Cold lasers are low-level lasers that do not produce heat and are used for therapeutic purposes such as reducing inflammation and promoting healing. Hot lasers, on the other hand, are high-level lasers that generate heat and are used for cutting or cauterizing tissue in surgical procedures.

Is there a difference in weight between hot air and cold air?
Yes, there is a difference in weight between hot air and cold air. Hot air is lighter than cold air because the molecules in hot air are more energetic and spread out, decreasing the overall density of the air. This difference in weight is a factor in phenomena such as convection currents.
How does hand tell difference between hot and cold objects?
The hand detects temperature through nerve endings called thermoreceptors. These receptors send signals to the brain when they come into contact with hot or cold objects, allowing us to perceive the difference in temperatures. Our brain then processes this information and gives us the sensation of feeling hot or cold.
