Information

The q-switch nd-yag laser treatment device is a laser treatment device that uses lasers to treat pigment spots and remove tattoos. The q-switch nd-yag laser treatment is a non-invasive or minimally invasive, high-safety treatment method.
  The q-switch nd-yag laser treatment instrument is a solid-state laser system that uses Nd: YAG (neodymium-doped yttrium aluminum garnet) crystal as the laser working material and pulsed xenon lamp as the pump source. Driven by the laser power supply , the xenon lamp emits strong pulsed light, and the laser crystal absorbs the pulsed light to achieve laser energy accumulation, and then establish laser oscillation in the resonant cavity, and finally output 1064nm pulsed laser through the output lens. The role of the electro- optical Q switch here is to compress the pulse width of the 1064nm laser to the nanometer level, while increasing the peak power density of the laser, so that the laser instantly emits a high-power and high-energy density laser beam.
 The q-switch nd-yag laser series includes different output pulse energy, 5-24ns output pulse width, different divergence angle and repetition frequency. They are usually equipped with built-in or external frequency multipliers to achieve 1064nm, 532nm, 355nm, 266nm, 216nm wavelength conversion. In some laser models, a mirror with a variable reflection coefficient can be used to provide good beam quality and good harmonic conversion. Variable reflection coefficient mirrors are used in some laser models, which can provide good beam quality and harmonic conversion effects . The double-pulse q-switched laser has a precision delay of 1 ns between two output pulses, and can be used for laser spectroscopy and speed measurement. The reliable and stable q-switched laser is easy to operate, with convenient remote control and computer interface.
  The q-switch nd-yag laser treatment system adopts Nd: YAG laser and advanced laser Q-switch technology and laser frequency doubling technology. Using the principle of instant photo-blasting, the laser is released in a very short time (about 10ns) to form Giant pulse with high energy density. The pigmented tissue is swelled rapidly after being impacted and heated by the laser, and fragmented into tiny particles, which can be swallowed and absorbed by macrophages in the human body.
  Trial application of low energy density, large spot q-switched nd-yag laser to the clinical treatment of melasma, and achieved good short-term effects. It can be seen from the results that the effective rate can reach 80%, the recovery rate can reach 20%, and the incidence of adverse reactions is low. The basic principle of the q-switched nd-yag laser in the treatment of spot diseases is: the Q-switched laser can release huge energy to the target tissue in an instant, causing the target target, that is, the pigment particles of chloasma to be crushed into very small particles. It is then cleared by macrophages in the patient's tissues without damage to the surrounding tissues. Studies have shown that there is no significant difference in efficacy of Q switch in treating epidermal, dermal, and mixed melasma.
  In short, the low-energy density, large-spot q-switch nd-yag laser has good short-term curative effect in the treatment of chloasma with small side effects. It is an effective method for external treatment of chloasma in clinic, but its effectiveness has a deeper effect. The relationship between mechanism, curative effect, side effects and energy density needs to be further studied from basic research, and the long-term curative effect needs further observation.
