On May 16, 60 years ago, Theodore Maiman, a 32-year-old engineer, turned a switch in the Hughes research laboratory in California to generate a beam of light from a single crystal of pink Ruby (Cr: Al2O3). This laser with a wavelength of 0.6943 μ m is the first laser ever obtained by human beings.
In the past 60 years, known as "the fastest knife, the brightest light, and the most accurate ruler", laser has played an important role in various fields of social life and become an important tool to support the development of the national economy.
In order to commemorate the "60th anniversary of laser invention", one of the online commemorative activities jointly held by Optronics, Wuhan Optical Expo, e-optics, and China laser magazine, it is the round table discussion on the comments of ultrashort pulse laser at home and abroad.
