日本でも 青色ダイオードで 受賞者が複数出ましたが､光というのも 興味の尽きない分野ですね｡
今回は レーザーです｡
 Physics Laureate Charles H. Townes.
The Laser - One of Our Great Light Sources
The
United Nations has proclaimed 2015 as the 'International Year of
Light'. A laser provides a very precise light, crucial in many daily
activities, like using a printer or scanning items in a store. The
technology is also used in communication, industry, medicine and
environmental care. Charles H. Townes, who passed away in January, 99
years old, was awarded the Physics Prize for the fundamental work that
led to the construction of lasers. In this video clip, he recalls the
moment of eureka conceiving his idea of maser, a similar appliance for
microwaves.  Watch the video clip |

Laser-Guided Research
The
first functioning laser was constructed in 1960, and since then
developments have been rapid. Nicolaas Bloembergen and Arthur L.
Schawlow together received 1/2 of the 1981 Physics Prize for their
contribution to the development of laser spectroscopy. In this video
interview Nicolaas Bloembergen talks about his work on nonlinear optics
and its applications. Watch the interview |

"It Just Seemed Like a New World that I Wanted to Explore"
Half
of the Nobel Prize in Physics 2005 was awarded to John Hall and Theodor
Hänsch, who achieved a previously unattained precision in laser
spectroscopy. Hear Theodor Hänsch recall his first encounter with a
laser. Watch the video clip |

The Laser Challenge
No
one knew what laser would be used for when it was discovered. Today,
laser use is applied in several areas, such as research, communication,
and environmental and medicine care. Learn more by playing the Laser

The Foundation of the Laser
The
acronym LASER stands for Light Amplification by Stimulated Emission of
Radiation. In 1917, the foundation of laser was established when a
Nobel-Laureate-to-be introduced the concept of stimulated emission. Who
was it?
