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.
The MSL‑T series water‑cooled continuous‑wave single‑longitudinal‑mode lasers from Changchun New Industries Optoelectronics (CNI) deliver key research wavelengths including 369 nm, 405 nm and 770 nm.
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.
