Today the world has entered the 21st century and it has shown the world a vast difference as
compared to the earlier eras. Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical efforts in order to achieve some values.Technology refers to the tool and machines that may be used to solve real world problems. It is a far reaching term that may include simple tools, such as a crowbar or wooden spoon, or more and more complex machines, such as space stations.Tools and machines need not be material but the virtual technology, such as computer software and business methods,fall under this definitions of technology.The word technology can also be used to refer to a collection of techniques. In this context, it is the current state of humanity's knowledge of how to combine resources to produce desired products to solve the problems, fulfill needs, or satisfy wants: it includes technical methods, skills processes,techniques,tools and raw materials. When combined with another term such as "medical technology" or "space technology" it refers to the state of the respective fields knowledge and tools. "State of the art 'refers to the high technology available to humanity in any field.Technology can be viewed as an activity that forms or change culture.Technology is the application of math ,science and the arts for the benefit of life as it is known.A modern example is the rise of communication technology, which has lessened barriers to human interactions. Life seems to be full of excitement and relief due to these technologies. There is saving of time due to use of these techniques and also the work seems to be completed fast and attractive. Living Standard of the people has raised up due to these technologies. So, we should use them properly and should be thankful to those who have made our life so comfortable that we can live tension free. Misuse of the technologies can lead to the destruction of the invention as well as civilization but proper utilization can lead to the development of the country and increase in the status of living in the society.

Introduction toTechnologies
For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.
Laser Technology
The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom
Science and technology has provided us numerous miraculous discoveries 
and devices. Lasers are its most modern achievements. Lasers are defined as the devices which produce pure and intense beams of light or radiation. They were invented in 1960. At the time of invention ,nobody knew what to do with them but today they are widely used in many sectors tremendously. Especially in the field of industry they are used for cutting clothes,piercing leather and even hard substances like diamond and metals also are used for cutting bricks and granites. They are also used in transport and communication:for example,they are used instead of cables in telecommunication, and are used in flight simulations to train pilots. In the field of medicine,lasers have made revolution. Lasers are used to destroy the single cell of living tissues in the treatment of cancer. Doctors have been using lasers instead of surgical knives in major operations. Skin blemishes can been removed by the help of lasers. Lasers helps to control pollution.They
are useful for measuring the size of pollutant particle in the air. They can also be useful for clearing up oil slicks on the surface on the seas. They can also be useful for measuring the distance between the two useful objects such as between earth and moon. Thus it can be said they they are useful in the field of medicine,pollution control and measurement.Because of the advantages mentioned above lasers are completely beneficial.Unfortunately, lasers can be used in the means of wars. It is just misuse of them. They can be mercilessly used to kill human beings: that's why they are also called "Death Rays". In the wars they are used in guiding missiles and finding range for gunners. It is the exploitation of lasers,and in this sense, they invite demerits and ruins. But if properly used , they can bring development in the human civilization. It is wise of human beings not to invite any collision courses of human civilization.
