Dabarun zaɓi bisa ga yanayin aikace-aikace
Bukatun aiki donna'urorin laserya bambanta sosai a cikin yanayi daban-daban na aikace-aikace. Mataki na farko a cikin zaɓe shine a fayyace ainihin buƙatun aikace-aikacen.
Sarrafa kayan aiki daidai da kuma kera ƙananan nano: Irin waɗannan aikace-aikacen sun haɗa da yankewa mai kyau, haƙa rami, yanke wafer na semiconductor, alamar matakin micron da bugu na 3D, da sauransu. Suna da buƙatu masu yawa don ingancin katako da girman tabo mai da hankali. Ya kamata a zaɓi laser mai factor M² kusa da 1 (kamar <1.1). Ana buƙatar ƙayyade ƙarfin fitarwa bisa ga kauri kayan da saurin sarrafawa. Gabaɗaya, wutar lantarki daga goma zuwa ɗaruruwan watts na iya biyan buƙatun yawancin micro-processor. Dangane da tsawon rai, 1064nm shine zaɓi mafi kyau ga yawancin sarrafa kayan ƙarfe saboda yawan shan sa da ƙarancin farashi a kowace watt na ƙarfin laser.
Binciken kimiyya da kuma aunawa mai zurfi: Yanayin aikace-aikacen sun haɗa da na'urorin hangen nesa, kimiyyar atom mai sanyi, spectroscopy mai ƙuduri mai girma da kuma interferometry. Waɗannan fannoni galibi suna da matuƙar bin diddigin monochromaticity, kwanciyar hankali na mita da aikin hayaniyar lasers. Ya kamata a ba wa samfuran da ke da faɗin layi mai kunkuntar (ko da mita ɗaya) da kuma ƙaramar amo mai ƙarfi fifiko. Ya kamata a zaɓi tsawon tsayin daka bisa layin resonance na takamaiman atom ko molecule (misali, ana amfani da 780nm don sanyaya atom ɗin rubidium). Fitowar kulawa ta bias yawanci tana da mahimmanci don gwaje-gwajen tsangwama. Bukatar wutar lantarki gabaɗaya ba ta da yawa, kuma ɗaruruwan milliwatts zuwa watts da yawa sau da yawa sun isa.
Likitanci da fasahar kere-kere: Aikace-aikacen sun haɗa da tiyatar ido, maganin fata da kuma hoton na'urar hangen nesa ta fluorescence. Tsaron ido shine babban abin da ake la'akari da shi, don haka ana yawan zaɓar na'urorin laser masu tsawon tsayi na 1550nm ko 2μm, waɗanda ke cikin madaurin tsaron ido. Don aikace-aikacen ganewar asali, ana buƙatar a kula da daidaiton wutar lantarki; Don aikace-aikacen warkewa, ya kamata a zaɓi ƙarfin da ya dace bisa ga zurfin magani da buƙatun kuzari.

Idan aka fuskanci ma'anoni da dama, za a iya yanke shawara bisa ga waɗannan abubuwan da suka fi muhimmanci:
Sigogi masu yanke shawara: Da farko, ƙayyade tsawon tsayi da ingancin katako. Ana ƙayyade tsawon tsayin ta hanyar muhimman buƙatun aikace-aikacen (halayen sha na abu, ƙa'idodin aminci, layukan amsawar atomic), kuma yawanci babu sarari don yin sulhu. Ingancin katako kai tsaye yana ƙayyade yuwuwar amfani da shi. Misali, injinan daidai ba za su iya karɓar lasers masu girman M² ba.

Ana ƙayyade halayen faɗin layi da rarrabawa bisa ga takamaiman hanyar fasaha ta aikace-aikacen (kamar ko tsangwama ko ninka mita yana da hannu). Sigogi masu amfani: A ƙarshe, a yi la'akari da kwanciyar hankali (kamar kwanciyar hankali na wutar lantarki na dogon lokaci), aminci (lokacin aiki mara matsala), amfani da wutar lantarki mai yawa, dacewa da haɗin kai da farashi. Waɗannan sigogi suna shafar wahalar haɗakarwa da jimlar farashin mallakar laser a cikin yanayin aiki na gaske.

3. Zaɓa da hukunci tsakanin yanayi ɗaya da yanayi da yawa
