Whakarāpopototanga Hangarau:
Ko te Pūnaha Tapahi Reihi Karāhe Pikohekona-Rua o te Infrared Picosecond he otinga taumata-ahumahi i hangaia mō te miihini tika o ngā rauemi mārama pakarukaru. He pūtake reihi pikohekona-rua infrared 1064nm (whānui pātere <15ps) me te hoahoa tūāpapa teihana-rua, ka tukuna e tēnei pūnaha he pai tukatuka rua, ka taea ai te miihini kore he o ngā karāhe whatu (hei tauira, BK7, silica hanumi), ngā tioata kuata, me te hapaira (α-Al₂O₃) me te pakeke tae atu ki te Mohs 9.
Ki te whakatauritea ki ngā taiaho nanohekona tuku iho, ki ngā tikanga tapahi ā-ringa rānei, ka tutuki i te Pūnaha Tapahi Taiaho Karāhe Teihana-Rua o te Infrared Picohekona te whānuitanga kerf taumata-micron (te whānuitanga noa: 20–50μm) mā te tikanga "whakakorenga makariri", me te rohe e pāngia ana e te wera e herea ana ki te <5μm. Ka whakanui ake te aratau mahi teihana-rua tauwhitiwhiti i te whakamahinga o ngā taputapu mā te 70%, ko te pūnaha whakarite tirohanga motuhake (tika tūnga CCD: ±2μm) he mea pai mō te hanga papatipu o ngā wāhanga karāhe piko 3D (hei tauira, te karāhe uhi waea atamai, ngā karāhe mataarataki) i roto i te umanga hikohiko kaihoko. Kei roto i te pūnaha ngā kōwae uta/tango aunoa, e tautoko ana i te hanga tonu 24/7.

· Ka uru te roangaru whero (1064nm) ki roto i ngā rauemi mārama mā te mimiti kore-raina, ka ārai i te tangohanga o te mata.
· Ka whakaputahia e te pūnaha whatu arotahi-maha motuhake e whā ngā wāhi tukatuka motuhake i te wā kotahi.

2. Pūnaha Tukutahitanga Teihana-Rua:
· Ngā wāhanga motuka raina takirua turanga-karaihe (tika tūnga: ±1μm).
· Te wā whakawhiti teihana <0.8s, e āhei ai ngā mahi "tukatuka-uta/tango" whakarara.
· Mā te whakahaere pāmahana motuhake (23±0.5°C) mō ia teihana ka pumau te mahi miihini mō te wā roa.

3. Mana Whakahaere Tukanga Atamai:
· Pūtake raraunga rauemi whakauru (200+ ngā tawhā karāhe) mō te taurite aunoa i ngā tawhā.
· Mā te aroturukitanga plasma wā-tūturu ka whakarerekētia te kaha o te taiaho (taumira whakarerekētanga: 0.1mJ).
· Ka whakaitihia e te ārai hau ngā kapiti moroiti o te taha (<3μm).
I roto i tētahi whakamahinga noa e whakamahi ana i te tapahi i te anga hapaira matotoru 0.5mm, ka eke te tere tapahi o te pūnaha ki te 300mm/s me ngā rahinga maramara <10μm, e tohu ana i te whakapainga whai huatanga e 5x atu i ngā tikanga tuku iho.

Ngā Painga Tukatuka

1. Pūnaha tapahi me te wehewehe teihana-rua kua whakauruhia mō te mahi ngāwari;
2. Mā te miihini tere-teitei o ngā āhuahanga matatini ka whakarei ake i te whai huatanga o te tukanga tahuritanga;
3. Ngā tapa tapahi kāore he whakarara, he iti noa te pakaru (<50μm) ā, he haumaru te whakahaere mā te kaiwhakahaere;
4. Whakawhiti maeneene i waenga i ngā whakatakotoranga hua me te mahi māmā;
