High-performance OEM laser diode solutions optimized for replacement handles, handpiece repairs, and advanced laser systems integration.
Welcome to Xi’an Prima Beauty Equipment Co., Ltd., your trusted partner in the global domain of high-quality beauty equipment. With over 10 years of experience in manufacturing laser beauty equipment, we take pride in being a leading beauty equipment factory, specializing in the production, research, and development of cutting-edge optical beauty technology.
Prima Beauty Laser is recognized globally for providing a wide range of high-quality beauty equipment, including diode hair removal laser machines, CO2 fractional laser machines, Pico Q-switched laser machines, IPL laser machines, and skin management systems. Integrating vertical supply chains, our headquarters leads research in diode laser chips, high-power solid-state lasers, and robust handle repair manufacturing ecosystems.
Deciphering the optoelectronic core of high-density diode laser architectures, including multi-wavelength chips and micro-channel thermal engineering.
The efficiency of a diode laser for hair removal relies entirely on its semiconductor array structure. Historically, manufacturers focused solely on single 808nm wavelengths. However, clinical demands have driven a technology roadmap toward triple and quadruple-wavelength integration, high-density bar packing, and advanced micro-channel cooling structures.
| Wavelength | Target Chromophore | Skin & Hair Type Target | Optical Penetration Depth | Core Value Proposition |
|---|---|---|---|---|
| 755nm | Melanin (High Absorption) | Light skins (Fitzpatrick I-III), fine & light hair | Superficial (Dermis-Epidermis junction) | Excellent for residual and light-colored hair removal sessions. |
| 808nm / 810nm | Melanin (Moderate Absorption) | All skin types (Fitzpatrick I-VI), standard hair | Medium (Middle Dermis layer) | The golden standard for rapid, high-frequency treatments. |
| 940nm | Oxyhemoglobin (Coagulation) | Darker skins, vascular-fed hair follicles | Deep Dermis | Targets the micro-vessels feeding the hair bulb, enhancing efficacy. |
| 1064nm | Water & Hemoglobin (Low Melanin) | Dark skin (Fitzpatrick V-VI), deep hair follicles | Deepest (Subcutaneous fat layer) | Maximum safety for dark-skinned patients, avoiding epidermal burn risks. |
To scale up to output levels of 2400W and 4800W, our engineering leverages Gold-Tin (AuSn) Eutectic Solder. Unlike legacy Indium soldering, AuSn prevents electro-migration and oxidation, guaranteeing over 50 million pulses without power decay. Additionally, integrating Fast Axis Collimator (FAC) Lenses compresses divergence angles down to <2 degrees, ensuring concentrated light delivery and optimal fluence levels.
From semiconductor packaging to complete aesthetic workstation integration, we guarantee high-efficiency operations.
As a leading Chinese supplier, we integrate the full chain of laser chip research, semiconductor packaging, diode stack manufacturing, and final system integration under one roof. This guarantees premium quality control from the raw wafer stage to the finished handpiece.
Every single optical module undergoes rigorous long-duration testing (up to 72 hours of continuous duty cycle burn-in testing) to verify energy density stability and prevent premature bar burn-outs before shipping.
We provide full-spectrum OEM and ODM customization, supporting private label chassis designs, customized wavelength distributions, and professional handle repair/re-stacking services for Alma, Lumenis, and Cynosure handles.
The manufacturing cluster in Xi'an represents China's leading hub for optoelectronic research. Xi'an Prima Beauty Equipment Co., Ltd. capitalizes on this geographic advantage to construct a state-of-the-art cleanroom environment (Class 10k/100 dust-free standards) where our diode laser bars are mounted under sterile atmospheres.
By optimizing automated production processes, we maintain absolute consistency across our vertical stacks. Our automated bar placement, high-vacuum eutectic bonding ovens, and computerized optical spectrum testing significantly reduce manual labor variances. This guarantees high precision, prevents thermal hot-spots on the diode surfaces, and ensures competitive wholesale pricing.
Tailored business solutions for medical spa networks, aesthetic device distributors, and service centers looking to streamline operations.
Accelerate your speed-to-market. By utilizing our CE-certified diode stacks and power modules, you can assemble your branded systems with confidence. We offer customizable chassis, software interfaces, localized logos, and technical engineering support to help you achieve regulatory approvals in your domestic markets.
Reduce your operation costs. Instead of purchasing complete replacement handpieces, repair centers can source our OEM laser diode stacks (such as the 800W, 1200W, or 2400W stacks) to rebuild Alma Soprano Ice, Alma Titanium, or Lumenis LightSheer handles. Save up to 70% in capital costs for your clients.
Certified compliance with international aesthetic safety guidelines and medical production standards.
Aesthetic medical regulations vary significantly across jurisdictions, including FDA pathways in the USA, MDR regulations in Europe, and NMPA certifications in China. Sourcing components with proper certification is critical to operational success.
Our laser diode modules and complete systems are manufactured in compliance with ISO13485 medical quality management guidelines. We offer detailed technical files, electrical schematics, optical testing reports, and skin test validation data to support your local registration requirements.
Technical and procurement answers directly from our senior optical engineering and design teams.
Micro-Channel Coolers (MCC) feature sub-millimeter water channels directly underneath the laser bars, which provides superior heat dissipation efficiency and allows the diode to run at higher power levels with longer continuous pulse frequencies. However, they require high-quality deionized water. Macro-Channel Coolers use larger cooling channels, which are less prone to clogging and require lower water filtration quality, but have lower cooling rates and are generally suited for lower-wattage systems.
Indium solder is susceptible to thermal creep and electro-migration under high temperatures and current densities, which can lead to progressive diode decay and catastrophic optical damage (COD). Gold-Tin (AuSn) solder offers higher melting points, superior mechanical strength, and excellent thermal matching to the semiconductor chip, helping prevent bar shifting and ensuring stable operation over tens of millions of shots.
Yes. We offer standard-dimension replacement diode stacks specifically engineered for Alma Soprano ICE, Alma Titanium, and various other popular aesthetic devices. Our engineers reconstruct legacy micro-channel designs using premium chips, providing a cost-effective alternative to buying a new handpiece.
Selecting the optimal wavelength depends on the predominant skin types in your target region. For markets with diverse populations, a triple-wavelength (755/808/1064nm) or quadruple-wavelength (755/808/940/1064nm) configuration is recommended to safely and effectively treat all skin tones, from light-skinned patients to dark-skinned patients, in a single system.
High-power arrays, multi-bar modules, and custom wavelength vertical stacks designed for industrial, scientific, and aesthetic applications.
