Lasers are useful for a lot of things could be bad or good
For example people use laser for hair removal which is good but effects cultures that don’t remove hair due to religious reasons
Another way people use lasers is for war people use lasers to aim better which is bad because that allows military to kill people
People can open up businesses for laser eye surgery, laser hair removal, laser engravings, etc. which is a good way to make money and to benefit customers
Lasers aren't only used in warfare and surgery but in DVD players and bar code scanners
Lasers are used in science a lot
For example Nasa uses lasers to calculate cloud coverage and water vapor on earth
Lasers can also be used to generate energy through nuclear fusion
To make a nuclear fusion you need really high temperatures which can be created by highly powered lasers
Lasers are actually light thats is reflected of an mirror which the goes through a energy source and through a crystal to change its color so a red laser is created through a medium which contains helium and neon to make a red ray
Lasers are also used in space missions. For example mission breakthrough starshot which sends out 1000 little spaceships that are 3.5 cm big and have 4 x 4 meters of solar sail attached to them are sent out to alpha centauri (closest star system to us at the moment). The little spaceships will reach alpha centauri in just 20 years by traveling at the 20% of the speed of light which is the fast we have ever gotten
The reason why that is possible is because high powered lasers are attached to the solar sail which let out a lot of energy and allow the spacecraft to reach 20% of the speed of light in just 10 minutes this concept is known as beam sailing
Some of the legal consequences for lasers include…
Lasers of any power aren’t banned
A laser pointer cannot be laser pointer if it is stronger than 5 milliwatts
if vendors sell lasers that are stronger than 5 milliwatts and call them lasers that is illegal
Lasers are desirable globally, country, region, company, immediate neighbors, and people in general
Lasers are almost in everything its desirable globally due to the major advancements in laser technology. For example what is said above about the breakthrough starshot will be a huge landmark for mankind and will uncover a lot and may answer questions like “is there life in space”
It's also desirable by countries because of the the advancements in the medical field and more surgeries depend on lasers which means if your country doesn't have lasers they won't be able to provide you with the best surgery's and the highest level of health care.
Lasers do not affect the environment but are used to predict what's going to happen in the environment
Nasa for example uses lasers to calculate cloud coverage and water vapor on earth which is very important because they can predict how much it will rain or will it rain
Lasers affect me in the long term and the short term
They allow me to buy items bar code scanners use lasers to scan and allow me to find out the price of a item and buy the item
Lasers also allow me to watch movies using a disc and listen to music in my car CD and DVD players use lasers to scan the data and send it out to me as music or a film
Lasers affect me in the long term because when I get old and surgery or i'm losing my sight i can get laser eye surgery which will allow me to see and live longer
