Laser micro-spectroscopy experimental device consists of four parts laser, micro-optical systems, electronic control system, spectrograph or light meter. Figure (10-14) as shown by the laser (usually Q-switched solid-state lasers) issued by the laser beam is fired at the sample through the microscope objective, the sample evaporation in the region between the auxiliary electrode, the formation contains a certain number of electron, ion vapor cloud. Then, the electricity stored in the auxiliary electrode on the circuit capacitance through L, the R discharge in the vapor cloud, so that the atoms in the vapor cloud, the ion excitation and emission spectra. The use of microscopic optical system, lighting system to illuminate the sample. For opaque specimens, with a reflective optical path to illuminate the sample, the sample reflection illumination beam transflective mirror, steering prism into the eyepiece; adjust the position of the specimen through the eyepiece, and micro-alignment laser to be analyzed beam (ie, a microscope objective lens optical axis direction). Transparent sample, the transmission optical path to illuminate the sample from below. 18th century semi-Ye Faming photo Diban photography is actually done in the energy transfer and electron transfer in redox reactions. Laser chemical process is the most important response is to cut off the molecules (molecular bonds disconnected). As shown in Figure 10-10, evaporation prior to laser irradiation ABC combination of molecular, molecular bond cleavage to generate the AB and C, two fragments. These two parts were evaporated to the substrate, and then combine to form the film.Slow dissociation of speed, only the ns to μs, level. In order to overcome these difficulties, the concept of inertial confinement (inertial confinement fusion, ICF), the, this is the uniform irradiation of the use of high-power laser beam or particle beam fusion materials made of micro-pellet in a very short period of time rapidly heating the compressed fusion materials so as to reach a high temperature and density reach before its dispersion away from the fusion reaction conditions, causing the fusion reaction conditions.
Atoms and photons exchange momentum and the formation of an atom-photon entangled with each other entity, slow atoms in which no rules move and can not escape. Steven Chu this entity called "optical molasses, which is a way to trap atoms to make gathering.
