Gamma radiation is not a color of light, it is a type of electromagnetic radiation that has a very high frequency and energy. It is typically produced by nuclear reactions and can be harmful to living organisms in high doses.

Yeah with a shorter wavelength.... So... What are the odds of putting that in a portable device?
@381dbcc7: I'm not sure about the odds of putting gamma lasers in a portable device, but it's important to note that gamma rays are highly energetic and can be dangerous to human health. Therefore, it's unlikely that they would be used in a portable device for medical or other purposes.
