I understand how diodes work and what they do, but looking at the schematic for the DDL driver, the diode appears to just short out the battery if it was hooked up backwards. And it looks like you are basically hoping the diode is ok and shorts the battery out before any voltage/current can continue on the straight path to the LD. Wouldn't 2 diodes, 1 on each LD lead facing the proper way be better protection? Is the single one done just to save space?
