Dielectric high-reflection mirror
A dielectric high-reflection mirror is an optical component with a multilayer dielectric coating, achieving high reflectivity in a specific wavelength band through thin-film interference, thereby minimizing energy loss and thermal effects. Its reflection characteristics depend on the coating design, and it is suitable for laser resonant cavities, beam deflection systems, and precision optical interferometers. Compared with metal mirrors, dielectric high-reflection mirrors have higher reflectivity and lower absorption, and possess strong laser damage resistance, and are widely used in the construction of optical paths for high-power laser systems and spectral equipment.

Fiber lasers and fiber amplification systems require excitation sources with stable wavelength, narrow spectral linewidth and consistent output power.
BEIJING JIEPU TREND supplies YAG+Er:YAG+YAG bonded composite slab laser crystals for high‑power solid‑state laser systems. The monolithic slab consists of two undoped YAG end‑cap layers and a central Er‑doped YAG gain segment. The overall dimension is 9 mm×9 mm×9 mm.

Ytterbium‑doped fiber serves as the core energy‑conversion component inside a fiber laser. Pump light emitted by laser diodes is coupled into the gain fiber, and energy is transferred to signal laser beams via ytterbium ion energy‑level transition for power amplification. Two dominant pump wavelengths, 915 nm and 976 nm, have been widely adopted over decades. With the rapid progress of pump chip and wavelength‑locking technology, 976 nm edge‑emitting laser (EEL) pumps have gradually surpassed the 915 nm route and become the new industry mainstream. Shenzhen Lemon Photonics Technology Co., Ltd keeps developing high‑performance pump chips for fiber laser manufacturers.
