Nd:YAG laser stands for Neodymium-doped Yttrium Aluminum Garnet laser. It is a solid-state laser used in various medical and cosmetic procedures. Here's a brief overview:
What is Nd:YAG Laser?
- Material: It uses a crystal of yttrium aluminum garnet (YAG) doped with neodymium ions (Nd³⁺) as the lasing medium.
- Wavelength: The laser typically emits light at a wavelength of 1064 nanometers (nm) in the infrared spectrum.
- Applications: It's commonly used for tattoo removal, hair removal, vascular lesion treatments, skin rejuvenation, and other dermatological and medical treatments.
Strength of Nd:YAG Laser
- Power: The strength of an Ndlaser can vary widely depending on the application and the specific laser system. In medical and cosmetic uses, power levels can range from a few watts to several tens of watts.
- Energy: For skin treatments, the energy delivered can vary based on the procedure. For example, in tattoo removal, the laser can deliver pulses with energy levels ranging from a few millijoules (mJ) to hundreds of millijoules per pulse.
- Pulse Duration: The pulse duration can also vary, with some treatments using long-pulsed lasers (milliseconds) and others using Q-switched lasers (nanoseconds) for more precise and powerful pulses.
The specific strength and parameters of the Nd:YAG laser are tailored to the treatment requirements and the patient's skin type and condition.
