The UV lasers-splitter can split a beam of UV laser into several ones with identical intensity and wide application prospects have been found in many situations that need to split a beam of laser, such as image multipliers and optical information process. The UV lasers-splitters is a binary rectangular phase grating. In this paper, the intensity formulae of series diffracting waves of the binary phase grating are obtained from the general complex amplitude transmissions formulae through Fourier integral. This approach simplifies the process of calculation and provides a optimal operation of the design.
