1060nm Ase Broadband Light Source Manufacturers

Compared with discrete optical fiber amplification technology, Distributed Raman Amplification (DRA) technology has shown obvious advantages in many aspects such as noise figure, nonlinear damage, gain bandwidth, etc., and has gained advantages in the field of optical fiber communication and sensing. widely used. High-order DRA can make the gain deep into the link to achieve quasi-lossless optical transmission (that is, the best balance of optical signal-to-noise ratio and nonlinear damage), and significantly improve the overall balance of optical fiber transmission/sensing. Compared with conventional high-end DRA, DRA based on ultra-long fiber laser simplifies the system structure, and has the advantage of gain clamp production, showing strong application potential. However, this amplification method still faces bottlenecks that restrict its application to long-distance optical fiber transmission/sensing

ASE broadband light sources generate amplified spontaneous emission through rare-earth doped fibers (e.g., erbium-doped). Pumped by semiconductor lasers, excited ions emit photons, which are amplified to form a broad, flat spectrum (typically covering C-band 1530-1565nm and L-band 1565-1625nm) via gain-flattening filters.

Laser distance measuring is measured using a laser as a light source.It is divided into continuous laser and pulse laser according to the mode of laser operation.Gas lasers like helium-neon, argon ion, krypton cadmium and so on work in a continuous output state for phase laser ranging, dual heterogeneous GaAs semiconductor laser for infrared ranging; solid laser such as ruby, neodymium glass, for pulse laser ranging.Laser rangefinder due to the characteristics of good monochromy and strong orientation of laser, coupled with the semiconductor integration of electronic lines, compared with the photoelectric rangefinder, it can not only work day and night, but also improve the rangefinder accuracy.

At present, China has become the world's largest manufacturing country, and the domestic market has an increasingly strong demand for laser technology products. Since 2010, thanks to the continuous expansion of the laser processing application market, China's laser industry has gradually entered a period of rapid development. In 2018, the scale of China's laser equipment market reached 60.5 billion yuan, a year-on-year increase of 22.22%, and the compound growth rate from 2011 to 2018 reached 26.45%. China Business Industry Research Institute predicts that China's laser equipment market will reach 98.8 billion yuan in 2021.
