From this article, I learnt that lasers are powerful beams of pure coloured lights and we have used it for many years. The laser can save life or it can destroy life, it can be used for war or for knowledge. Throughout the years, man have harnessed the power of laser and now it is a major part of our life Without lasers, this blog post will not even be here. Certainly, laser has helped us a lot but how are we sure that we will not abuse it in the future.
One of the lasers uses is in nuclear power. Nuclear power is highly destructive and causes mass destruction, it is used in WW2 and the effects are still seen today. In the future, with more efficient lasers, more nuclear bomb may be created and some humans may give in to power and abuse the use of nuclear power. Scientist also predicted that lasers in the future will be 10 to 100 times as powerful as lasers today. Some people will certainly see this as a chance to use it in war and the damage it cause will be unprecedented. Now, we must learn how to respect the power of laser and not abuse it, we must learn what kind of destruction they will cause if they are abused and hopefully, our future will not be destroyed by lasers.
However, lasers are also a very beneficial tool if it is used for good. Now lasers are used to study the universe and measure huge distance in the universe. With the future improvement of lasers, we can go greater distance and continue to discover our solar system. It can also help us with more complex surgeries as the lasers improve, thus saving more life. If we respect the power of the laser, we will know how the harness its energy for better uses and soon, laser in the future will be a indispensable part of our life.
