         21 . A method comprising:
 using a laser to form a window extending through a casing installed in a wellbore;   inserting a piece of downhole equipment into the wellbore; and   engaging the window formed in the wall of the wellbore with the piece of downhole equipment.   
     
     
         22 . The method of  claim 21 , wherein using the laser to form the window comprises using the laser to form a window sized to receive a wellbore liner junction. 
     
     
         23 . The method of  claim 22 , comprising deploying the junction into the wellbore such that the junction is aligned with the window; and inserting the junction into and extending through the window. 
     
     
         24 . The method of  claim 23 , comprising sealing the window after inserting the junction into and extending through the window. 
     
     
         25 . The method of  claim 22 , wherein the using the later to form the window comprises using the laser to form a window for lateral wellbore off the wellbore. 
     
     
         26 . The method of  claim 21 , comprising deploying the piece of downhole equipment through the window.
