Summary form only given. High power 1550 nm InGaAsP/InP single-frequency distributed-feedback lasers with record output powers are reported. Ex-facet power levels of 440 mW and single-mode fiber power ...

This high grade works in nuclear weapons because it can sustain a fast, uncontrolled chain reaction, which releases a large amount of energy compared with the other isotopes. Uranium’s varied powers ...

Uranium-235 is an isotope of uranium, which is a version of an element that has the same basic identity but weighs a little more or less. Think about apples from the same tree. Some are big and ...

So, the enrichment process concentrates uranium-235. Enrichment can make uranium more useful for the development of nuclear weapons, since natural uranium doesn’t have enough uranium-235 to work well ...
