Simulation of laser-Compton cooling of electron beams for future linear colliders
Physical Review Special Topics. Accelerators and Beams, 2001 We study a method of laser-Compton cooling of electron beams for future linear colliders. Using a Monte Carlo code, we evaluate the effects of the laser-electron interaction for transverse cooling. The optics with and without chromatic correction for the

Cooling devices in laser therapy
Journal of Cutaneous and Aesthetic Surgery, 2016 Cooling devices and methods are now integrated into most laser systems, with a view to protecting the epidermis, reducing pain and erythema and improving the efficacy of laser. On the basis of method employed, it can be divided into contact cooling and non-contact cooling.
