Looking back at the laser industry in 2018, it can be described as turbulent. There are both research awards and new developments in the company's layout, and two people who have had a major impact on the industry have left us. Let's review the top ten hot events in the laser industry in 2018.
Laser technology won the award again
On October 2nd, Beijing time, the Royal Swedish Academy of Sciences decided to award half of the 2018 Nobel Prize in Physics to American scientist Arthur Ashkin for its invention of Opitcal tweezer technology, and the other half to French scientist Gerard Mourou and Canadian scientist Donna strickland. In recognition of their invention of a method that can be used to generate high-intensity ultrashort optical pulses, namely chirped pulse amplification (CPA). Among them, Canadian scientist Donna strickland is the third woman to win the Nobel Prize.
The light tweezers use a force field generated by a focused beam to capture tiny objects, like a scorpion, so in particulate matter, micro-nano science, and Research fields such as biology and medicine have been widely used.
Chirped Pulse amplification is used to generate high-intensity, ultra-short laser pulses. The current laser single pulse can reach petawatt (1015 watts) or more, and the pulse width can reach the femtosecond (10-15 sec) level in the laboratory. Can do a second (10-18 seconds). High-intensity, ultra-short laser pulses not only have important industrial and military applications, but because they can reduce the single-pulse time domain to around 10-18 seconds, such time-resolving power opens up the study of ultrafast processes at the atomic and subatomic levels. Possibly, its impact on the underlying physics is immeasurable.
Comments: This time the Nobel Prize in Physics is awarded to scientists in the field of lasers. It is an encouragement to scholars in the field of laser physics and laser technology, and also an encouragement to the laser industry. The new laser technology will bring many industry standards and will bring more solutions to industry problems.
China's laser film components in the international competition
On October 9th, Lawrence Livermore National Laboratory sent the laser damage threshold of fundamental frequency laser reflective film elements in 2018. International competition results: Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Chinese Academy of Sciences, Key Laboratory of Laser Materials, Thin Film Optics The laser reflective film components developed by the laboratory have once again won the advantage. Compared with the wins in 2012 and 2013, the advantage is more obvious: the damage threshold is 20% higher than the second. The Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences released the information on the 10th.
The high-power laser reflective film is an indispensable component of a strong laser system such as a laser fusion device and a super-ultra-short laser. It is the only one that can force a strong laser that only knows the straight line to follow the human mind. element! It not only needs to withstand the impact of high-energy lasers, it guarantees that high-power laser devices will not “self-injury”, but also “directs” the direction of the lasers so that the laser light incident on its surface will go in order according to people's wishes. The same target. The laser damage threshold represents the ability of the component to "control command" the laser, and its magnitude determines whether the laser energy can reach the target without damage.
Comments: It is undeniable that China has not been able to achieve independent research and development of all core technologies, but after decades of development and catch-up, the local “local” is constantly expanding.
Raycus laser is on the market, domestic lasers are coming to a new stage
On the morning of June 25, Wuhan Raycus Fiber Laser Technology Co., Ltd. was held on the Shenzhen Stock Exchange, marking the opening of the capital road and entering a new stage of leaping development.
The Semiconductor Laser Innovation Institute was established, and the high-power laser "with no core" will become history.
On March 15th, at the Shanghai New Expo Center in Shanghai, Suzhou EVERBRIGHT Optoelectronic Technology Co., Ltd. and Suzhou High-tech Zone Management Committee signed an agreement. The two sides will invest 500 million yuan to build a semiconductor laser in the high-tech zone. Innovative Research Institute aims to use the advantages of existing high-power semiconductor laser chips to expand the application direction and field of laser chips, and attract more talents to break through the difficulties of high-power laser chips.
The death of Academician Chen Chuangtian has caused the United States to suffer the embargo
At 9:57 on October 31, 2018, Mr. Chen Chuangtian, an outstanding member of the Communist Party of China, a famous material scientist, academician of the Chinese Academy of Sciences, academician of the Third World Academy of Sciences, and researcher of the Institute of Physics and Chemistry of the Chinese Academy of Sciences, died in Beijing due to invalid medical treatment. At the age of 82.
Industrial laser pioneer and former president of TRUMPF Group, Professor Lebinger passed away
On October 16, 2018, Professor Berthold Leibinger, the industrial laser pioneer and former president of the German Trumpf Group, died in Stuttgart, Germany due to long-term illness. Mr. Leibinger joined the company as an apprentice in 1950. In 1966, he became a partner and served as a managing director until his retirement from management on November 18, 2005. As the technical director, CEO and chairman of the board of directors, he has led Trumpf for more than 40 years. He is a recognized pioneer and leader in industrial laser applications, and has made outstanding contributions to the practical application of lasers from laboratories to industrial applications.
On April 26th, US time, Enna was listed on the NASDAQ Global Select Market, and the initial public offering of 6 million shares of common stock was issued at $16 per share. The initial offering was completed on April 30th.
II-VI acquires Finisar
On November 8, US time, two optoelectronic device giants in the United States announced the merger. II-VI, the global leader in engineering materials and optoelectronic components, and Finisar, the global technology leader in optical communications, announced that they have reached a final merger agreement. II-VI will acquire Finisar in cash and stock trading with an equity value of approximately 32. One hundred million U.S. dollars.
The laser angle reflector rises with the bridge and is intended to detect gravitational waves
At 5:28 on May 21, China used the Long March 4 C carrier rocket at the Xichang Satellite Launch Center to successfully launch the lunar exploration project No. 4 mission. On this relay star, a laser corner reflector developed by the Chinese Academy of Sciences and the president of the University of China, Luo Jun, has been carried out for three years, and it is planned to conduct a pure reflection laser ranging experiment for the first time in humans beyond the Earth-moon distance. Take the first step of the gravitational wave detection "Tianqin Plan".
Laser TV will drop to 70 inches
In May of this year, Hisense launched the world's first popular laser TV L5, with a huge size of 80 inches and a high-grade optical light curtain price of only 19999 yuan. This price is even lower than the price of many 2K laser TVs. It has successfully opened the door to the popularity of laser TV 4K, and opened up the offensive of large-screen LCD TVs of 65 inches and above.
