere. In range-gated imaging, a pulsed laser is used to illuminate the scene while the reflected light is detected by a camera with a short exposure time referred to as a gate. The gate is delayed so imaging occurs at ... WebbThe intensity of a rather weak laser pulse (<1 nJ/pulse) can induce the simultaneous three-photon absorption leading to the colorization, while much weaker intensity induces two-photon absorption resulting in the decolorization. The spatial patterning concomitant with higher-order multiphoton absorption processes was also demonstrated.
WebbThermographic inspection of material can be regarded as a method of infrared defectoscopy, that is capable of revealing material imperfections such as cracks, defects, voids, cavities and other inhomogeneities. The thermographic testing can be provided on individual components in a laboratory or directly on technology facilities that are in duty.
