In today's era of rapid development of laser technology, solid-state lasers and fiber lasers, as the two major mainstream laser products, have each demonstrated their unique charm and advantages in many fields such as industrial production, scientific research, and military applications.

The SLED light source is an ultra-wideband light source designed for special applications such as sensing, fiber optic gyroscopes, and laboratories.

When using laser as a carrier wave for communication or tools for processing, medical treatment, sensing, and detection, it is usually necessary to manage the polarization state of the laser. If the system needs to maintain a certain special polarization state of the laser, in the case of non-free space, the polarization-maintaining fiber or the circular-preserving fiber will be a practical solution to maintain the laser polarization state in a closed channel mode.

Depending on the active region material, the band gap width of the semiconductor material of the blue light semiconductor laser varies, so the semiconductor laser can emit light of different colors. The active region material of the blue light semiconductor laser is GaN or InGaN.

Fluorescence imaging has been widely used in biomedical imaging and clinical intraoperative navigation. When fluorescence propagates in biological media, absorption attenuation and scattering disturbance will cause fluorescence energy loss and signal-to-noise ratio decrease, respectively. Generally speaking, the degree of absorption loss determines whether we can "see", and the number of scattered photons determines whether we can "see clearly". In addition, the autofluorescence of some biomolecules and signal light are collected by the imaging system and eventually become the background of the image. Therefore, for biofluorescence imaging, scientists are trying to find a perfect imaging window with low photon absorption and sufficient light scattering.
