Abstract

A beam integrator system is disclosed, which integrates multiple beams into fewer beams of increased intensity by using a combination of optical elements and lenses.

Claims

exact text as granted — not AI-modified
1 . An apparatus configured to integrate a plurality of beams to form a beam with a near circular cross-section, comprising: 
 means for rotating beams by an angle to obtain associated rotated beams, wherein the beams are generated by a plurality of emitters;    means for combining the associated rotated beams by passing the associated rotated beams through a positive lens to form at least one combined beam; and    means for varying the cross section of the combined beam, by passing the at least one combined beam through an anamorphic lens.    
     
     
         2 . The apparatus of  claim 1 , wherein the means for rotating beams includes an asymmetric prism.  
     
     
         3 . The apparatus of  claim 1 , wherein the means for rotating beams includes a dove prism.  
     
     
         4 . The apparatus of  claim 3 , further comprising: 
 an integrator a beam combining lens; and    an anamorphic lens.    
     
     
         5 . The apparatus of  claim 1 , wherein the means for rotating beams includes at least one element having a positive optical power.
