Ko te karaihe BBO i roto i te karaihe whatu kore raina, he momo painga matawhānui e kitea ana, he karaihe pai, he tino whanui te awhe marama, he iti rawa te whakaurunga whakarea, he ngoikore te awe piezoelectric, e pa ana ki etahi atu karaihe hurihuri hiko, he teitei ake te owehenga o te mate, he nui ake te rite. Ko te koki, te paepae kino o te marama, te taurite o te pāmahana aunui me te tino riterite o nga whatu, he pai ki te whakapai ake i te mana o te mana whakaputa taiaho, ina koa mo te Nd: YAG laser e toru nga wa he nui te tono.
