Bokamoso ba ho sebetsa ka ho nepahala ho potlakileng haholo

Ho sebetsa ka ho nepahala ke karolo ea bohlokoa ea tlhahiso ea laser. E ntlafalitsoe ho tloha ho li-laser tsa pele tse tiileng tsa nanosecond green/ultraviolet ho ea ho li-laser tsa picosecond le femtosecond, 'me joale li-laser tsa ultrafast ke tsona tse ka sehloohong. Mokhoa oa nts'etsopele ea nakong e tlang oa ho sebetsa ka ho nepahala ha ultrafast e tla ba ofe?

Li-laser tse potlakileng haholo e bile tsa pele ho latela tsela ea theknoloji ea laser e tiileng. Li-laser tse tiileng li na le litšobotsi tsa matla a tlhahiso e phahameng, botsitso bo phahameng le taolo e ntle. Ke tsoelo-pele ea ntlafatso ea li-laser tse tiileng tsa nanosecond/sub-nanosecond, kahoo li-laser tse tiileng tsa picosecond femtosecond li nkela sebaka sa li-laser tse tiileng tsa nanosecond lia utloahala. Li-laser tsa faeba lia ratoa, li-laser tse potlakileng haholo le tsona li se li lebile lehlakoreng la li-laser tsa faeba, 'me li-laser tsa faeba tsa picosecond/femtosecond li hlahile ka potlako, li qothisana lehlokoa le li-laser tse tiileng tsa ultrafast.

Tšobotsi ea bohlokoa ea li-laser tse potlakileng ke ntlafatso ho tloha ho infrared ho ea ho ultraviolet. Ts'ebetso ea laser ea picosecond ea infrared e na le phello e batlang e phethahetse ho seheng le ho chekeng khalase, li-substrate tsa ceramic, ho seheng oafer, jj. Leha ho le joalo, leseli la ultraviolet tlas'a tlhohonolofatso ea li-pulse tse khutšoane haholo le ka finyella "ts'ebetso e batang" ho isa tekanyong e kholo, 'me ho phunya le ho seha thepa ha ho na matšoao a ho chesa, ho fihlela ts'ebetso e phethahetseng.

Mokhoa oa katoloso ea theknoloji ea laser ea pulse e khutšoanyane haholo ke ho eketsa matla , ho tloha ho li-watts tse 3 le li-watts tse 5 matsatsing a pele ho ea boemong ba hona joale ba li-watts tse 100. Hona joale, ts'ebetso e nepahetseng 'marakeng ka kakaretso e sebelisa li-watts tse 20 ho isa ho tse 50 tsa matla. 'Me setheo sa Jeremane se qalile ho sebetsana le bothata ba li-laser tse potlakileng tsa boemo ba kilowatt. S&A sesebelisoa sa laser se potlakileng haholo letoto lena le ka fihlela litlhoko tsa ho phodisa tsa boholo ba di-laser tse potlakileng haholo tse teng 'marakeng, le ho ntlafatsa mohala wa dihlahiswa tsa S&A chiller ho latela diphetoho tsa mmaraka.

Ka lebaka la mabaka a kang COVID-19 le tikoloho e sa tsitsang ea moruo, tlhoko ea lisebelisoa tsa elektroniki tsa bareki tse kang lioache le matlapa e tla fokotseha ka 2022, 'me tlhoko ea li-laser tse potlakileng ho PCB (boto ea potoloho e hatisitsoeng), liphanele tsa pontšo le LED li tla fokotseha. Ke masimo a selikalikoe le a chip feela a tsamaisitsoeng, 'me machining ea ho nepahala ha laser e potlakileng haholo e kopane le liphephetso tsa kholo.

Tsela ea ho tsoa bakeng sa li-laser tse potlakileng haholo ke ho eketsa matla le ho nts'etsapele maemo a mangata a ts'ebeliso. Li-picosecond tse lekholo li tla ba tse tloaelehileng nakong e tlang. Sekhahla se phahameng sa ho pheta-pheta le li-laser tse nang le matla a phahameng a ho otla li nolofalletsa bokhoni bo boholo ba ts'ebetso, joalo ka ho seha le ho cheka khalase ho fihlela botenya ba 8 mm. Laser ea picosecond ea UV ha e na khatello ea mocheso 'me e loketse ho sebetsana le lisebelisoa tse bonolo haholo, joalo ka li-stent tsa ho seha le lihlahisoa tse ling tsa bongaka tse bonolo haholo.

Ho kopanyeng le tlhahisong ea lihlahisoa tsa elektroniki, lefapheng la lifofane, la bongaka, la semiconductor wafer le liindastering tse ling, ho tla ba le palo e kholo ea litlhoko tsa ho sebetsa ka nepo bakeng sa likarolo, 'me ts'ebetso ea laser e sa amaneng e tla ba khetho e ntle ka ho fetisisa. Ha tikoloho ea moruo e qala, ts'ebeliso ea laser e potlakileng ka ho fetisisa e tla khutlela tseleng ea kholo e phahameng.
