Shengdayu 1200mJ Q-Switched Nanosecond Laser – Now Available

In the field of medical aesthetics, Q-switched nanosecond lasers have become the gold standard for treating pigmented lesions, tattoo removal, and skin rejuvenation – thanks to their high peak power and ultra-short pulse duration. Shengdayu is proud to introduce its 1200mJ Q-Switched Nanosecond OEM Medical Aesthetic Laser, delivering 1200mJ single-pulse energy, a flat-top beam profile, and exceptional energy stability. This high-performance, highly reliable laser engine is purpose-built for medical aesthetic equipment manufacturers seeking uncompromising quality and consistency.

Core Performance: 1200mJ High-Energy Output with Uniform Flat-Top Beam Coverage

Laser output energy and beam quality are the two most critical factors in determining treatment uniformity and safety. This laser delivers ≥1200mJ at 1064nm and ≥550mJ at 532nm, combined with a flat-top spatial beam profile and an ~10mm spot size – enabling broad, uniform coverage across the entire treatment area.

● 1200mJ high energy – Delivers ample peak power to effectively target dermal pigment particles through efficient photoacoustic disruption, while reducing the number of treatment sessions required and enhancing the overall patient experience.

● Flat-top spatial beam profile – Unlike Gaussian beams, which concentrate energy at the center and taper off at the edges, the flat-top profile delivers uniform energy density across the entire spot. This ensures that every area of the skin receives the same energy dose – eliminating the risk of over-treatment at the center and under-treatment at the margins. This is particularly critical for large-spot treatments where uniformity is paramount.

● ~10mm large spot size – Combined with the flat-top profile, the large spot size covers more ground with each pulse, significantly improving treatment efficiency without compromising safety.

Dual-Wavelength Output: Seamless 1064nm / 532nm Switching for Versatile Indications

The laser supports both 1064nm and 532nm wavelengths, allowing clinicians to select the optimal wavelength for different treatment depths – from deep dermal pigmentation to superficial epidermal lesions.

Superior Energy Stability – Consistent Results, Pulse After Pulse

Energy stability is one of the most critical quality indicators for medical aesthetic lasers. This system achieves ≤2% energy stability at 1064nm and ≤3% at 532nm, ensuring that every pulse delivers a highly consistent energy output. This minimizes the risk of under- or over-treatment due to energy fluctuations, enhancing both safety and treatment predictability.

Nanosecond Pulse Width – High Peak Power for Optimal Photoacoustic Effect

With a pulse width of 6-8ns (FWHM @1064nm), the short-pulse design generates exceptionally high peak power, effectively fragmenting pigment particles in a fraction of a millisecond while keeping thermal damage to surrounding healthy tissue to an absolute minimum – true to the principle of selective photothermolysis.

Exceptional Beam Quality – Seamless Integration with Existing Optical Paths

● Beam divergence: 4 mrad – The low divergence angle ensures excellent focusing characteristics even over long transmission distances, making it fully compatible with a wide range of articulated arms and optical delivery systems.

● Flat-top uniform beam profile – Smooth energy distribution eliminates localized energy spikes, significantly reducing the risk of adverse skin reactions.

Flexible Repetition Rate & Wide Operating Conditions

● Repetition rate: 1–10 Hz adjustable – Accommodates various treatment protocols, giving clinicians the flexibility to select the optimal pulse frequency based on indication and skin type.

● Operating temperature: 20–35°C; humidity: <60% – Designed to perform reliably in standard clinical environments with minimal environmental control requirements.
