The q-switched laser system is a technique for obtaining energetic short (but not ultrashort) pulses from a laser by modulating the intracavity losses and thus the Q factor of the laser resonator. The best laser for tattoo removal technique is mainly applied to generate nanosecond pulses of high energy and peak power with solid-state bulk lasers.
One laser tattoo removal machine manufacturer provides the tattoo removal machines with a cost-effective solution that yields higher returns than devices that achieve comparable results using more expensive technology.
Technology
Q-switching is a technique used in laser technology to produce short, high-intensity pulses of light. The term “Q” refers to the quality factor of the laser cavity, which is a measure of the energy stored in the cavity relative to the energy lost. By manipulating the Q factor, Q-switching allows for the rapid release of energy stored in the laser medium, resulting in a powerful pulse of light.
Mechanism of Q-Switching
Energy Storage: In a Q-switched laser, the laser medium is pumped to store energy. During this phase, the laser is in a low-Q state, meaning that the losses in the cavity are high, and the light does not build up to a significant intensity. Q-Switch Activation: Once sufficient energy is stored in the laser medium, the Q-switch is activated.
1064nm & 532nm
The 1064 nm and 532 nm wavelengths can be useful for targeting certain pigments. These two wavelengths are selectively absorbed by the melanin or tattoo pigment in the skin.
Ultra-short Pulse
The pulse is powerful enough to destroy its target, but an ultra-short pulse to not harm the skin. The short pulse produces very high peak power for optimal clinical efficiency with minimal patient pain.
When it comes to tattoo removal, the Q-switched Nd: YAG laser is widely regarded as one of the best options available. This laser type is particularly effective due to its specific wavelength and pulse characteristics, which allow for efficient targeting of tattoo pigments. Here’s an overview of why the Q-switched Nd:YAG laser is considered the best choice for tattoo removal:
Advantages of Q-Switched Nd:YAG Laser for Tattoo Removal
Wavelengths: The Q-switched Nd:YAG laser typically operates at two primary wavelengths: 1064 nm and 532 nm.
1064 nm: This wavelength is effective for darker inks (black and blue) and penetrates deeper into the skin, making it suitable for a variety of tattoo colors.
532 nm: This wavelength is more effective for lighter colors, such as red and orange, as it is better absorbed by these pigments.
High Peak Power: The Q-switching mechanism allows the Nd:YAG laser to produce very short, high-energy pulses. This high peak power is essential for breaking down tattoo ink particles into smaller fragments, which can then be absorbed and eliminated by the body’s immune system.
Minimal Damage to Surrounding Tissue: The short pulse duration minimizes thermal damage to the surrounding skin, reducing the risk of scarring and promoting faster healing.
Versatility: The Q-switched Nd:YAG laser can effectively treat a wide range of tattoo colors and types, making it a versatile option for tattoo removal.
Safety: When operated by trained professionals, Q-switched Nd:YAG lasers have a good safety profile, with a lower risk of complications compared to other methods.
