Q Switched Nd Yag Tattoo Removal Machines , High Power Pico Laser Machine

The PicoSecond Laser uses ultra-short pulses (one trillionth of a second in length) to hit the melanin with 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 fewer 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.

Traditional nanosecond lasers predominately rely on photothermal action, delivering heat to the pigment and surrounding tissue. PicoSure takes advantage of Pressure Wave Technology to shatter the target ink into tiny particles that are easily eliminated by the body.

Ultra-short Pulse Duration Is the Difference

Picosecond pulse width is 100X shorter than nanosecond technology.
Only ultrashort pulse durations trigger the photomechanical effect.
With this short pulse width, half the fluence is required compared to Q-Switched nanosecond lasers.

At Picosecond laser pulse width, the generated photomechanical stress target pigment particle, making its volume expansion instantaneously and resulting in the breakup of the target into micro-particles, which is much easier for phagocytes to clear.

Q-switch laser has a 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 provides more effective and safer treatment than Q-switch laser.
