This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers.

A book with such an interdisciplinary scope has not been available to date. Astrophysical Lasers Vladilen Letokhov and Sveneric Johansson. First book on this subject; Unique combination of laser physics, astrophysics and atomic physics; New field of research for planning very large optical telescope; Accessible.

The book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers.

The book will also be useful for a wider audience interested in. Both maser and laser effects, first demonstrated under laboratory conditions, have now been discovered to occur under natural conditions in space too.

This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical : Vladilen Letokhov.

This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers. A book with such an interdisciplinary scope has not been available to date.

Unlike terrestrial lasers and masers for which the excitation mechanism is known and engineered, the reverse is true for astrophysical masers. In general, astrophysical masers are discovered empirically then studied further in order to develop plausible suggestions about possible pumping schemes.

This chapter describes an astrophysical laser in the line Å O I. Topics covered include spectral anomalies in O I in stars, excitation mechanisms of O I in the Weigelt blots, inverted population and amplification coefficient of the Å line, spatial features of the O I laser in the Weigelt blobs, and possible O I lasers in stellar atmospheres and Orion Nebulae.

Astrophysical lasers emitting in the optical range, which are discussed in this paper, were discovered quite recently, 40 years after the creation of the laboratory laser. However, their roots can be traced back as early as in the s–s, i.e.

Interest in naturally occurring lasers has dwindled. Strelnitski still works with students to further study MWCA, but he no longer researches astrophysical lasers as actively as before. Mumma, who still works at NASA, changed his research focus years ago.

Johansson passed away inand Letokhov just months later, in Laser experiments to study an astrophysical object typically try to preserve dimensionless numbers that are characteristic of the important physics (e.g.\ Mach number).

Euler scaling [14] is used for the hydrodynamics where sizes, densities, pressures and timescales are scaled like in a wind-tunnel trial. This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers.

Intense lasers are now being used to recreate aspects of astrophysical phenomena in the laboratory, allowing the creation of experimental testbeds where theory and modeling can be quantitatively tested against data.

We describe here several areas of astrophysics—supernovae, supernova remnants, gamma-ray bursts, and giant planets—where laser.

Buy Astrophysical Masers (IAU S): Unlocking the Mysteries of the Universe Masers are the microwave analogue of lasers; there are many astronomical sources of natural maser emission, including gas around forming and dying stars, and around supermassive black holes.

These bright sources of microwaves are fascinating in their own right and. However, the laser impact has unwanted side effects: It generates a strong electromagnetic pulse and a gammy-ray flash that interfere with the sensitive measuring instruments used for this detection.

This chapter presents an overview of ideas of the nonequilibrium state of matter that emerged in the last thirty years of the 20th century, which are surprisingly similar to the schemes for laser pumping.

Topics discussed include amplification under non-low thermal equilibrium (LTE) conditions, astrophysical predecessors of the laser, and manifestation of laser action under astrophysical.
