Abstract:
A system for generating a plurality of laser beams that have substantially an equal amount of power, the system comprising:a laser source, the laser source configured to an initial beam comprising P wavelengths, where P is an integer; a wavelength splitter assembly positioned to receive the initial beam from the laser source and configured to the initial beam into N intermediate beams, where N is an integer and N&lE;P, each intermediate beam comprising at least one wavelength; and Nâ€² energy splitter assemblies, where Nâ€² is an integer and Nâ€²&lE;N, each energy splitter assembly positioned to receive one of the intermediate beams and configured to split one of the intermediate beams into ni divisional beams, where ni is an integer, each of the ni divisional beams having substantially an equal amount of power, whereby a total number of beams is determined with an equation, the equation being: K=N-Nâ€²+&Sum;i=1i=Nâ€²&it;niwhere K is an integer.
