“…To solve this problem, the virtual transmission method based on 4F system is used to obtain the enlarged complex amplitude distribution E p (x,y) at the conjugated position of the end surface of the fiber core in each channel [18]. The coefficient c mp of mth-order mode on pth channel can be calculated by the cross-correlation degree [23].…”

Four-channel off-axis holography is proposed to simultaneously understand the polarization states and the mode coefficients of LP modes in few-mode fiber. Far-field off-axis holograms in the four-polarization directions of the fiber laser were acquired at the same moment through a four-channel holographic device. The weights, the relative phase differences and the polarization parameters of the vector fiber laser mode can be solved simultaneously. The simulated and experimental mode analysis of the laser output by 1060-XP fiber with 6 LP modes at 632.8nm are conducted, which shows that the similarity of the total intensity distribution of the laser before and after mode analysis is above 0.97. The mode polarization states, the mode weights and the relative phase differences of the few-mode laser can be determined simultaneously in a single shot by the four-channel off-axis holography.

Four-channel off-axis holography is proposed to simultaneously understand the polarization states and the mode coefficients of linearly polarized (LP) modes in few-mode fiber. Far-field off-axis holograms in the four polarization directions of the fiber laser were acquired at the same moment through a four-channel holographic device. The weights, the relative phase differences, and the polarization parameters of the vector fiber laser mode can be solved simultaneously.
