Abstract :
Summary form only given.This work demonstrates the use of interference effects in enhancing the coupling of an input laser beam into the tight cross-section of a periodically segmented KTiOPO/sub 4/ waveguide yielding a three fold increase in its SHG output. In combination with the differential heating technique reported earlier, the use of this technique can result in compact blue laser sources meeting the minimum power requirements for several applications.
