Bokamoso ba machining a ultrafast precision

Precision machining ke karolo ea bohlokoa ea tlhahiso ea laser. E tsoetse pele ho tloha ho li-lasecond tse tala tse tiileng tsa nanosecond ho isa ho li-laser tsa picosecond le tsa femtosecond, 'me joale li-lasers tsa ultrafast ke tsona tse ka sehloohong. Mokhoa oa nakong e tlang oa nts'etsopele ea mochini oa ultrafast precision e tla ba ofe?

Li-laser tsa Ultrafast e bile tsona tsa pele tsa ho latela tsela ea theknoloji ea laser e tiileng. Li-lasers tsa boemo bo tiileng li na le litšobotsi tsa matla a phahameng a hlahisoang, botsitso bo phahameng le taolo e ntle. Ke tsoelopele ea ntlafatso ea li-laser tsa nanosecond/sub-nanosecond solid-state, kahoo li-laser tsa picosecond femtosecond solid-state li nka sebaka sa nanoseconds solid-state lasers lia utloahala. Li-laser tsa fiber li tumme, li-laser tsa ultrafast le tsona li se li lebile moo ho nang le li-laser tsa fiber, 'me li-laser tsa picosecond/femtosecond li hlahile ka potlako, li qothisana lehlokoa le li-laser tse tiileng tsa ultrafast.

Tšobotsi ea bohlokoa ea li-lasers tsa ultrafast ke ho ntlafatsa ho tloha ho infrared ho ea ho ultraviolet. Ts'ebetso ea laser ea infrared picosecond e na le phello e batlang e phethahetse ho seheng le ho cheka likhalase, li-substrates tsa ceramic, sehiloeng sa wafer, jj. Leha ho le joalo, leseli la ultraviolet tlas'a tlhohonolofatso ea li-ultra-short pulses li ka finyella "ts'ebetso e batang" ho ea ka mokhoa o feteletseng, 'me ho phunya le ho itšeha ka thepa ho na le hoo e ka bang ha ho na matšoao a ho chesa, ho finyella ts'ebetso e phethahetseng.

Mokhoa oa katoloso ea theknoloji ea ultra-short pulse laser ke ho eketsa matla , ho tloha ho 3 watts le 5 watts matsatsing a pele ho ea boemong ba hona joale ba 100 watts. Hajoale, ts'ebetso e nepahetseng 'marakeng hangata e sebelisa li-watts tse 20 ho isa ho tse 50 tsa matla. 'Me setsi sa Jeremane se se se qalile ho sebetsana le bothata ba li-laser tsa ultrafast tsa boemo ba kilowatt. S&Mochine o chesang ka ho fetisisa oa laser Letoto le ka fihlela litlhoko tsa ho pholisa tsa li-lasers tse ngata tse potlakileng 'marakeng, le ho ruisa S&A chiller sehlahisoa mola ho ea ka liphetoho marakeng.

E anngoe ke lintlha tse kang COVID-19 le tikoloho e sa tsitsang ea moruo, tlhoko ea lisebelisoa tsa elektroniki tsa bareki joalo ka lioache le matlapa e tla fokotseha ka 2022, mme tlhokahalo ea li-lasers tse potlakileng ho PCB (boto ea potoloho e hatisitsoeng), liphanele tsa ponts'o le LED e tla fokotseha. Ke masimo a selikalikoe le a chip feela a khannoang, 'me machining a ultrafast laser precision a bile le mathata a kholo.

Mokhoa oa ho tsoa bakeng sa li-lasers tsa ultrafast ke ho eketsa matla le ho nts'etsapele maemo a ts'ebeliso e eketsehileng. Li-picoseconds tsa Watt tse makholo li tla ba tse tloaelehileng nakong e tlang. Sekhahla se phahameng sa ho pheta-pheta le li-laser tsa matla a pulse matla li nolofalletsa bokhoni bo matla le ho feta ba ho sebetsa, joalo ka ho seha le ho cheka likhalase ho fihla ho 8 mm botenya. Laser ea picosecond ea UV ha e na khatello ea maikutlo ebile e loketse ho sebetsana le lisebelisoa tse nang le kutloelo-bohloko haholo, joalo ka li-stents tse sehang le lihlahisoa tse ling tsa bongaka tse hlokolosi haholo.

Kopanong le tlhahisong ea lihlahisoa tsa elektroniki, sebaka sa sefofane, biomedical, semiconductor wafer le liindasteri tse ling, ho tla ba le palo e kholo ea litlhoko tsa machining tse nepahetseng bakeng sa likarolo, mme ts'ebetso ea laser e sa amaneng le eona e tla ba khetho e ntle ka ho fetisisa. Ha maemo a moruo a phahama, ts'ebeliso ea li-lasers tsa ultrafast e tla khutlela tseleng ea kholo e phahameng.
