1576nm 10mW DFB Butterfly Laser Diode Manufacturers

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.

In scenarios where fiber optic sensor networks monitor the structural health of bridges and medical OCT equipment captures micron-level retinal lesions, SLED broadband light sources, with their ultra-wide spectrum, low coherence, and high stability, have become core components supporting high-precision optical systems. As a special light source between laser diodes and light-emitting diodes, these devices, through their unique light-emitting mechanism and circuit design, provide irreplaceable optical solutions for industrial monitoring, biomedicine, and national defense research.

The wavelength of a laser describes the spatial frequency of the emitted light wave. The optimal wavelength for a specific use case depends heavily on the application. During material processing, different materials will have unique wavelength absorption characteristics, resulting in different interactions with the materials. Likewise, atmospheric absorption and interference can affect certain wavelengths differently in remote sensing, and in medical laser applications, different skin colors will absorb certain wavelengths differently. Shorter wavelength lasers and laser optics have advantages in creating small, precise features that generate minimal peripheral heating due to smaller focused spots. However, they are generally more expensive and more susceptible to damage than longer-wavelength lasers.

Since Maman first obtained laser pulse output in 1960, the process of human compression of laser pulse width can be roughly divided into three stages: Q-switching technology stage, mode-locking technology stage, and chirped pulse amplification technology stage. Chirped pulse amplification (CPA) is a new technology developed to overcome the self-focusing effect generated by solid-state laser materials during femtosecond laser amplification. It first provides ultra-short pulses generated by mode-locked lasers. "Positive chirp", expand the pulse width to picoseconds or even nanoseconds for amplification, and then use the chirp compensation (negative chirp) method to compress the pulse width after obtaining sufficient energy amplification. The development of femtosecond lasers is of great significance.
