“…It has been proposed [13] to amplify the undulator radiation at a wavelength of 12 ± 1 μm by means of optical parametric amplification in nonlinear crystals and to use obtained radiation for cooling particles in the relativistic beam. Nanosecond pulses of CO laser radiation were required for optical pumping of the nonlinear crystals.…”

The solution of problems related, e.g., to transport of laser radiation in the atmosphere requires availability of a broadband IR laser source operating in the transparency windows of the atmosphere. In this review, we present the results of an investigation of the properties of a hybrid laser system consisting of molecular gas pump lasers and a solid-state laser frequency converter based on nonlinear crystals. We demonstrate broadening and enrichment of spectrum of radiation of the pump laser by means of sum-and difference-frequency generation. In particular, by using a relatively simple laser system consisting of gas-discharge CO and CO 2 lasers, radiation tunable over a large number of spectral lines in a broad range of wavelength from 2.5 to 16.6 μm (more than two and a half octaves), which includes two transparency windows of the atmosphere, is obtained. Thus, the possibility of exploring the IR spectral range by means of hybrid laser systems based on frequency conversion of radiation of molecular gas lasers is demonstrated.

“…Recently a new method of EOC was suggested [4][5][6][7] and in this proposal we discuss an experiment which might test this method in an existing electron storage ring having maximal energy ~ 2.5 GeV, and which can also function down to energies of ~100-200 MeV. Figure1: The scheme of the EOC of a particle beam (a) and unwrapped optical scheme (b) EOC [4] appeared as the symbiosis of enhanced emittance exchange and Optical Stochastic Cooling (OSC) [8][9][10]. These ideas have not yet been demonstrated.…”

We are proposing to test experimentally the new idea of Enhanced Optical Cooling (EOC) in an electron storage ring. This experiment will confirm new fundamental processes in beam physics and will demonstrate new unique possibilities with this cooling technique. It will open important applications of EOC in nuclear physics, elementary particle physics and in Light Sources (LS) based on high brightness electron and ion beams.

Optical stochastic cooling (OSC) is a promising technique for the cooling of dense particle beams. Its operation at optical frequencies enables obtaining a much larger bandwidth compared to the wellknown microwave-based stochastic cooling. In the OSC undulator radiation generated by a particle in an upstream "pickup" undulator is amplified and focused at the location of a downstream "kicker" undulator. Inside the kicker, a particle interacts with its own radiation field from the pickup. The resulting interaction produces a longitudinal kick with its value depending on the particles momentum which, when correctly phased, yields to longitudinal cooling. The horizontal cooling is achieved by introducing a coupling between longitudinal and horizontal degrees of freedom. Vertical cooling is achieved by coupling between horizontal and vertical motions in the ring. In this paper, we present formulae for computation of the corrective kick and validate them against numerical simulations performed using a wave-optics computer program.
