“…For example, in nuclear gamma-ray laser applications, nuclei with two excited states are needed, in which the lower state has a shorter lifetime, enabling a population inversion between them. Furthermore, in order to reduce the line-width difficulty [10,31], isomers with lifetime down to sub-nanoseconds are needed. it was thought to be impossible to produce such isomers with so short lifetimes with traditional accelerators or nuclear reactors [31].…”

Efficient production of metastable quantum states of nuclei (isomers) is critical for exotic applications, like nuclear clocks, nuclear batteries, clean nuclear energy, and nuclear gamma-ray lasers [1][2][3][4][5][6]. However, due to low reaction cross sections and quick decay, it is extremely difficult to acquire significant amount of isomers with short lifetimes via traditional accelerators or reactors. Here, we present femtosecond pumping of nuclear isomeric states by the Coulomb excitation of ions with the quivering electrons induced by laser fields for the first time. Nuclear isomers populated on the second excited state of 83 Kr, are generated with a rate of 3.84 × 10 17 per second from a table-top hundreds-TW laser system. This high efficiency of isomer production can be explained by Coulomb collision[7] of ions with the quivering electrons during the laser-cluster interactions at nearly solid densities.

“…On the other hand, narrow-band Xrays are used to investigate collective oscillations in solid density matter (Glenzer et al 2007;Glenzer and Redmer 2009;Neumayer et al 2010). There also exist theoretical suggestions for producing coherent light in the gammaray range, but which yet has to be realized in experiments (Baldwin and Solem 1997;Rivlin 2007;Rivlin and Zadernovsky 2010;Tkalya 2011;Son and Moon 2012). A functioning gamma-ray laser would have wideranging applications in experiments where matter could be investigated on sub-atomic scales.…”

We present a theoretical model for the generation of coherent gamma rays by a free electron laser, where a high-energy electron beam interacts with an electromagnetic wiggler. By replacing the static undulator with a 1-μm laser wiggler, the resulting radiation would go from X-rays currently observed in experiments, to gamma rays. Coherent light in the gamma-ray range would have wide-ranging applications in the probing of matter on sub-atomic scales

“…When the wavelength is comparable to or smaller than the Compton length, relativistic effects have to be taken into account, and leads to the Compton scattering, pair production and other effects in the interaction with matter [7]. Gamma ray lasers have been proposed theoretically [8][9][10][11][12] but has still to be realized in experiments. The production of coherent gamma radiation would open up the possibilities to explore matter on sub-atomic scales.…”

Resonant Compton scattering of electromagnetic waves in a quantum plasma

We consider the resonant scattering of coherent electromagnetic waves by a Raman-like process in the gamma ray range off electrostatic modes in a quantum plasma using a collective Klein-Gordon-Maxwell model. The growth rates for the most unstable modes are calculated theoretically, and the results are found to be more efficient than incoherent Compton scattering off individual electrons above a critical amplitude of the electromagnetic wave. The model does not predict Raman scattering off pair modes that exist in the Klein-Gordon-Maxwell model. The results are relevant for coherent gamma rays created in forthcoming laboratory experiments or in astrophysical objects.
