HQE Series Diode‑Pumped Solid‑State Long‑Pulse Laser

The HQE Series Diode-Pumped Solid-State (DPSS) Long-Pulse Laser is a high-performance, precision laser source engineered specifically for advanced medical and aesthetic applications. Operating at a wavelength of 2940nm, this laser matches a primary absorption peak of water, making it exceptionally effective for precise tissue interaction with minimal thermal damage to surrounding areas.

Designed for seamless integration into OEM medical systems, the HQE series delivers stable, reliable energy output tailored for demanding clinical environments. Its robust solid-state architecture ensures long-term operational reliability, making it the ideal laser source for manufacturers developing next-generation dental veneer and preparation equipment, as well as high-precision dermatology and skin-resurfacing devices.

FAQ
Q: What medical and aesthetic applications is the HQE Series 2940nm laser designed for?
A: The HQE series is primarily engineered as a core laser source for medical equipment, specifically optimized for dental applications (such as dental veneer preparation and hard-tissue treatments) as well as dermatology devices (such as skin resurfacing and ablation).

Q: Why is the 2940nm wavelength ideal for dental and dermatology devices?
A: The 2940nm wavelength exhibits an extremely high absorption coefficient in water—the primary chromophore in biological tissues. This allows for precise, highly efficient ablation and cutting with minimal thermal penetration, resulting in safer procedures and faster patient recovery times.
