Laser automatic constant-temperature heating system

As a professional ultraviolet‑laser solution provider, Precilasers has launched its 266 nm narrow‑linewidth industrial laser, delivering reliable single‑frequency output for high‑precision interference lithography, semiconductor inspection and precision metrology applications.

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.

Driven by fast‑growing demands of 3D perception, biometric authentication and machine‑vision industries, near‑infrared imaging optics have become a vital hardware component for intelligent sensing systems.

The ElFys PD25s series photodetectors adopt ElFys‑patented Black Silicon Induced Junction technology, delivering excellent spectral response spanning deep‑ultraviolet, visible and near‑infrared bands for diverse high‑precision photometry applications. Sub‑variants including H, M, HG and MG are optimised for low‑capacitance, low‑dark‑current and high‑reverse‑bias guard‑ring operations respectively. Multiple packaging configurations are available to satisfy various system‑design requirements.
