Q Swiched ND YAG LASER

A Q-switched Nd:YAG laser is a type of solid-state laser that uses a neodymium-doped yttrium aluminum garnet (Nd:YAG) crystal as its laser medium. The "Q-switching" refers to a technique that allows the laser to produce very short, intense pulses of light, which can be useful for various applications. Key Features: 1. Wavelengths: The Nd:YAG laser typically operates at a primary wavelength of 1064 nm (infrared), but it can also be used to generate shorter wavelengths like 532 nm (green) through frequency doubling. 2. Q-Switching: This method involves controlling the "quality factor" (Q) of the laser cavity, which results in the release of energy in short bursts or pulses. This allows for high peak power and short pulse durations (usually in the nanosecond range). 3. Applications: Medical: Used in dermatology, ophthalmology, and dental treatments, including tattoo removal, skin resurfacing, and laser eye surgery. Industrial: For materials processing, marking, and engraving. Scientific: Employed in spectroscopy and research. The ability to deliver high-intensity pulses makes the Q-switched Nd:YAG laser particularly effective for applications requiring precise targeting of tissues or materials without causing prolonged damage.
