Summary

The laser was invented in 1960, and at that time, it was expected to bring about a revolution in electric communication due to its high frequency. Research on lasers began worldwide, including in Japan, with the goal of developing new technologies. The author, Tadashi Takahashi, was involved in the development of lasers at Toshiba and recalls the difficulties they faced in creating the first lasers, including the ruby laser, GaAs semiconductor laser, and He-Ne laser. The author notes that the first researchers to successfully create a laser, such as those at Bell Labs, faced significant challenges and had to overcome numerous obstacles, including the "threshold" barrier. Today, lasers are widely used in various fields, and the author encourages young researchers to take on new challenges and continue to develop new laser technologies.
