Q-switched ND:yag

A Q-switched Nd:yag laser is a type of laser commonly used in medical and aesthetic applications. "Q-switched" refers to a technique that allows the laser to emit high-intensity pulses of light in very short durations. "Nd:yag" stands for neodymium-doped yttrium aluminum garnet, which is the crystal used as the laser medium.

Here are some key features and uses of Q-switched Nd:yag lasers:

  1. Wavelengths: The Nd:yaglaser typically operates at a wavelength of 1064 nm, and can also be frequency-doubled to produce light at 532 nm.
  2. High Peak Power: The Q-switched mode allows the laser to produce very high peak power, delivering energy in short bursts.
  3. Short Pulse Duration: The pulses are extremely short, often in the range of nanoseconds (billionths of a second), which helps minimize thermal damage to surrounding tissues.
  4. Penetration Depth: The 1064 nm wavelength has a deep penetration into the skin, making it effective for targeting deeper pigmentation and vascular lesions.


  1. Tattoo Removal: The high-intensity pulses break down tattoo ink particles, which are then naturally cleared away by the body's immune system.
  2. Pigmentation Treatment: Effective for treating various pigmentation issues such as melasma, age spots, and freckles.
  3. Vascular Lesions: Used for the treatment of vascular lesions like spider veins and hemangiomas.
  4. Skin Rejuvenation: Promotes collagen production and skin tightening, improving skin texture and reducing wrinkles.
  5. Hair Removal: Can be used for laser hair removal, especially effective for people with darker skin tones.
  6. Acne Scars: Helps reduce the appearance of acne scars by stimulating collagen production.


  • Precision: Targets specific areas without damaging surrounding tissue.
  • Safety: Suitable for various skin types, including darker skin tones.
  • Effectiveness: Provides significant results with minimal downtime.


  • Multiple Sessions: Often requires multiple treatment sessions to achieve desired results.
  • Side Effects: Possible side effects include redness, swelling, and temporary changes in skin pigmentation.
  • Professional Operation: Should be operated by trained medical professionals to ensure safety and efficacy.

Q-switched Nd:yag lasers are widely regarded for their versatility and effectiveness in both medical and cosmetic dermatology.
