Calculation Results

All the calculations of the characteristics of the alteration of cavity stability, S(t), described below were performed using data from experiments for He-Xe and Ar-Xe mixtures (the LUNA-2 M setup with planar uranium layers and the VIR-2 M reactor), as well as Ar-Xe and Kr-Xe mixtures (a cell with a cylindrical uranium layer and the TIBR-1 M reactor). The laser […]

Some Schemes for Nuclear Laser Devices Using Condensed Media

Thus, NPLs using condensed media have for the present given rather modest results: pumping has only been done on glass neodymium lasers with optical radiations from NOCs. Moreover, there is no detailed information on the charac­teristics of these lasers. Despite this, the literature has proposed some schemes for powerful nuclear-laser devices based on condensed laser media. We will review some […]

Lasers with Nuclear Pumping

The majority of the credit for this book on nuclear-pumped lasers (NPLs) goes to its original Russian authors. I (George H. Miley) became the contributing American co-author when I learned of the Russian version of the book and proposed to develop a version in English. After correspondence with the Russian authors, I obtained permission from them to work on the […]

Chemical Lasers

The interest in chemical lasers [173] may be explained by the fact that for them, in CW mode, high output powers of up to several megawatts have been obtained [174]. Various methods of acting on the active medium are used to initiate chemical lasers: gas discharge, photoinitiation, fast electron beams, у radiation from a nuclear explosion, etc.

Development of Laser Setups Based on Gas NPLs in the United States

In the United States, high-power NPL-based laser setups were developed in the scope of the FALCON program (Fission-Activated Laser CONcept) with Depart­ment of Energy support [37]. The basic executors of this program were the Sandia Laboratories with the support of the Idaho National Engineering Laboratory. Other participants included the Air Force Philips Laboratory, Los Alamos National Laboratory (LANL), Oak Ridge […]

Comments About NPL Research in the United States

A brief historic outline of NPL developments to date in the United States is given in Table 13.1. Clearly, parallel developments were achieved in Russia, and a history of these developments is discussed in previous chapters. Also, the history of early developments in the United States has been detailed in several review articles [1, 2, 10—13], so only the highlights […]

Laser Receivers

Under the influence of reactor n, y-radiation on the photoreceivers, additional radiation currents arise, integral and spectral sensitivities are altered, the level of intrinsic noise increases, and the shape of the volt-amp characteristic is changed [40]. The degree of influence of reactor radiation depends first of all on the type of receiver and the absorbed dose rate. Some results for […]
