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.


How has lasers evolved over time?

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.


Are there any lasers that can cut through metal?

Yes, there are lasers specifically designed to cut through metal. Fiber lasers and CO2 lasers are commonly used in metal cutting applications due to their high power and precision. These lasers are capable of cutting through various types of metals with different thicknesses.


What is the difference between lasers and tunable lasers?

All tunable LASERs are LASERS, however not all LASERS are tunable. In a tunable laser the lasing medium, which is typically a gas, dye or crystal, can be altered to produce slightly different frequencies, thus allowing the laser to be 'tuned' or frequency changed where most LASERS produce a very narrow band of radiation frequencies.
