  • The optical performance of green lasers is greatly improved

    Laser is considered to be one of the greatest inventions of mankind in the twentieth century, and its appearance has strongly promoted the progress of detection, communication, processing, display and other fields. Semiconductor lasers are a class of lasers that mature earlier and progress faster. They have the characteristics of small size, high efficiency, low cost, and long life, so they are widely used. In the early years, infrared lasers based on GaAsInP systems laid the cornerstone of the information revolution.

  • Important research achievements have been made in the field of new deep ultraviolet laser devices

    Recently, with the support of the National Natural Science Foundation of China, Shenzhen Basic Research and other projects, Assistant Professor Jin Limin, a member of Harbin Institute of Technology (Shenzhen) Micro-nano Optoelectronics team, cooperated with Professor Wang Feng and Professor Zhu Shide of City University of Hong Kong, and published a research paper in the internationally renowned journal Nature-Communications. Harbin Institute of Technology (Shenzhen) is the communication unit.

  • Amplified spontaneous emission ASE broadband light source

    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.

  • What are the principles and differences between 1st-order Raman Amplifier and 2nd-order Raman Amplifier?

    1st-order Raman spectroscopy utilizes stimulated Raman scattering in silica optical fibers. 140 nm pump light directly amplifies C-band signal light (1530-1565 nm). The pump light vibrates and scatters in the fiber, transferring energy to the frequency of the signal light.

  • 1.5 μm Band Single Frequency Fiber Laser

    Single-frequency lasers based on Er3+-doped or Er3+/Yb3+ co-doped gain fibers mainly work in the 1.5 μm band (C-band: 1530-1565 nm) and part of the L-band (1565-1625 nm). Its wavelength is in the C window of optical fiber communication, which makes the 1.5 μm band single-frequency fiber laser with narrow linewidth and low noise characteristics very important in coherent optical communication. It is used in high-resolution sensing, optical frequency domain reflectometer , laser radar and other fields also have a wide range of applications.
