How Q-Switched Nd:YAG Laser Works?

High-Energy, Short Pulses

Delivers extremely short yet intense pulses (6-10 nanoseconds) with high peak power.

Ensures precise fragmentation of pigment or ink particles without excessive heat buildup.

Selective Wavelength Absorption

1064nm wavelength: Penetrates deep into the skin, effectively treating melasma, freckles, age spots, and dark-colored tattoos (black/blue/gray).

532nm wavelength: Targets more superficial pigmentation, ideal for red, pink, orange tattoo ink, and sun-induced pigmentation.

Photoacoustic Effect – Breaking Down Pigment

The laser pulses generate a photoacoustic effect, shattering pigment particles into microscopic fragments.

These micro-fragments are naturally eliminated by the lymphatic system, leading to progressive fading of pigment or tattoos over multiple sessions.

Minimal Damage & Fast Healing

The laser energy is absorbed only by the targeted pigment, leaving surrounding tissues unaffected.

This results in faster healing with minimal risk of scarring, burns, or post-inflammatory hyperpigmentation.

Applications of Q-Switched Nd:YAG Laser

Collimating lens

The collimating Lens uses convex lenses or other method to convert divergent incident light into parallel beams of energy to the target tissue with minimal dispersion,regardless of distance form the skin.

Array lens(532nm+1064nm)

Array lens makes energy more concentrated,the pigment is shattered and metabolism more easily,besides,it will stimulate collagen to regenerate,accordingly to repair scars and reduce wrinkles.

Fractional Lens array(DOE 6×6mm)

The fractional lens array creates pixel-sized perforations in a 5×5 or 6×6 non-ablative pattern,evenly distributing energy across the treated area.It can also perform non-sequential scanning,which increases the interval between adjacent pulses and improves heat dissipation.This process stimulates collagen production,triggers neocollagenesis,and rejuvenates the target tissue.

Long pulse Hair removal

Due to the weak absorption of water,hemoglobin,and melanin at 1064nm,the laser can penetrate the skin and reach subcutaneous tissue(with a depth of up to 3mm).This makes it ideal for hair removal on darker skin tones.The long pulse width allows for slow heating of the hair follicles,preventing sudden temperature increases that could damage the epidermis
