Picolaser Dark Spot Removing Machine

Q-Switched Nd:YAG Laser Therapy Systems

ExQ-Laser™ is safety and reliable with excellent performance, has successively achieved Certificates from CFDA , Medical CE and Australian TGA. Its unique designs also earn multiple global patents.

ExQ-Laser™ is newly released

Q-Switched Nd:YAG laser therapy system. The system has an optimal clinical treatment effect with following parameter designs: dual-wavelength switching of 1064nm & 532nm, pulse width short to 5ns and Energy output up to 1000mJ.

Introduction

ExQ-Laser™ integrated with real-time energy monitor, energy auto-changing by adjustable handpiece, water filtration system, sufficiently guarantee the safety and efficiency during using. New UI designs focuse on user experience, make the operation simpler and more convenient.

Principle of Treatment

Treatment principle for pigmented dermatosis of Q-Switched Nd:YAG Laser Therapy system lies in selective photothermolysis with melanin as the chromophore.

Q-Switched Nd:YAG has higher Peak power and nanoseconds-level pulse width. Melanin in melanophore and cuticle formed cells have a short hot relaxation time. It could immediately make small selectively energy absorbed granules (tattoo pigment and melanin) blast without injuring surrounded normal tissues. The blasted pigment granules will be excreted from body through circulatory system.

Depth of penetration in the Skin

1.Melanin granules in skin

2.Melanin granules’ absorbing laser energy

3.Instantaneously blasted of melanin granules

Clinical Indications:

1064nm nevus of ota, black and blue tattoo

Epiderma

532nm freckles, café-au-lait spots, red tattoo

Derma

Advanced Tattoo Removal

Hypoderma

1064nm targets darkink 532nm targets red

Absorption Spectrum for Melanin and Hemoglobin

Prominent Advantages

Two stages Nd:YAG laser system with electro-optic Q-Switched technology, which output higher energy. The designs adopt cavity optimized schedule, make the pulse width as short as 5ns, get doubled output power density under the same energy.

Integrated laser energy monitor system inside, set warning signal when energy deviation over threshold, all to ensure treatment effectiveness and safety.
