Gyrotron and for (hiflerclll planes phase reconstruction has 1ecii done. The Iterative
Phase Retrieval Algorithm for Gyrotrouus employ a iuuinerical solutiouu which

reconstruction is aclmieve(l by Iterative or Error reduction method in this case. The
Phase recoiust riicl ion provide profile (1esigning of internal mode converter reflectors
amid matching optical unit (MOU) for Grotrons. The MOU with two mirror systeiui
is designed to correct the beani parameters like astigmatism and cllipticity. The
(orrect beam contains alnuost ideal gaussian (ontent. as uiiore than 99 Y pure l-IE1 . i
