The Picosecond Laser and Q-Switched Nd:YAG Laser are both highly effective cosmetic solutions for tattoo removal, offering quick and precise results. The choice of which method to use when removing a tattoo can be just as hard as picking the perfect outfit for a special occasion. So, which aesthetic laser should we opt for? Picosecond lasers, often referred to as Pico Lasers, are advanced laser systems utilized in medical and aesthetic procedures. They emit ultra-short pulses of light measured in picoseconds (trillionths of a second), allowing for precise treatment with minimal damage to surrounding tissues. How Pico Laser Works: Pico lasers emit very short pulses of energy that impact the targeted area without generating significant heat. The powerful impact of the picosecond laser effectively shatters unwanted skin pigment or particles into smaller fragments. These fragments are then naturally cleared by the body’s immune system, which minimizes the risk of thermal damage to surrounding tissue.Picosecond Laser
In the field of tattoo removal, the Q-Switch nanosecond laser was once considered the gold standard. Q-Switch technology generates powerful energy by temporarily inhibiting the release of light and then suddenly releasing it. You can imagine water rushing down a river. Although it is very powerful, if you temporarily block the flow with a dam and then release it, the impact of the water will be stronger. This is exactly how the Q-Switch laser works.
Most Q-Switch lasers use nanosecond pulses, with a pulse duration of 1 nanosecond (a billionth of a second), while picosecond lasers use picosecond pulses (a trillionth of a second). Although there seems to be little difference in time units, in practical applications, the effect of picosecond laser is more significant. Although the name "picosecond" lasers imply that they use extremely short pulses, in reality, many picosecond lasers do not achieve true picosecond speeds.
In the field of tattoo removal and skin treatment, Q-Switched Nd:YAG laser and Picosecond Laser have many similarities in application, but there are some key differences between them:
Q-Switched Nd:YAG laser: The pulse duration is nanoseconds (1 nanosecond is one billionth of a second), suitable for a variety of pigment treatments.
Picosecond laser: With a pulse duration of picoseconds (1 picosecond is one trillionth of a second), it can provide shorter and more intense energy bursts, making treatment faster and more precise.
Picosecond laser: Due to the shorter pulse duration, treatment can usually be completed in fewer treatments with significant results.
Q-Switched Nd:YAG laser: More treatments may be required to achieve the same effect, and the treatment cycle is relatively long.
Research has shown that different wavelengths and power levels can be used for laser tattoo removal for different ink colors. For example:
Q-Switched Laser: Uses 532nm wavelength to effectively target red, orange and violet inks.
Picosecond laser: Using 1064nm wavelength is more suitable for removing black, blue and green inks.
In theory, Picosecond laser is a better technology than Q switch ND YAG LASER because its emission time is only 1/100 of Q switch, and it stays on the skin for a shorter time, making it more comfortable and painless. However, Q switch ND YAG LASER is also widely applicable and more cost-effective. Both methods are acceptable, and the specific choice depends on personal needs.
