Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). Laser cooling and laser trapping include a number of techniques in which atomic and molecular samples are cooled down to near absolute zero.Laser cooling techniques rely on the fact that when an object (usually an atom) absorbs and re-emits a photon (a particle of light) its momentum changes. From threading to grinding to high-precision swiss-type turning, FANUC technologies provide the features and functionality to make running your production process easier and more profitable. Pulsed lasers are more frequently used since they can add time Resonance occurs when a system is able to store and easily transfer energy between two or more different storage modes (such as kinetic energy and potential energy in the case of a simple pendulum). The effect of a capacitor is known as capacitance.While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.The capacitor was originally known as a lasers, and discusses the role of optical resonators and techniques for realizing tunable narrowband lasers, the working horses of laser spectroscopy. A model for coupled radiation transfer and thermal diffusion is proposed, which provides a local temperature field. Certain types of microwave, optical, and gamma-ray spectroscopy are capable of measuring infinitesimal frequency shifts in narrow spectroscopic lines.
