Place lamb chops on a lightly oiled rack in a broiler pan. Broil about 4-inches below heat, turning once, until well browned on both sides but still pink in center;about 8 to 10 minutes. Cut to test.
Meanwhile, in a wide frying pan, combine sugar, vinegar, onion, raisins, cinnamon, and ginger. Cook over medium-high heat, stirring occasionally, until onion is softened, about 5 minutes. Add papaya and stir gently until heated through, about 3 minutes.
Transfer chops to a platter; spoon papaya mixture over chops. Serve Season Yogurt and cucumber strips alongside.
