New Developments in Laser Spectroscopy,istribution of blackbody radiation, the introduction of the concept of electron spin after the spectroscopic discovery of the fine structure in atomic spectra [14.3], or the test of quantum electrodynamics by precision measurements of the Lamb shift [14.4]. In this chapter some of these new and exciting developments are presented.

特征

Absorption and Emission of Light, modes in order to elucidate differences and connections between spontaneous and induced emission and absorption. This leads to the definition of the Einstein coefficients and their mutual relations. The next section explains some definitions used in photometry such as radiation power, intensity, and spectral power density.

Spectroscopic Instrumentation,ve for the success of an experimental investigation. Since the development of spectroscopic instrumentation has shown great progress in recent years, it is most important for any spectroscopist to be informed about the state-of-the-art regarding sensitivity, spectral resolving power, and signal-to-noise ratios attainable with modern equipment.
