A Ruby Laser is a type of solid-state laser that uses a synthetic ruby crystal as its gain medium. It emits a deep red light at a wavelength of 694.3 nanometers and is known for its high-intensity, coherent light. This laser is often used in dermatology for treatments like tattoo removal and hair reduction, as well as in scientific research for its precise and powerful beam.
