Laser light in dentistry is a unique, non-ionising form of electromagnetic radiation that can be employed as a controlled source of tissue stimulation, cutting or ablation, depending on specific ...

Ordinary light can be a mixture of many wavelengths. It is these differences that make the laser beams useful and potentially hazardous. Lasers produce non-ionizing radiation, which is less ...

Examples are gamma rays, x-rays, CAT scans and ultraviolet light. In contrast, non-ionizing radiation does not have enough energy to alter the electron structure; however, it may be harmful ...

Terahertz waves, known as non-ionizing radiation ... used a 150-terawatt-class Ti:sapphire laser to convert optical energy into terahertz radiation (so-called optical rectification) in lithium ...
