Remangwana re ultrafast precision machining

Precision machining chikamu chakakosha chekugadzira laser. Yakagadzira kubva pakutanga yakasimba nanosecond girini / ultraviolet lasers kune picosecond uye femtosecond lasers, uye ikozvino ultrafast lasers ndiyo inonyanya kukosha. Chii chichave chiri ramangwana rekusimudzira maitiro eiyo Ultrafast precision machining?

Ultrafast lasers vaive vekutanga kutevedzera solid-state laser tekinoroji nzira. Solid-state lasers ane hunhu hwepamusoro kubuda simba, kugadzikana kwepamusoro uye kutonga kwakanaka. Ndivo kuenderera mberi kwekusimudzira nanosecond/sub-nanosecond solid-state lasers, saka picosecond femtosecond solid-state lasers inotsiva nanoseconds solid-state lasers zvine musoro. Fiber lasers dzakakurumbira, ultrafast lasers dzakafambawo dzakananga kwainotungamira fiber lasers, uye picosecond/femtosecond fiber lasers akabuda nekukurumidza, achikwikwidza neakasimba ekupedzisira lasers.

Chinhu chakakosha cheiyo ultrafast lasers ndiko kukwidziridzwa kubva kune infrared kusvika kune ultraviolet. Infrared picosecond laser processing ine inenge yakakwana mhedzisiro mukucheka girazi uye kuchera, ceramic substrates, wafer kucheka, nezvimwe. Nekudaro, iyo ultraviolet mwenje pasi pechikomborero che-ultra-short pulses inogona kuwana "kutonhora kugadzirisa" kusvika kune yakanyanyisa, uye kurovera uye kucheka pane izvo zvinhu zvinenge zvisina scorch marks, kuita zvakakwana kugadzirisa.

Iyo tekinoroji yekuwedzera maitiro e-ultra-short pulse laser ndeyekuwedzera simba , kubva pa3 watts uye 5 watts mumazuva ekutanga kusvika ikozvino 100 watt level. Parizvino, kunyatsogadziriswa mumusika kunowanzo shandisa makumi maviri watts kusvika makumi mashanu watts emagetsi. Uye sangano reGermany rakatanga kugadzirisa dambudziko rekilowatt-level ultrafast lasers. S&A ultrafast laser chiller akatevedzana anogona kusangana nekutonhodza zvinodiwa zveakanyanya kukurumidza lasers pamusika, uye kupfumisa S&Chiller chigadzirwa mutsetse zvinoenderana nemusika shanduko.

Zvichikanganiswa nezvinhu zvakaita seCCIDID-19 uye mamiriro ehupfumi asina chokwadi, kudiwa kwemagetsi evatengi sewachi uye mahwendefa kuchave nehusimbe muna 2022, uye kudiwa kwema lasers ekupedzisira muPCB (akadhindwa bhodhi redunhu), mapaneru ekuratidzira uye LED zvichadzikira. Chete denderedzwa uye chip minda yakafambiswa, uye Ultrafast laser precision machining yakasangana nematambudziko ekukura.

Iyo nzira yekubuda kune Ultrafast lasers ndeyekuwedzera simba uye kukudziridza mamwe maficha ekushandisa. Mazana-watt picoseconds anozove akajairwa mune ramangwana. Yakakwira yekudzokorora mwero uye yakakwira pulse simba lasers inogonesa hukuru hwekugadzirisa masimba, sekucheka uye kudhirowa kwegirazi kusvika 8 mm gobvu. Iyo UV picosecond laser ine inenge isina kushushikana kwekupisa uye inokodzera kugadzirisa zvakanyanya kusimba zvinhu, sekucheka stents uye zvimwe zvinonyanya kunzwisiswa zvigadzirwa zvekurapa.

Mukugadzira zvigadzirwa zvemagetsi kusangana uye kugadzira, aerospace, biomedical, semiconductor wafer uye mamwe maindasitiri, pachave nenhamba huru yechaiyo machining zvinodiwa zvezvikamu, uye isiri-yekubata laser processing ichave yakanakisa sarudzo. Kana mamiriro ehupfumi atanga, kushandiswa kwema ultrafast lasers kunozodzokera kunzira yekukura kukuru.
