CPCGs allow for manipulating the longitudinal power distribution in laser cavity to increase output power. By optimizing the grating ratio, >37.837% increase in output power and >97.3% single-mode-yield can be obtained even at high operation temperature.Realization of High-power DFB Lasers with Single and Multiple Partially Corrugated Gratingsconference paper10.23919/MOC58607.2023.103028842-s2.0-85179000036https://api.elsevier.com/content/abstract/scopus_id/85179000036
