When was the Ruby crystal laser invented?

1955
1960
1965
1970

The correct answer is: 1960

The Ruby crystal laser was invented in 1960 by Theodore H. Maiman. This option is correct because it aligns with the historical timeline of when laser technology was being developed and commercialized. Option A, 1955, is too early as it predates the development of the first laser in 1960. Option C, 1965, is close, but still after the invention of the Ruby crystal laser. Option D, 1970, is too late as it occurred after the commercialization and widespread use of the Ruby crystal laser. Therefore, option B is the most accurate and logical choice.
