-- From Dr. John Tsai, President

Dr. John Tsai, is the founder and president of Excel Precision Co.. Dr. Tsai got his Ph.D. Degree from Stanford University, supervised by Professor Arthur Schawlow.

... when the first lasers were operated, I and other scientists close to the research were surprised at how easy it turned out to be. We had assumed that, since lasers had never been made, it must be very difficult. But once you knew how, it was not at all difficult. Mostly what had been lacking were ideas and concepts.

-- Professor Arthur Schawlow

Professor Arthur Schawlow is the co-inventor of the Laser and a Nobel Laureate (1981, Physics). Professor Schawlow is a director of Excel and a member of the faculty of the Physics Department at Stanford University.
