Lasers have evolved over time in terms of increased power and precision, allowing for applications in various fields such as medicine, communication, and manufacturing. Advances in technology have led to the development of new types of lasers, such as fiber lasers and diode lasers, which are more efficient and versatile. Additionally, the miniaturization of lasers has enabled their integration into devices such as smartphones and laptops.

How can lasers travel so far nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn?
Lasers can travel far distances because they are highly directional and can maintain their focus over long ranges. Additionally, lasers do not disperse as much as other forms of light, allowing them to stay concentrated over a long distance. This makes them useful for a variety of applications such as communication, ranging, and cutting.
Lasers emit what kind of energy?
Monochromatic, coherent, electromagnetic energy tuned over a wide range of frequencies/wavelengths.
Why we prefer 4 level laser to 3 level laser?
We prefer 4 level lasers over 3 level lasers because they typically have higher efficiency due to the additional energy level for the pumping process. This allows for lower threshold energy for lasing and better population inversion. Overall, 4 level lasers tend to have better performance characteristics compared to 3 level lasers.
What is the difference between cold and hot lasers?
Cold lasers are safer and deal less pain than hot lasers. Cold lasers are usually used for repairing skin damage and treating pain and inflammation. Hot lasers are simply used for burning things.
How are white lasers different from traditional lasers in terms of their functionality and applications?
White lasers are different from traditional lasers because they emit light across a broad spectrum of colors, while traditional lasers emit light of a single color. This allows white lasers to be used for a wider range of applications, such as in lighting, displays, and medical imaging, compared to traditional lasers which are typically used for precision cutting, welding, and communication.
