Fundamentally, the human energy of inertial confinement fusion laser drive from the nuclear fusion reaction, which happened on the sun "light fusion". Humans on Earth to achieve a controlled thermonuclear reaction, that is, the hydrogen bomb. To obtain an inexhaustible supply of new energy, this reaction must be continuously carried out under controlled conditions. There are two ways to achieve controlled nuclear fusion First, the scientists there are two ways to achieve controlled nuclear fusion tokamak open First, the scientists used the the tokamak open magnetic confinement fusion research is another proposed technical route in the early 1750s, another route in the early 20th century in the early 1960s, the exhibition "magnetic confinement fusion research. More details about high power laser pointer are necessary to be recorded in the log.
Magnetic confinement fusion research. Laser inertial confinement fusion laser inertial confinement fusion. The basic principles of laser inertial confinement fusion ICF (Inertial Confined Fusion ICF): using the powerful pulsed laser beam irradiation of deuterium micro-tritium fuel pellet in an instant high heat and great pressure, dense plasma is highly compressed before it spreads outward jet arising from the recoil of the inward implosion of pellet material is compressed to high density and high temperature required for thermonuclear burning, and to maintain a certain degree of confinement time to complete all of the nuclear fusion reaction, releasing large amounts of fusion energy. However, the conditions required by the fusion reaction is extremely harsh. Cost of Laser Pointers can be reduced to the lowest level.
Must first have a temperature of around 100 million degrees; involved in the response of the particle density is high enough to maintain a certain reaction time, ie 'nτ' value more than 1 million billion (sec / cm 3), which is well-known the Lawson criterion. Some countries, the laboratory has made a lot of basic research work in this type of laser device. United States, France has begun the construction of more large-scale giant lasers, expect to be able to achieve a laser thermonuclear ignition. China from the 1960s that began the study of inertial confinement fusion (ICF) and the Chinese Academy of Sciences and Chinese Academy of Engineering Physics from the 1980s, under the guidance of Wang Ganchang, Wang Daheng, joint research, the Shanghai-ray machines and Changchun-ray machines are cooperative unit. high power laser pointer can be standardized if necessary.
The early sixties, when the laser fusion research in China has just started, Qian Xuesen image to that: your cause is man-made a little sun on Earth! The key equipment in the ICF study is a high-power lasers. SG - I SG Ⅰ, 1964, a famous nuclear physicist Academician Wang Ganchang independently proposed laser fusion ideological, and suggested that a specific program in accordance with this Initiative, China's first laser Professional Institute - Chinese Academy of Sciences, Shanghai Institute of Optics The machine began the development and application of high power laser drivers in 1971, and deuterium - deuterium collisions of neutron. Chinese Academy of Engineering Physics and the Chinese Academy of Sciences to work together in 1978, ICF research into a new stage of comprehensive development. The design of high power laser pointer should be updated.
The past twenty years, committed to the development and application of neodymium glass laser drive - "SG" series devices, has made remarkable progress, and promote our inertial confinement fusion experiments and theoretical studies, and a place in the international arena. 1977, the Shanghai-ray machine using a 100 billion-watt laser system devices, inflatable glass shell targets irradiated nearly hundredfold body compression. Laser fusion research in China has entered an important stage of development of the step argument to the principle of implosion, and laid the foundation for future long-term sustainable development. In 1980, Wang Ganchang the proposal put forward to the construction of pulse power of 1 trillion watts solid state laser device, called a laser on the 12th experimental device (SG I). The loss caused by storage of high power laser pointer should be reduced to the lowest level.
