He aha te Laser
He maama te taiaho ma te tango i te kaha o te hiko.Ko te iraruke taiaho he mea hanga e te puna taiaho, a ka whakahihiko te kaha o te kaha o te kaha ki nga rakau karaihe (nga taiaho ahua-too) he ranunga hau motuhake ranei. ( lasers hau ) ki te whakaputa iraruke laser.Ka whakaratohia tenei kaha i roto i te ahua o te rama (rama rama, laser diode ranei) te tuku hiko ranei (he rite ki te rama rama).He rakau karaihe ranei Ko te hau whakahoahoa taiaho kei waenganui i nga whakaata e rua hei hanga i te kohao resonant taiaho hei arahi i te taiaho ki tetahi huarahi motuhake me te whakanui i te tohu whatu penei.Ka haere te laser na roto i te whakaata maramara i roto i tetahi waahanga ka whakamahia mo te tukatuka rauemi.Nga Tikanga o te Tukatuka Taiaho
Kei roto i nga lasers katoa nga waahanga e toru e whai ake nei: Pump source Stimulated medium Cavity resonant Ko te puna papu e tuku pūngao mai i te puna o waho ki te laser.Ko te reo hihiko kei roto i te laser.I runga i te hoahoa o te hanganga laser, ko te reo laser he ranunga hau (CO2 laser), he karaihe karaihe (YAG solid laser) he muka karaihe ranei. (taiaho muka).I te wa e whakawhiwhia ana te reo laser ki te kaha mai i tetahi puna papua o waho, ka harikoa ki te whakaputa iraruraru hiko.Ko te reo hihiko kei waenganui o nga whakaata e rua i nga pito e rua o te rua orooro.Ko tetahi o nga whakaata he arotahi kotahi (hawhe whakaata).Te iraruke hiko i hangaia e te ka whakanuia te reo hikaka i roto i te kohao haruru.I te wa ano, kotahi anake te mea motuhake Ka taea e te iraruke te haere ma te arotahi kotahi-ara ki te hanga i te kurupae o te iraruke, ko te taiaho.
E toru nga ahuatanga matua o te laser:Te tauritenga: kotahi anake te roangaru o te marama te iraruke taiaho Te whakakotahitanga: te wahanga kotahi Whakarara: He tino whakarara te rama i roto i te kurupae taiaho He tino whakarara te rama laser i mua i te whakawhiti i te arotahi arotahi.I roto i te roanga o te kurupae laser, ka puta te kaha o te kaha o te kaha, ka taea te whakamahi ki te whakarewa, ki te whakaeto ranei i nga rawa.I tua atu, ka taea e te whakamahi i nga huānga whatu tika (arotahi) te arahi me te whakaata i te rama laser, karekau he mate ahakoa i tawhiti.Ko te punaha tuunga (tohu taiaho) me te matawai galvanometer ka whakamahia hei punaha pūkoro.I te mea karekau te kurupae laser e pahemo, he taputapu mo te ao katoa, he kore kakahu-kore.
