To Probe Into The Process Of The Naissance And Forepart Development Of Laser Physics

This dissertation is to probe into the process of the the naissance and forepart development of Laser Physics.Afterl95Os,due to the development of quantum electronics,a new embranchment appeared ,which is laser physics,it抯 also called the physics of quantum transitions because of the emanation of electronic technology. The symbol of laser physics is the Noble Physics Prize in 1964. The naissance of laser physics is the landmark in the cognition of naturalness. Laser physics is compositive synthesis of the quantum theory, wireless technology, microwave spectroscopy and solid physics,and it抯 also the brilliant production of close-knit combine in science and technology, theoretics and practice.After the naissance, the developments of laser physics emerge rapidly,our living, behavior and concept were affected and influenced by laser. From gestation to naissance and development, the road of laser physics is very flexural,the creations and brightnesses of multitudinous scientist were agglomerated. Probe the naissance of laser physics. Summarize historical experience, it is helpful for the realization to the understand in naissance course of modem technology and the research in laser physics.This dissertation is divided into four parts. In the first part, the paper mainly discourse upon the gestation course of theoretic base in laser physics, stimulated emission, population inversion and other basic theory of laser were discussed. In the second part, I briefly probe the naissance of laser physics based many original literatures. Depict the naissance , content , the infection to laser physics of microwave spectroscopy. Clarify the innovation, breakthrough and accomplishment of C.H.Townes (the outrunner of laser physics)in his maser invention. Probe the course of the movin~ to optical frequencies, put forth the idea for mode selection of Townes and Schawlow, which is the uppermost difficulty in the invention of laser. Discourse upon the naissance process of Maiman S first ruby laser and the apocalypse to us in Maimans success. In the third part, the development ,applications and effect of laser technology are introduced in the fore twenty years (1960抯?970抯)in the naissance of laser physics. The fourth part is the sum-up and review to the naissance and development of laser physics. the paper mainly sums up the job of Townes and Schawlow. Probe the postponed causation and the impetus of laser physics. Simply analyse the infection to the development of morden technology, limit to length, the development of laser technology in China is put in the finality of this dissertation.
