A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light coherently. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers. Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum, i.e., they can emit a single color of light. Temporal coherence can be used to produce pulses of light as short as a femtosecond.

Among their many applications, lasers are used in optical disk drives, laser printers, and barcode scanners; DNA sequencing instruments, fiber-optic and free-space optical communication; laser surgery and skin treatments; cutting and welding materials; military and law enforcement devices for marking targets and measuring range and speed; and laser lighting displays in entertainment.
"Brain like a cloud, to define its core, but it is difficult to determine the edge," 7 Broadcasting British Corporation quoted as saying Geydaniel Oring researchers. In the treatment of other cancers, doctors may be able to remove some of the surrounding areas of the tumor to prevent recurrence of cancer, such as colon cancer. However, the human brain is not related to tumor resection, the question of how much extra sensitive.

Oring said, SRS microscopy can make resection of tumor surgery "more efficient, safer and more accurate". The findings are published in the British Journal of natural and biomedical engineering. As for this kind of operation can enhance the survival rate of cancer patients, at present can make nothing of it.
The fourth session of the Sino British ministerial energy dialogue "on October 18th -21, held in London, China Power Construction Group owned Hydropower Institute and the British Renewable Energy Office jointly signed the" Sino British offshore wind power industry cooperation Steering Committee cooperation agreement ".

The dialogue Chinese National Energy Bureau and the UK energy and climate Department signed a memorandum of understanding on cooperation in energy, relevant enterprises signed 5 cooperation agreements in offshore wind power, nuclear power and other areas of civil. When the diplomatic relations between China and Britain into the golden age, the energy dialogue will be a comprehensive cooperation between the two countries in the field of energy to a new climax.

The dialogue will be co sponsored by the China National Energy Administration and the British Ministry of energy and climate change, the delegation participated in the energy reform, nuclear energy, wind power, new energy technology four sub forum. In the offshore wind electricity new energy forum, the national energy board secretary Zhu Ming, deputy director of the Department of energy and climate, clean energy secretary Michael Rutter attended the meeting and delivered a speech. Vice President Yi Yuechun Hydropower Institute keynote speeches, introduced China's offshore wind power development and cost reduction trends, opportunities and challenges.

The two sides jointly set up in the British offshore wind power industry cooperation Steering Committee, the next step, the two sides will be in charge of the energy sector between the two countries under the guidance of the cooperation agreement is a framework based on accelerating the development of wind power industry, comprehensive and pragmatic promote the Sino British offshore wind power industry cooperation, and open the huge investment opportunities for the industry.

Fweek laser network news: according to Market Research Report "the latest release of 20162022 global laser processing market forecast shows that by 2022, global laser processing market size is expected to reach $9 billion 750 million, achieved during the 6 years CAGR of 6.13%.

During the forecast period, the Asia Pacific region will occupy the largest share of the global laser processing market. With the rapid development of new applications and automation, China, Japan and South Korea will become the main market for laser applications.

In 2016, the laser industry presents the development trend of optical fiber laser, picosecond, femtosecond laser technology and laser processing. Laser precision microfabrication obtained more and more applications in the new energy, information technology, bio medicine, new materials, electronics and aerospace industries, including precision drilling, reticle, slotting, surface texture, surface modification, modification, repair, cleaning, increasing material manufacturing process. In addition, the concept of intelligent manufacturing, new energy provides a good environment for the development of lasers.
