HQF Series Lamp-Pumped Long Pulse 2940nm Er:YAG Laser

RealShock® HQF Series Lamp-Pumped Long-Pulse 2940nm Er:YAG Laser Product Introduction
RealLight Technology launches the RealShock® HQF Series Lamp-Pumped Long-Pulse 2940nm Er:YAG Laser, specially developed for dental clinical and skin repair medical equipment. The integrated system consists of a laser emission module and built-in real-time energy detection unit, outputting core mid-infrared wavelength at 2940 nm. This wavelength matches the strongest absorption peaks of water molecules and dental hydroxyapatite, delivering precise tissue ablation with minimal thermal damage. Combined with ultra-high pulse energy, stable output and uniform beam profile, it acts as the core medical light source for implant dentistry, periodontal treatment and skin resurfacing devices. Optional supporting accessories include delivery fiber, medical articulated arm, touch control screen, dedicated power supply and recirculating water chiller, enabling easy system integration for medical equipment manufacturers.

1. Overall Structure & Safety-Oriented Integrated Design
The HQF 2940nm Er:YAG laser adopts a mature lamp-pumped amplification optical path with modular separation of laser main body and energy detection unit, featuring compact layout for embedding into dental chairs and skin laser treatment instruments. Two standard built-in safety components are equipped: built-in energy detector and integrated safety optical shutter to guarantee standardized clinical treatment.
The built-in energy detector captures real-time pulse energy data and transmits feedback to the matched control screen, allowing clinicians to calibrate and lock treatment parameters on-site for consistent therapeutic effects across all operations; it also supports factory calibration and clinical training experiments. The integrated optical shutter instantly cuts off laser emission to avoid accidental light exposure and greatly improve clinical safety.
Two output modes are available for selection: hollow-core delivery fiber or medical articulated arm, suitable for minimally invasive dental handpiece operation and large-area fractional skin resurfacing respectively. The matched standard water cooling system stabilizes optical path temperature during long-duration continuous surgery and prevents energy attenuation. The power supply supports wide-range 110V/220V ±10% AC input compatible with power grids worldwide.

2. Core Performance Advantages
2.1 Gold-Standard 2940nm Medical Wavelength for Minimally Invasive Minimal Thermal Damage
The 2940 nm mid-infrared laser exhibits extremely high absorption by tissue water and dental hydroxyapatite, with far higher absorption coefficient than CO₂ and Nd:YAG lasers. Laser energy only acts on superficial target tissues with narrow thermal diffusion, eliminating carbonization during operation, reducing postoperative swelling and shortening recovery time. In dental treatment, it cuts both hard dental bone and soft gingival tissue simultaneously; for dermatology, it precisely vaporizes epidermal lesions while protecting the dermis to lower risks of pigmentation and scar hyperplasia.

2.2 Ultra-High Single Pulse Energy with Wide Adjustable Energy Range
Pulse energy varies with repetition rates: maximum 2000 mJ at 10 Hz and stable 500 mJ at 20 Hz, with total average power of 20 W for flexible switching between high and low energy modes. Low-energy settings apply to periodontal debridement and skin rejuvenation; ultra-high energy modes meet demands of implant bone shaping and severe scar resurfacing, covering full-spectrum clinical treatments. The 300~500 μs long pulse width enables gentle and controllable ablation with minimal intraoperative bleeding and clear surgical vision.

2.3 Stable Output for Repeatable Clinical Results
Laser energy instability and energy repeatability are both better than ±20%, delivering consistent energy output during long surgeries to ensure standardized treatment results regardless of operators or multiple treatment sessions. The multi-mode beam features flat energy distribution without local energy hotspots to avoid excessive tissue burns. Equipped with a 532 nm green aiming beam over 2 mW, it enables precise pre-operation targeting to boost surgical accuracy.

2.4 Loose Environmental Requirements for Universal Medical Use
The laser operates stably under mild environmental conditions: ambient temperature 10°C~30°C, non-condensing relative humidity 10%~73%, atmospheric pressure 86kPa~106kPa. No dedicated constant temperature & humidity room is required for ordinary dental clinics and aesthetic salons, cutting overall equipment deployment costs.

3. Full Technical Parameter Description
The HQF 2940nm Er:YAG laser features fixed output wavelength at 2940 nm. Two pulse energy grades are provided: max 2000 mJ at 10 Hz and 500 mJ at 20 Hz, with total average power of 20 W and adjustable pulse width ranging from 300 to 500 μs. It outputs multi-mode beams and supports two delivery options: optical fiber or articulated arm. Both laser energy instability and repeatability indicators exceed ±20%. A 532±20 nm green aiming beam with output power over 2 mW is integrated.
Operating environment specifications: temperature 10°C~30°C, non-condensing relative humidity 10%~73%, applicable atmospheric pressure 86kPa~106kPa. Power supply accepts 110V/220V ±10% AC, 50/60Hz global power grids. Standard built-in energy detector and safety shutter are included; optional accessories such as delivery fiber, articulated arm, control panel, power supply and water chiller can be configured on demand.

4. Key Clinical Application Fields
4.1 Periodontal Therapy
Applied to periodontal pocket debridement, tartar removal, gingivotomy and periodontal disinfection. The 2940 nm laser efficiently eliminates plaque biofilm inside pockets, minimally processes inflammatory soft tissue, lowers intraoperative pain and accelerates gingival healing while reducing bleeding and irritation caused by traditional mechanical instruments.

4.2 Implant Treatment
Used for implant site preparation, peri-implantitis debridement and pathological alveolar bone reshaping. The laser precisely removes infected granulation tissue and lesioned bone without damaging titanium implant surfaces, effectively suppressing inflammation and promoting osseointegration to reduce implant failure risks. It enables minimally invasive bone cutting without traditional bone drills for improved surgical comfort.

4.3 Skin Resurfacing & Aesthetic Medicine
Suitable for fractional rejuvenation, wrinkle reduction, acne scar repair, superficial pigment lesion removal and photoaging treatment. It accurately vaporizes aged epidermis and stimulates dermal collagen regeneration with ultra-small thermal damage zones, featuring short postoperative recovery time and low risks of pigment rebound and hypertrophic scars, ideal for minimally invasive anti-aging procedures for all skin types.

5. Product Summary
Built on mature lamp-pumped amplification optical path, the RealShock® HQF Series Lamp-Pumped Long-Pulse 2940nm Er:YAG medical laser adopts the clinically recognized 2940 nm absorption wavelength, integrating five core strengths: up to 2000 mJ ultra-high pulse energy, built-in energy detector & safety optical shutter, minimally invasive low thermal damage, stable output and dual delivery transmission options. The adjustable high/low energy modes fully cover periodontal dentistry, implant surgery and skin resurfacing scenarios. Standard modular design facilitates rapid integration for medical equipment manufacturers, with complete supporting accessories and strong environmental adaptability. As a high-performance domestic mid-infrared erbium laser source, it serves as a cost-effective alternative to imported Er:YAG lasers for dental equipment manufacturers, aesthetic instrument enterprises, dental hospitals and aesthetic clinics.
