Laser cavity when laser can produce high voltage pulse xenon lamp and YAG crystal bar.When laser xenon lamp injection of xenon lamp light after a certain amount of energy, stimulate the YAG crystal rods to launch the 755/1064/532 nm laser, polaroid is emitted laser unified to the same direction, make the emitted laser single better.After laser in the laser cavity, before the mirror, mirror of the laser resonant part, after short time trigger Q crystals, again after two 45 degree mirror reflection by emitting laser light arms.In the process of laser xenon lamp in the light of have a large amount of heat produced; After water circulating system will be hot. Commonly known as the light arm joint arm： Laser smooth is convergent laser focus, focus spot diameter of 2 ~ 10 mm. When laser gathering isometric point contact with the skin convergence focal spot diameter is 1 mm, when not in contact with the patient position, adjust the laser convergence
isometric point and the distance between the patients with skin is adjust convergence focal spot diameter, adjusting the laser gathering isometric point and the distance between the patients with skin range from 0 to 3 mm, the corresponding convergence focal spot diameter for adjustment, in 2 ~ 10 mm distance after short of effective treatment.Laser light launched into mouth will into the laser light arm inside, and then use locking device lock base According to the operator of the handle, can adjust the center of gravity of light arms, appropriately adjust the way as the center of rotation of the adjustment block fixed nut！
Treatment principle:
The PicoSecond Laser uses ultra-short pulses (one trillionth of a second in length) to
hit the melanin with a great pressure, the melanin shatters into tiny dust-like particles. Because the particles are so small, they are more readily absorbed and eliminated by
the body. This can mean better clearance of the melanin and less treatments overall. PicoSecond Laser is a quick and easy non-surgical, non-invasive laser skin treatment
for the body including chest or decollete, face, hands, legs, and more. Picosecond laser VS Q-switch
At Picosecond laser pulse width, the generated photomechanical stress target pigment
particle,making its volume expansion instantaneously and resulting in breakup of target
into micro-particles, which is much easier for phagocytes to clear. Q-switch laser has
pulse width of 5ns or more, its photomechanical stress is not efficient compared to
picosecond laser, it creates large particles, and with long pulse width, scattering energy
goes toward surrounding tissue,resulting in risks of thermal damage. Therefore, Picosecond laser provide a more effective and more safe treatment than
Q-switch laser.
