Abstract
A system and method for combining a predetermined number of laser beams. The system () includes a collimating lens () for receiving and collimating the laser beams and a holographic device () positioned to receive beams from the collimating lens () and output beams which are co-aligned. The holographic device () includes a predetermined number of holographic optical elements (), wherein each holographic optical element () is designed for a particular wavelength of the laser beams. In the preferred embodiment, the holographic optical elements are volume holograms, and the system further includes a blazed grating () positioned between the collimating lens () and the holographic device () to account for variations in the wavelengths of the laser beams due to environmental conditions.
