My best friend's name is Andrew. We've been friends since kindergarten. Andrew has got blue eyes and blond hair. He is taller than me. He is cheerful and he is slow to take offence. Andrew doesn’t allow anyone to insult other people. We have a great deal in common, we listen almost to the same music and we regularly play table tennis after school. We always find interesting topics to discuss. Very often we visit each other at home. We always can help each other with homework, and we usually play computer and video games together.

“Thank you so much for inviting me to interview for your open account specialist position. I truly appreciate the time you took to talk with me about this opportunity and the company. I enjoyed learning more about your work group and how I might fit into that team. Please don’t hesitate to contact me with any follow-up questions you might have. I hope to talk with you again soon.”

It was Newton who formulated the basic concept that light from ordinary sources is complex. By "complex" he meant that such light could be analysed into colours and the colours could be used to synthesize light.

How does laser light differ from ordinary light? In brief, it is much more intense, directional, monochromatic and coherent.

We know the light emitted by an ordinary source such as candle or an incandescent lamp to consist of uncoordinated waves of many different lengths, that is, it is incoherent and more or less white.

The scientists found the waves of laser light to be coordinated in space and time and to have nearly the same length. This coherence and chromatic purity and also intensity of laser light result from the fact that in a laser excited atoms are stimulated to radiate light before they have had time to do so spontaneously and independently. The directionality of laser light arises from the geometry of the laser. These properties of laser light suggest many uses for it both in technology and in physics. The scientists consider laser light to be different from ordinary light even when it merely illuminates a surface. The surface looks grainy and sparkles.

By means of some instruments it has become possible to examine materials and physical phenomena in new ways. Among the most interesting applications of the laser the probing of materials by the study of their scattering of light should be mentioned.

The laser is being applied to probe the internal structure and behaviour of molecules by examining the light-scatter­ing phenomena. Many investigators are working at the development of coherent light sources, those ones whose wave-length can be changed. Many amplifiers and oscillators have been constructed for this purpose lately.

Laser light is applied in many fields such as medicine, biology, industry and so on. We can say scientists made laser light serve man.

The scientists found the energy density of the image formed by a lense in a laser beam to be used to heat, melt or even vaporize small areas of any material. Laser is also used to pierce holes in diamond.

Nowadays laser can be used to cut a wide range of materials including wood and paper.
