Picosecond Nd Yag Laser machine for tattoo removal

The HS-298N Picosecond Nd:YAG laser system combines picosecond and nanosecond pulse modes in a single unit, designed for tattoo removal clinics, dermatology practices, and medical aesthetic facilities. With dual pulse capabilities and a fractional lens array option, the equipment supports a range of aesthetic procedures from multi-color tattoo removal to skin resurfacing, enabling commercial users to expand service offerings through one platform.

Picosecond Laser Technology of Photomechanical Effect Explained

Ultra-Short Pulse Mechanism

Picosecond lasers deliver energy pulses measured in trillionths of a second. These ultra-short pulses generate a photomechanical effect that shatters target pigment particles into dust-sized fragments, which the body's lymphatic system then eliminates. Because the pulse duration is shorter than the thermal relaxation time of surrounding tissue, the procedure targets pigment while minimizing heat transfer to adjacent skin.

Dual Pulse Mode: Picosecond and Nanosecond

The HS-298N offers both picosecond and nanosecond pulse modes. Picosecond mode (300 ps or 450 ps pulse width) is used for tattoo ink fragmentation and pigmented lesion treatment, while nanosecond mode provides an alternative option for procedures where thermal effects are desired. This dual-mode configuration allows practitioners to select the appropriate pulse duration based on treatment goals.

System Features of HS-298N Technical Capabilities

Adjustable Spot Size with Auto Energy Conversion

The system supports spot size adjustment from 2-10 mm, with automatic energy density conversion as the spot size changes. This feature helps maintain consistent fluence levels across different treatment areas, from small targeted spots to larger regions.

Seven-Joint Articulated Arm Design

Energy is delivered through a seven-joint articulated arm with 360-degree adjustability. The imported arm design provides stable beam delivery and flexible positioning, allowing operators to access treatment areas from various angles without repositioning the main unit.

Android Operating System and Interface

The HS-298N runs on an Android operating system with an ARM-A13 CPU and an 11.6-inch true color touch screen. The interface includes pre-set treatment protocols for different indications, customer database storage, and customizable application development options.

Treatment Applications of Clinical Indications

Multi-Color Tattoo Removal

The system targets tattoo ink across multiple colors, including black, dark blue, dark brown, light blue, purple, orange, light brown, and red pigments. Both 1064 nm and 532 nm wavelengths are available to address different ink colors and skin depths.

Pigmented Lesion Treatments

Indications include age spots, freckles, café au lait spots, melasma, post-inflammatory hyperpigmentation, and nevus of Ota and Ito. The picosecond pulse mechanism fragments pigment particles for gradual clearance by the body's natural processes.

Fractional Skin Resurfacing

The optional fractional lens array creates pixel-sized perforations in 7×7 and 10×10 non-ablative patterns, delivering evenly distributed energy across the fractional array. Non-sequential scanning increases the interval between adjacent spots, supporting skin heat dissipation. These micro-injury sites trigger collagen remodeling and neocollagenesis for skin rejuvenation, wrinkle reduction, and acne scar improvement.

Business Operation Features of RFID Management System

The HS-298N includes RFID/IC management control, supporting different business operation models such as membership card systems and rental arrangements. This feature helps commercial users manage equipment usage tracking, session counting, and revenue allocation across multiple operators or business models.

FAQ About Picosecond Laser Equipment Guide

How does picosecond laser differ from nanosecond laser?

Picosecond lasers deliver pulses in trillionths of a second, producing a primarily photomechanical effect that shatters pigment into smaller particles. Nanosecond lasers deliver longer pulses that rely more on photothermal effects. The HS-298N provides both modes, allowing practitioners to choose based on treatment type.

What tattoo colors can the HS-298N treat?

The system supports treatment of black, dark blue, dark brown, light blue, purple, orange, light brown, and red tattoo inks. The 1064 nm wavelength targets darker pigments, while the 532 nm wavelength addresses red, orange, and lighter pigments.

How does the fractional lens array function?

The fractional lens array divides the laser beam into multiple micro-beams, creating pixel-sized treatment zones in 7×7 or 10×10 patterns. Non-sequential scanning spaces pulses to allow heat dissipation between spots. This mode is used for skin resurfacing, collagen stimulation, and scar improvement.

What is the RFID management system used for?

The RFID/IC system tracks equipment usage and supports business operation models including membership cards and rental arrangements. It enables commercial users to monitor session counts, manage operator access, and allocate usage across different business lines or practitioners.
