Optical array technology is an attractive method of achieving high power output using diode bars, which is different from using traditional diode stacks. Reflectors are the main optical elements in optical array diode lasers, and their influences of alignment errors on the output beam are analyzed using the matrix method. Analytical expressions of the beam size and deviation influenced by the misalignment of the reflectors are deduced, and the misalignment tolerances are also given. Based on the results, it is helpful to adjust the reflectors to achieve an output beam of good beam quality from the optical array diode lasers.
