The invention discloses a laser beam combining device and system, and belongs to the technical field of laser, the laser beam combining device comprises a first prism and a second prism, the incident laser type and the distance d of each prism are adjustable, the incident laser of any prism is flexibly controlled in the beam combining process by adjusting the distance d, and the laser beam combining efficiency is improved. The incident laser can be partially converged, completely converged or not converged to output beam-combined laser, so that beam combination as required is realized; meanwhile, the device does not depend on an optical grating, but adopts a prism for beam combination, and can bear beam-combined laser with higher power; the laser does not pass through any curved surface, does not generate diffraction, does not introduce additional aberration, can ensure that the combined laser still has better beam quality, and does not have requirements on the spectrum, polarization and wavelength of each in
