When people talk about an Alex Laser, they are referring to a device that uses an alexandrite crystal to produce the laser source. This laser produces light at a specific wavelength, which is in the infrared spectrum (755 nm). It is categorized as a red light laser, and it is also available in Q-Switched mode. When the laser is in Q-Switched mode, the laser is able to produce a high-intensity beam for a very short amount of time, which can improve the treatment process. When this laser is used, the light emitted by the laser is then converted into heat energy. The laser induces a specific effect called photo thermolysis. The combination of heat and light will destroy diseased cells, helping people recover while preserving healthy tissue.
