Engineered for extreme reliability, clinical efficacy, and seamless integration into professional aesthetic handpieces.
Modern laser hair removal requires a fine balance between high melanin absorption, deep optical penetration depth, and excellent epidermal safety. Single wavelength platforms—most commonly historical 808nm diode systems—cannot address all phototypes and hair variations dynamically. Xi'an Prima Beauty Equipment Co., Ltd. has engineered its high-power semiconductor arrays to combine 755nm, 808nm, and 1064nm in a single, co-axial diode stack output.
By blending these wavelengths in optimized proportions, clinics can deliver energy that targets three distinct anatomical structures within the hair follicle simultaneously:
With over 10 years of experience in manufacturing medical and aesthetic laser equipment, we have established ourselves as a premier aesthetic technology partner globally. Our operations integrate vertical chip packaging, optoelectronic assembly, precise mechanical design, and comprehensive sales distribution under one ISO 13485 compliant facility.
By controlling the complete lifecycle of our laser diode stacks—from the raw GaAs semiconductor arrays to the micro-channel coolers (MCC)—we ensure that each handpiece component offers superior thermal efficiency and long lifetimes. Our high-power solutions, ranging from 300W to 4800W, power both state-of-the-art complete platforms (CO2 fractional, Pico, IPL, Diode hair removal systems) and specialized aftermarket replacement components.
Our head office integrates diode laser physics and solid-state laser R&D with professional beauty equipment sales. By developing and manufacturing laser chips alongside mechanical shells and control circuitry, our teams provide a level of application knowledge that standard OEM assembly houses cannot replicate.
Primary Products: Diode Hair Removal Laser Systems, CO2 Fractional Lasers, Picosecond Q-Switched Systems, IPL Platforms, and high-performance replacement stacks optimized for Alma and other major western brands.
Our scientific approach to diode manufacturing has earned the trust of medical device brands, aesthetic service centers, and aesthetic distributors worldwide.
Discover why leading distributors and clinics trust our medical-grade diode stack assemblies.
We combine high-end semiconductor packaging with Fast Axis Collimation (FAC) lenses. This optical technique squeezes the divergent light beams from the laser bars into a highly concentrated, parallel output, improving energy density and depth of target penetration.
Every single diode stack undergoes continuous burn-in testing and thermal profiling for 72+ hours before assembly. Spectrum, output power, polarization, and spot profiles are measured and documented to guarantee performance stability.
We provide tailormade engineering designs for direct physical integration. Whether you are building a new aesthetic system or rebuilding a worn-out premium handpiece (such as MCC modules from famous European/American makers), our customization matches the structural envelope and electrical footprints perfectly.
Analyzing the shift from manual mechanical assemblies to high-output semiconductor integrations.
The global aesthetic market is experiencing high density saturation of hair removal platforms. However, the weakest link in these platforms remains the handpiece. Thermal-stress, high current densities, and minor coolant contamination lead to micro-crack propagation and bar burnout. Direct manufacturers and clinics face high replacement costs. This has driven a major shift toward independent global sourcing for premium laser stack assemblies. Buyers look for long-life micro-channel stacks that can fit existing systems, saving up to 70% in maintenance expenditures compared to purchasing complete OEM handpieces.
Historically, soft solder (Indium) was used for stacking diode bars due to its lower cost and ease of assembly. Under heavy continuous operation, thermal migration causes Indium oxidation, whisker formation, and rapid laser degradation. Our facility uses hard solder—Gold-Tin (AuSn) eutectics—which offers exceptional thermal conductivity, a melting point exceeding 280°C, and complete immunity to electromigration under high current pulses. This ensures our stacks maintain stable power outputs even over millions of pulses.
To achieve high efficacy while maintaining short, safe pulse widths (under 20ms to protect the surrounding skin), high optical peak power is essential. By scaling up the stack configurations from standard 600W systems to 2400W, 3600W, and even 4800W multi-bar arrays, professional systems can achieve maximum target tissue temperature in milliseconds. This results in painless treatments and removes even stubborn, light-colored hair with fewer sessions.
Our manufacturing processes comply with strict global safety protocols. Each product line undergoes extensive quality assurance checks.
Addressing the core technical considerations for engineers, distributors, and laser repair specialists.
From single-bar arrays to double-row stacks, we manufacture high-reliability replacements and custom designs.
