The main function of EDFA in the optical fiber communication system is to extend the relay distance. When it is combined with wavelength division multiplexing technology and optical arc technology, it can realize ultra-large capacity and ultra-long distance transmission.

VBG technology (Volume Bragg Grating) is an optical filtering and wavelength control technology based on the three-dimensional periodic refractive index modulation of photosensitive materials. Its core applications include laser wavelength locking, linewidth narrowing, and beam shaping, and it is widely used in high-power lasers, pump sources (such as 976nm/980nm laser diodes), and fiber optic communications.

Recently, Shenzhen Box Optronics Technology Co., Ltd. has completed the production and final testing of a batch of BSLD-840-7SM-FA-M Broadband Light Source Modules, which have smoothly entered the shipment process to provide stable and reliable light source solutions for customers' applications in optical communication, sensing, and other fields.

Erbium-doped mode-locked fiber laser is a laser that uses erbium-doped optical fiber as an active medium. Erbium-doped elements can absorb light energy within a specific wavelength range and emit laser photons of a specific wavelength. Mode-locked fiber laser is a laser that can produce extremely short pulses and is often used in scientific research, communication technology, and material processing.

The traditional laser uses the thermal accumulation of laser energy to melt and even volatilize the material in the active area. In the process, a large number of chips, micro-cracks and other processing defects will be generated, and the longer the laser lasts, the greater the damage to the material. The ultra-short pulse laser has an ultra-short interaction time with the material, and the single-pulse energy is super strong enough to ionize any material, realize non-hot-melt cold processing, and obtain the ultra-fine, low-damage processing advantages incomparable with long-pulse laser. At the same time, for the selection of materials, ultrafast lasers have wider applicability, which can be applied to metals, TBC coatings, composite materials, etc.
