Aleksandr Mikhailovich ProkhorovDied 8 Jan 2002 at age 85 (born 11 Jul 1916).Aleksandr Mikhaylovich Prokhorov is the Soviet physicist who received, (with Nikolay G. Basov, USSR and Charles H. Townes, US), the Nobel Prize for Physics in 1964 "for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle." "Maser" stands for "microwave amplification by stimulated emission of radiation." An amplification can occur only if the stimulated emission is larger than the absorption, requiring that there should be more atoms in a high energy state than in a lower one. This state is called an inverted population. Prokhorov had researched the maser independently but simultaneously with the other prize recipients. |
