The 808nm pump light is focussed in the laser crystal, it's highly divergent. Because it's high power it does leak somewhat through. The 1064nm light has a high circulating power in the cavity. The mirrors are not perfect, so they pass some light through. This light is roughly collimated with the green and can be significant. But the actual values will differ per laser.
