Geoffrey Perryes and surveys research of current thinkers and experts in t.Photonics and nonlinear optics are important areas of science, engineering and technology. One of the most important ultrafast nonlinear optical processes is the supercontinuum (SC) – the production of intense white light pulses covering:

Implications of a Comprehensive Test Ban for a Stockpile of Nuclear Weaponswould form a supercritical assembly, are brought rapidly together without changing their shape or density. Another is the implosion method, in which high explosive is employed to reduce the volume of an assembly that is already nearly critical.
