He laser paʻa palekana ia me ka 1535nm ka lōʻihi o ka hawewe.Loaʻa iā ia nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi, ka hoʻohana haʻahaʻa haʻahaʻa, ka hilinaʻi kiʻekiʻe a me ke kūpaʻa maikaʻi, nā ʻano wela like ʻole, e hōʻoiaʻiʻo ana he laser palekana, kūpono a paʻa.
Hoʻohana ʻo ia i ka LD pumped erbium laser me ka 1.4 ~ 2.0μm maka palekana ka lōʻihi o ka hawewe, ua kokoke kona ʻano optical i ka palena palena o ka diffraction.
