He aha te rēseri cryogenic?

Ehara i te mea hou te ariā o ngā taiaho e mahi ana i ngā pāmahana iti: ko te tuarua o ngā taiaho i roto i te hītori he cryogenic. I te tīmatanga, he uaua te whakatutuki i te ariā ki te mahi i te pāmahana rūma, ā, i tīmata te hihiri mō te mahi pāmahana iti i te tekau tau atu i 1990 me te whanaketanga o ngā taiaho me ngā whakakaha kaha-tiketike.

I te mana teiteingā pūtake taiaho, ka pāngia te mahi a ngā pānga wera pēnei i te ngaronga o te depolarization, te piko o te arotahi wera, te karaihe laser rāneipūtake māramaMā te whakamatao i te pāmahana iti, ka taea te pehi i ngā pānga kino o te wera, arā, me whakamatao te reo whakanui ki te 77K, ki te 4K rānei. Ko te pānga whakamatao ko:

Ka tino āraihia te kawe hiko āhua o te reo whakanui, nā te mea kua piki ake te ara kore utu toharite o te taura. Nō reira, ka tino heke te pikinga pāmahana. Hei tauira, ina whakahekehia te pāmahana mai i te 300K ki te 77K, ka piki ake te kawe hiko wera o te karaihe YAG mā te whitu tau.

Ka heke nui hoki te tauwehenga horapa wera. Nā tēnei, me te hekenga o te pikinga pāmahana, ka heke te pānga arotahi wera, ā, ka iti ake te tūponotanga o te pakaru o te ahotea.

Ka whakaitihia hoki te tauwehenga wera-whatu, ka whakaitihia anō te pānga o te arotahi wera.

Ko te pikinga o te wāhanga whakawhiti mimiti o te katote whenua onge te take matua o te hekenga o te whānui i puta mai i te pānga wera. Nō reira, ka whakaitihia te mana kōtui, ka piki ake hoki te whakanui taiaho. Nō reira, ka whakaitihia te mana papu paepae, ā, ka taea te whiwhi i ngā pāoro poto ake ina mahi ana te pana Q. Mā te whakanui ake i te tuku o te hononga putanga, ka taea te whakapai ake i te whai huatanga o te pari, nō reira ka iti ake te hiranga o te pānga ngaronga kōhao pirinoa.

Ka whakaitihia te maha o ngā matūriki o te taumata iti katoa o te reo whakanui taumata-toru, nō reira ka whakaitihia te mana papu paepae, ā, ka whakapaitia te whai huatanga o te mana. Hei tauira, ko te Yb:YAG, e whakaputa ana i te mārama i te 1030nm, ka kitea he pūnaha taumata-toru i te pāmahana rūma, engari he pūnaha taumata-whā i te 77K. Er: He rite tonu te āhua mō te YAG.

I runga i te reo whakanui, ka whakaitihia te kaha o ētahi tukanga tinei.

Mā te whakamahi i ngā āhuatanga o runga ake nei, ka taea e te mahi pāmahana iti te whakapai ake i te mahi a te taiaho. Ina koa, ka taea e ngā taiaho whakamatao pāmahana iti te whakaputa i te mana whakaputa tino teitei me te kore he pānga wera, arā, ka taea te whiwhi kounga hihi pai.

Ko tētahi take hei whakaaroaro māu, i roto i tētahi karaihe taiaho whakamatao-makariri, ka whakaitihia te whānui o te mārama i whakawāteatia me te mārama i mimitia, nō reira ka whaiti ake te whānuitanga o te whakatikatika roangaru, ā, ka kaha ake te whānui o te rārangi me te pumau o te roangaru o te taiaho i whakapaoatia. Heoi, he onge noa iho tēnei pānga.

Ko te whakamatao cryogenic he tikanga e whakamahi ana i te wai whakamatao, pērā i te hauota wai, te herium wai rānei, ā, ko te mea pai ko te hurihanga o te hau whakamatao mā roto i te ngongo e piri ana ki te tioata laser. Ka whakakīia anō te wai whakamatao i roto i te wā, ka hangarua rānei i roto i te porowhita kati. Hei karo i te whakapakeketanga, he mea tika kia whakanohoia te tioata laser ki roto i te rūma korehau.

Ka taea hoki te whakamahi i te ariā o ngā tioata taiaho e mahi ana i ngā pāmahana iti ki ngā whakakaha. Ka taea te whakamahi i te hapaira titanium hei hanga whakakaha urupare pai, ko te mana putanga toharite i roto i ngā tekau watts.

Ahakoa ka taea e ngā taputapu whakamatao cryogenic te whakararurarungā pūnaha taiaho, he maha ngā wā kāore i te tino māmā ngā pūnaha whakamatao noa, ā, mā te whai huatanga o te whakamatao cryogenic ka taea te whakaiti i te uauatanga.
