Definition
The laser is a semiconductor laser employing a distributed feedback structure. It has a peak wavelength of 1330 nm and an output power of 300 mW. Its working principle is based on a distributed feedback mechanism, that is, integrating a Bragg grating within the active region of the laser. This grating reflects light of a specific wavelength to form a laser resonant cavity, thereby achieving single-mode laser output.
