A. Te ariā o ngā taiaho tino tere
Ko ngā taiaho tere rawa e pā ana ki ngā taiaho raka-aratau e whakamahia ana hei tuku i ngā pāoro poto rawa, hei tauira, ngā pāoro o te roanga femtosecond, picosecond rānei. Ko te ingoa tika ake ko te taiaho pāoro poto rawa. Ko ngā taiaho pāoro poto rawa he taiaho tata raka-aratau, engari ka taea hoki e te pānga whakawhiti whakanui te whakaputa i ngā pāoro poto rawa.
B. Te momo taiaho tino tere
1. Ka taea e ngā taiaho ti-sapphire, ko te tikanga he Kerr arotahi-raka aratau, te whakaputa i ngā pāorooro poto noa iho i te 5 fs te roa. Ko te mana putanga toharite he rau miriwatiti noa iho, me ngā tere whakahoki pāorooro, hei tauira, 80MHz me ngā tekau femtohekona, iti iho rānei, me ngā roanga pāorooro o ngā tekau femtohekona, iti iho rānei, ka hua ake he mana tihi tino teitei. Engari ko ngā taiaho titanium-sapphire me pupuhi te mārama mai i ētahi taiaho rama-kakariki, ka nui ake te uaua me te utu nui.
2. He maha ngā momo taiaho papu-taio i ahu mai i, hei tauira, i ngā taiaho papu-ytterbium (kirihou, karāhe rānei) i pania ki te chromium, e whakamahi ana i te aratau maukati SESAM. Ahakoa kāore te roa o te pao o ngā taiaho papu-taio i te poto pērā i te roa o te pao o ngā taiaho titanium-sapphire, ka taea e ngā taiaho papu-taio te kapi i tētahi rohe tawhā whānui e pā ana ki te roa o te pao, te tere o te whakahokinga pao, me te mana toharite (tirohia i raro).
3. Ka taea hoki te whakakāhore i ngā reera muka i runga i ngā muka karāhe kua tāpirihia ki ngā huānga whenua onge, hei tauira, mā te whakamahi i te hurihanga polarization kore-raina, te SESAM rānei. He iti ake ēnei i ngā reera papatipu e pā ana ki te mana toharite, inā koa te mana tihi, engari ka taea te whakakotahi me ngā whakakaha muka. Kei te tuhinga mō ngā reera muka kua whakakāhoretia te aratau ētahi atu kōrero.
(4) ka taea e ngā taiaho taiaho raka-aratau te noho hei taputapu whakauru, hei taiaho taiaho kōhao-waho rānei, ā, ka taea te noho hei taiaho hohe, hei taiaho kore mahi, hei taiaho whakauru rānei. I te nuinga o te wā, ka mahi ngā taiaho taiaho raka-aratau i te tere auau pāoro teitei (e hia mano megahertz) i te kaha pāoro taurite.
Ka taea e ngā oscillator laser tino tere te whakauru ki ngā pūnaha laser tino tere, ka taea hoki te whakauru i tētahi whakakaha tere tino tere (pēnei i te whakakaha muka whatu) hei whakanui ake i te mana tihi me te mana putanga toharite.
