What are the positive and negative impacts of Lasers?

Lasers have numerous positive impacts, including their use in medical procedures (such as eye surgeries and cancer treatment), industrial applications like cutting and welding, and advancements in communication technologies (like fiber optics). However, they also pose negative impacts, such as potential harm to eyesight if misused, risks of skin burns, and concerns over safety in public spaces. Additionally, the proliferation of laser technology can lead to misuse, such as in laser pointers being directed at aircraft or other vehicles. Overall, while lasers have transformative benefits, they require careful management to mitigate risks.
