Available in PDF, EPUB and Kindle. Book excerpt: The aim of the research program was the long-term stabilization of the frequency of the 5145 A argon ion laser by using an I2 resonance, observed in a molecular beam, as a reference. The major accomplishments and the status of the program are outlined below. The 5145 A argon ion laser has been locked to a hyperfine transition in a molecular beam of I2. Two methods were used to measure the long-term frequency drift. The first method is the simpler one, and only requires one additional molecular beam apparatus. Here, the laser frequency drift is monitored by measuring the shift of the laser frequency with respect to the center of the same I2 transition observed in an independent molecular beam. In the second and more conventional method, two argon lasers are independently stabilized to adjacent I2 transitions in independent molecular beams. The two laser outputs are mixed on a fast photodiode, and the resulting beat frequency gives an accurate measure of frequency stability. Both methods yielded similar results; i.e., better than one-part-in 10 to the 13th power in an integration time of about 100 seconds. This was the highest stability achieved in the visible region of the spectrum at the time the measurements were made. The shift in the stabilized laser frequency as a function of laser intensity was found to be less than two-parts-in 10 to the 14th power for a 1% change in laser intensity at I mW. This value is still an upper limit at present, pending a more detailed study.

Available in PDF, EPUB and Kindle. Book excerpt: The impact of lasers on spectroscopy can hardly be overestimated. Lasers re present intense light sources with spectral energy densities which may exceed those of i ncoheren t sources by severa 1 orders of magnitude. Furthermore be cause of their extremely small bandwidth, single-mode lasers allow a spectral resolution which far exceeds that of conventional spectrometers. Many experi ments which could not be done before the application of lasers because of lack of intensity or insufficient resol ution are readily performed wi th lasers. Now several thousands of laser lines are known which span the whole spec tral range from the vacuum-ultraviolet to the far-infrared region. Of parti cular interest are the continuously tunable lasers which may in many cases replace wavelength-selecting elements, such as spectrometers or interferome ters. In combination with optical frequency mixing, techniques such conti nuously tunable monochromatic coherent light sources are available at nearly any desired wavelength above 100 nm.

This book was released on 2014-05-08 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum Electronics for Atomic Physics provides a course in quantum electronics for researchers in atomic physics and other related areas such as telecommunications. The book covers the usual topics, such as Gaussian beams, lasers, nonlinear optics and modulation techniques, but also includes a number of areas not usually found in a textbook on quantum electronics. Among the latter are such practical matters as the enhancement of nonlinear processes in a build-up cavity or periodically polled waveguide, impedance matching into a cavity, laser frequency stabilization (including servomechanism theory), astigmatism in ring cavities, and frequency locking a laser to an atomic or molecular line. The second edition includes a new complete chapter on optical waveguide theory, fiber optic components and fiber lasers. Other updates include new coverage of mode locked fiber lasers, comb generation in a micro-resonator, and periodically poled optical waveguides.
