Ikusasa lomshini wokulungisa ngokunemba okusheshayo

Umshini wokulungisa ngokunemba uyingxenye ebalulekile yokukhiqiza nge-laser. Usuthuthuke kusukela kuma-laser aqinile e-nanosecond green/ultraviolet okuqala kuya kuma-laser e-picosecond kanye ne-femtosecond, futhi manje ama-laser e-ultrafast yiwona ahamba phambili. Kuzoba yini ukuthambekela kwentuthuko yesikhathi esizayo yomshini wokulungisa ngokunemba we-ultrafast?

Ama-laser e-Ultrafast abe ngawokuqala ukulandela umzila wobuchwepheshe be-laser ye-solid-state. Ama-laser e-Solid-state anezici zamandla aphezulu okukhipha, ukuzinza okuphezulu kanye nokulawula okuhle. Angukuqhubeka kokuthuthukiswa kwama-laser e-solid-state e-nanosecond/sub-nanosecond, ngakho-ke ama-laser e-picosecond femtosecond solid-state athatha indawo yama-nanoseconds ama-solid-state lasers anengqondo. Ama-laser e-fibre athandwa kakhulu, ama-laser e-ultrafast nawo asuke aqonde ngqo kuma-laser e-fiber, kanti ama-laser e-picosecond/femtosecond fiber avele ngokushesha, encintisana nama-laser e-solid ultrafast.

Isici esibalulekile sama-laser asheshayo ukuthuthukiswa kusuka ku-infrared kuya ku-ultraviolet. Ukucutshungulwa kwe-laser ye-picosecond ye-infrared kunomphumela ocishe ube mhle kakhulu ekusikeni nasekubholeni ingilazi, kuma-substrate e-ceramic, ekusikeni kwe-wafer, njll. Kodwa-ke, ukukhanya kwe-ultraviolet ngaphansi kwesibusiso sama-pulse amafushane kakhulu kungafeza "ukucutshungulwa okubandayo" kakhulu, futhi ukubhoboza nokusika ezintweni akunawo amamaki okusha, okufeza ukucutshungulwa okuphelele.

Umkhuba wokwanda kobuchwepheshe be-laser ye-pulse emfushane kakhulu ukwandisa amandla , kusukela kuma-watts angu-3 nama-watts angu-5 ezinsukwini zokuqala kuya ezingeni lamanje lama-watts angu-100. Njengamanje, ukucubungula ngokunemba emakethe ngokuvamile kusebenzisa ama-watts angu-20 kuya kwangu-50 wamandla. Futhi isikhungo saseJalimane sesiqalile ukubhekana nenkinga yama-laser e-ultrafast asezingeni le-kilowatt. I-S&A i-laser chiller esheshayo kakhulu Uchungechunge lungahlangabezana nezidingo zokupholisa zama-laser amaningi asheshayo emakethe, futhi lucebise umugqa womkhiqizo we-S&A chiller ngokuya ngezinguquko zemakethe.

Ithintwe yizici ezifana ne-COVID-19 kanye nesimo sezomnotho esingaqinisekile, isidingo sezinto zikagesi zabathengi ezifana namawashi namathebulethi sizoncipha ngo-2022, kanti isidingo sama-laser asheshayo ku-PCB (ibhodi lesifunda eliphrintiwe), amaphaneli okubonisa kanye ne-LED sizoncipha. Kuphela amasimu omjikelezo kanye nama-chip aqhutshwa, futhi imishini yokunemba kwe-laser eshesha kakhulu ihlangabezane nezinselele zokukhula.

Indlela yokuphuma kwama-laser asheshayo ukwandisa amandla nokuthuthukisa izimo zokusetshenziswa ezengeziwe. Ama-picosecond angamakhulu ama-watt azoba yinto ejwayelekile esikhathini esizayo. Izinga eliphezulu lokuphindaphinda kanye nama-laser anamandla okushaya kwenhliziyo aphezulu avumela amakhono amakhulu okucubungula, njengokusika nokubhoboza ingilazi efika ku-8 mm ubukhulu. I-laser ye-picosecond ye-UV ayinawo cishe ukucindezeleka kokushisa futhi ifanelekela ukucubungula izinto ezizwela kakhulu, njenge-stent yokusika kanye neminye imikhiqizo yezokwelapha ezizwela kakhulu.

Ekuhlanganisweni nasekukhiqizweni kwemikhiqizo kagesi, ezindizayo, kwezokwelapha, kwe-semiconductor wafer nakwezinye izimboni, kuzoba nenani elikhulu lezidingo zomshini wokunemba wezingxenye, futhi ukucubungula i-laser engathintani kuzoba yisinqumo esihle kakhulu. Lapho isimo sezomnotho siqala, ukusetshenziswa kwama-laser asheshayo kuzobuyela endleleni yokukhula okuphezulu.
