For spectral synthesis technology, increasing the number of synthesized laser sub-beams is one of the important ways to increase the synthesis power. Expanding the spectral range of fiber lasers will help increase the number of spectral synthesis laser sub-beams and increase the spectral synthesis power [44-45]. At present, the commonly used spectrum synthesis range is 1050～1072 nm. Further expanding the wavelength range of narrow linewidth fiber lasers to 1030 nm is of great significance to the spectrum synthesis technology. Therefore, many research institutions have focused on short wavelength (wavelength less than 1040 nm) narrow line Wide fiber lasers were studied. This paper mainly studies the 1030 nm fiber laser, and extends the wavelength range of the spectrally synthesized laser sub-beam to 1030 nm.

When the incident light flux leaves from the illuminated surface or the incident surface of the medium to the other side, the ratio of the radiant energy projected and transmitted through the object to the total radiant energy projected on the object is called the transmittance of the object. The percentage of radiant energy reflected by an object to the total radiant energy is called reflectivity.

The grating coupler uses grating technology to couple optical signals into optical fibers, and uses the principle of grating diffraction to connect the transmitted optical signals with the optical field inside the optical fiber. The fundamental principle is to use high-frequency acoustic wave fields as gratings to divide light waves into many small light waves, and project them into optical fibers, thereby realizing the coupling and transmission and reception of optical signals.
