Laser energy is considered a stream of tiny particles of light called _______.

Laser energy is fundamentally understood as a stream of tiny particles of light known as photons. Photons are elementary particles that carry electromagnetic energy, serving as the basic unit of light and all other forms of electromagnetic radiation. When discussing lasers, it is important to recognize that these devices emit light through a process called stimulated emission of radiation, where photons are produced and amplified.

While electrons are negatively charged subatomic particles found in atoms, they do not specifically represent light energy. Waveforms can describe the characteristics of light waves but do not refer to the particles themselves. Quarks are fundamental constituents of matter, found within protons and neutrons, and are unrelated to the particle nature of light.

In the context of laser technology and phototherapy, understanding that laser energy consists of photons is crucial, as it relates directly to how the laser interacts with various tissues in the body, influencing therapeutic outcomes.
