In this article we have designed a new type of prismatic telescope which can be used to amplify the divergence of the laser beam. Theoretical analysis and computer analog indicate that the divergence multiplication factor is independent of the distance between the prismatic telescope and the waist of the laser beam, and the original divergence of the laser beam in 20 mrad, the laser beam as it passes through the prismatic telescope is still Gaussian beam. We have made and measured the prismatic telescope and found the result agrees with our theoretical analysis.
