Abstract The single block crystal is designed to incldues one single grating area with non-linear optical characteristic along the first direction and at least one multiple grating area comprising several inner grating arranged parallelly in the second direction. Each of the inner gratings has non-linear optical characteristic along the first direction. The first direction is one for laser to travel and the second direction is perpendicular to the first one. The crystal of the present invention may be used to generate parallel and serial laser. In different temperature, one single grating and one optional inner grating in the multiple gratings may be quasi-phase matched to output laser of different wavelength.
