2-in-1 Advanced Laser System(LP-922) – Diode Laser (with 300W TEC Cooling) + Picosecond Laser

A professional multi-module laser device for aesthetic clinics. Diode handpiece features a dedicated 300W TEC cooling system.

Product Overview
This standing 2-in-1 laser system combines two independent functional modules—Diode Laser Module (for hair removal applications) and Picosecond Laser Module (for tattoo/pigmentation treatments). The Diode handpiece features a dedicated TEC (Thermoelectric Cooling) system with 300W cooling power, maintaining the contact tip at a controlled low temperature during operation. The Picosecond handpiece does not include active cooling and relies on standard contact application.

How It Works

Diode Laser Module (with 300W TEC Cooling) – Hair Removal Applications
The diode laser emits specific wavelength(s) of light which are preferentially absorbed by targeted chromophores in the hair follicle. The energy is converted into localized thermal effects. The integrated TEC semiconductor cooling system (300W cooling power) cools the skin contact surface before, during, and after each laser pulse. The 300W TEC system allows the contact surface to rapidly reach and maintain a preset temperature range (e.g., 5–15°C) within seconds of activation.

Picosecond Laser Module (No Cooling) – Tattoo / Pigmentation Applications
The picosecond laser delivers energy with pulse durations measured in picoseconds (10⁻¹² seconds). This ultra-short pulse width generates a photoacoustic effect, fragmenting target pigment particles. The picosecond handpiece operates without active cooling; the operator must ensure proper contact and monitor skin response.

Key Design & Technical Features

Common Applications (as intended by device design)

Diode Laser Module (with 300W cooling):

• Professional hair removal treatments on various body areas

Picosecond Laser Module (without cooling):

• Tattoo ink particle fragmentation

• Pigmented lesion treatments

Typical Operation Process

1. Client Assessment – Perform comprehensive screening (skin type, medical history, contraindications).

2. Parameter Selection – Select appropriate module, wavelength, energy, pulse duration. For diode module, also set cooling intensity (powered by 300W TEC system).

3. Preparation – Clean treatment area. Apply protective eyewear. For diode module, ensure TEC cooling is active and tip has reached preset temperature.

4. Treatment Delivery – Apply handpiece to target area. For diode, 300W TEC cooling provides contact cooling. For picosecond, no active cooling is provided.

5. Post-Treatment Care – Provide instructions and soothing skincare as needed.

Safety & Contraindications (Must Read)

✅ Operator Requirements:

• Professional use only; operator training required

• Eye protection must be worn by both operator and client

❌ Absolute Contraindications (do not treat):

• Pregnancy or breastfeeding

• Active skin infections, open wounds, eczema, dermatitis in treatment area

• Recent sun exposure (tanned skin) in treatment area

• Photosensitivity disorders or photosensitizing medications

• Malignant lesions in treatment area

• Use of isotretinoin (Accutane) within past 6 months

• Epilepsy or light-induced conditions

• Bleeding disorders or anticoagulants

• Implantable electronic devices (pacemakers, defibrillators, etc.)

• Keloid tendency

⚠️ Possible temporary effects (usually resolve within days to weeks):

• Temporary redness, swelling, tenderness

• Temporary pigmentation changes (rare)

⚠️ Important Notes:

• Perform test spot before full treatment

• 300W TEC cooling reduces but does not eliminate sensation

• Picosecond handpiece has no active cooling – monitor skin response carefully

• Proper client screening is essential
