Loaʻa i ka ʻenehana laser kekahi mau hiʻohiʻona kūʻokoʻa e pili ana i ka maikaʻi o kāna ʻoki.Ua ʻike ʻia ka diffraction o ka nui o nā lasers e hiki ai i nā pae kiʻekiʻe o ka māmā māmā ma nā mamao lōʻihi.Eia kekahi, nā hiʻohiʻona e like me ka monochromaticity e hoʻoholo i kakukuna laser' ke alapine o ka nalu, oiai ke ana ka lokahi i ke kulana mau o ka kukuna electromagnetic.Hoʻololi kēia mau mea e like me ke ʻano o ka laser i hoʻohana ʻia.ʻO nā ʻano maʻamau maʻamau o nā ʻōnaehana ʻokiʻoki laser ʻoihana:
Nd: YAG: Hoʻohana ka laser neodymium-doped yttrium aluminika garnet (Nd:YAG) i kahi mea aniani paʻa e kālele i ka mālamalama i kāna pahu hopu.Hiki iā ia ke puhi i ke kukui infrared mau a i ʻole rhythmic i hiki ke hoʻonui ʻia e nā mea hana lua, e like me nā kukui pumping optical a i ʻole diodes.ʻO ka Nd:YAG ka lāʻau ʻokoʻa a me ke kūlana kūlana kiʻekiʻe e hana maikaʻi loa i nā hana haʻahaʻa haʻahaʻa, e like me ke ʻoki ʻana i ka metala a i ʻole ke ʻoki ʻana i ke kila anana lahilahi.
CO2: ʻO ka laser Acarbon dioxide kahi mea ʻoi aku ka ikaika i ke kumu hoʻohālike Nd:YAG a hoʻohana i kahi mea kinoea ma kahi o ke aniani no ka nānā ʻana i ka mālamalama.ʻO kona hoʻopuka-a-pumping ratio hiki iā ia ke puhi i kahi kukui hoʻomau kiʻekiʻe e hiki ke ʻoki pono i nā mea mānoanoa.E like me ka hōʻike ʻana o kona inoa, ʻo ka hoʻokuʻu ʻana o ke kinoea laser he hapa nui o ka carbon dioxide i hui pū ʻia me ka liʻiliʻi o ka nitrogen, helium, a me ka hydrogen.Ma muli o kona ikaika ʻokiʻoki, hiki i ka laser CO2 ke hana i nā papa kila nui a hiki i ka 25 millimeters ka mānoanoa, a me ke ʻoki ʻana a i ʻole ke kahakaha ʻana i nā mea lahilahi ma ka mana haʻahaʻa.
