High-power density laser emission cores engineered for aesthetic hair removal platforms and handpiece refurbishment/repair services.
Welcome to Xi’an Prima Beauty Equipment Co., Ltd., your trusted global partner in high-intensity optoelectronic technologies and medical-grade beauty equipment. With over 10 years of expertise in aesthetic laser manufacturing, solid-state lasers, and micro-channel bar stacks, we lead the industry through continuous research and clinical innovation.
Prima Beauty Laser is widely recognized for delivering high-power diode hair removal lasers, fractional CO2 platforms, Picosecond systems, high-energy IPL modules, and skin management systems. Our head office seamlessly integrates raw laser chip encapsulation, diode stack vertical integration, complete handle packaging, and final medical aesthetic machine manufacturing under one QA/QC matrix.
Providing industrial-grade stability, customized optics integration, and complete lifecycle technical support.
As a leading Chinese supplier of mid-to-high-end optoelectronic parts, we integrate chip R&D, advanced eutectic soldering (AuSn), micro-channel cooling (MCC), and professional beam collimation (FAC) inside our cleanrooms, ensuring top-tier optical efficiency and stability.
Every vertical diode stack and module undergoes rigorous 72-hour aging tests and peak power density profiling. Our optical chips are protected against thermal stress and micro-channel clogging, ensuring safe operation up to tens of millions of pulses.
We offer direct mechanical, electrical, and optical replacement stacks for major international aesthetic brands (e.g., Alma Soprano handle repair). Tailored wavelength configurations, current-voltage customization, and personalized housing logos are available.
A deep technical dive into market demands, thermal fluid dynamics, and optical structures driving modern aesthetic platforms.
In the global medical and spa industries, diode laser hair removal systems representing 808nm, 755nm, and 1064nm wavelengths are the gold standard for clinical hair removal. However, the operational lifespan of the laser emitter stack is heavily constrained by thermoelectric variables, duty cycles, and water purity conditions.
Historically, clinic owners and distributors faced high costs replacing entire handpieces from original western brands. Today, the global demand has pivoted toward component-level replacement stacks and OEM modules. Direct wholesale manufacturing enables distributors to offer high-quality stack rebuilds at a fraction of original costs, matching or exceeding original equipment performance.
The core failure mode of diode laser bars is thermal stress leading to degradation at the junction interface. Under continuous pulsing (CW/quasi-CW modes), indium solder is prone to "indium migration" and thermal fatigue at high temperatures.
Xi'an Prima Beauty implements Gold-Tin (AuSn) hard solder technology. AuSn maintains mechanical stability up to 280°C, preventing solder creeping or voids under heavy usage. This engineering shift improves thermal management, ensuring the diode laser stack handles power densities up to 4800W without wavelength shifting or optical degradation.
Operating vertical diode laser stacks requires efficient heat dissipation. Heat flux at the diode junction can exceed kilowatts per square centimeter. Manufacturers use two primary design approaches: Micro-Channel Coolers (MCC) and Macro-Channel Coolers (MCM).
| Performance Metric | Micro-Channel Cooler (MCC) Stack | Macro-Channel Cooler (MCM) / HPL Module |
|---|---|---|
| Thermal Resistance | Extremely Low (~0.1 - 0.2 K/W per bar) | Moderate (~0.4 - 0.6 K/W per stack) |
| Water Quality Requirements | Strict (Deionized water, conductivity < 5 μS/cm, 5μm filter) | Standard (Purified water, less sensitive to scaling) |
| Power Density per Bar | High (Up to 100W - 200W per bar) | Standard (Up to 40W - 80W per bar) |
| Ideal Applications | Alma Soprano handle repair, High-end clinical devices | Industrial pumps, budget-friendly salon equipment |
| Eutectic Bonding | AuSn (Gold-Tin) hard solder required | Indium or AuSn solder options |
A raw laser bar has a highly divergent fast axis (typically 35° to 40°). Without beam conditioning, the energy scatters rapidly, lowering penetration depth in tissue and causing thermal damage to the epidermis.
To achieve high energy density (fluence) and target the hair follicle root, we integrate Fast Axis Collimation (FAC) micro-lenses directly on each bar. The FAC lens collimates the divergence angle to under 2°, allowing the output energy to remain focused through sapphire light guides. This maximizes deep-dermal penetration and clinical safety.
Different skin and hair types require target absorption profiles across the melanin spectrum. Combining multiple wavelengths into a single stack optimizes treatments:
The future of high-power semiconductor lasers and our structural engineering roadmap.
Optimizing GaAs wafer structures to achieve conversion efficiencies over 65%, reducing waste heat at the source.
Transitioning all MCM and vertical modules to automated gold-tin eutectic bonding to prevent thermal fatigue.
Standardizing Fast Axis (FAC) and Slow Axis (SAC) collimation to deliver highly uniform square spots without hotspots.
Developing modules with embedded temperature and current sensors to provide real-time feedback to the host controller.
High-power modular assemblies optimized for industrial pumping, medical research, and advanced aesthetic systems.
Technical specifications and commercial logistics answered by our engineering team.
Our micro-channel cooling (MCC) stacks, assembled using AuSn hard solder, are rated for 30 million to 50 million pulses under optimal operating conditions. Maintaining pure deionized water circulation and keeping temperatures below 25°C prevents premature degradation.
Yes. We specialize in retrofitting and repair services for third-party handpieces. We manufacture replacement stacks designed to match the electrical configurations, physical positioning, and optical properties of systems like the Alma Soprano Ice/Platinum series.
Micro-channel stacks require high-quality deionized water to prevent scale build-up in the micro-channels. Flow rates must be maintained at 2.0 to 3.5 L/min with system pressures between 0.3 and 0.5 MPa. Using filters down to 5 microns is highly recommended.
We support customized vertical configurations combining 755nm, 808nm, 940nm, and 1064nm wavelengths in a single array. Clients can specify the bar configuration (e.g., repeating 755/808/1064 patterns) to target different melanin absorption levels.
Yes. Our R&D team can customize stack dimensions, mount spacing, pinouts, and target housing footprints to ensure drop-in compatibility with your existing handpiece designs or shell mechanics.
All chip integration, eutectic mounting, wire bonding, and alignment processes are conducted in ISO Class 10,000 cleanrooms. Stacks undergo continuous load testing, spatial profiling, and spectral analysis prior to packaging and shipment.
