Shandong Haucore Optoelectronics Co., Ltd. introduces the HGLD‑792‑COS‑D‑10WB semiconductor laser within its COS series. Delivering an output power of 10 W at a central wavelength of 792 nm, this device adopts gold‑tin bonding COS packaging. Featuring high reliability and long service life, it serves as a preferred pump source for solid‑state lasers and is widely deployed in industrial processing, laser display, medical & aesthetic treatment, scientific research and other fields.
Key Product Features
The HGLD‑792‑COS‑D‑10WB is a high‑power near‑infrared laser die in COS package. The gold‑tin solder packaging structure reduces thermal resistance and improves thermal‑fatigue resistance to sustain continuous high‑power operation. Leveraging the company’s full‑chain in‑house capabilities covering epitaxy, die fabrication and device packaging, the laser offers outstanding stability and long operational lifetime for prolonged continuous‑run scenarios in industrial and medical equipment.
With a central wavelength of 792 nm and a wavelength thermal drift coefficient of 0.3 nm/℃, the unit delivers stable spectral output and is well‑suited for pumping thulium‑doped solid‑state crystals. Its typical electro‑optical conversion efficiency reaches 57 %, lowering heat dissipation burden and power‑supply requirements for end‑user systems. The beam performance is optimized: the fast‑axis divergence angle (95 % power) is less than 50°, while the slow‑axis divergence angle (95 % power) is below 10°, simplifying optical coupling system design.
The recommended operating ambient temperature ranges from 10 ℃ to 35 ℃, and the storage temperature spans ‑40 ℃ to 75 ℃, enabling integration into diverse equipment solutions.
