Laser ndiyo chinhu chikuru chemichina yekugadzirisa laser, tekinoroji yelaser yave chinhu chakakosha chinokanganisa hunyanzvi hwemichina yekugadzirisa laser, laser yeChinese ultrafine yakasangana nedanho rekushandisa murabhoritari, nhanho yekushandiswa kwemaindasitiri madiki nepakati, ichapinda muchikamu chekushandiswa kwemaindasitiri makuru, nhanho yekutumira zvinhu muindasitiri uye chiyero chemusika chiri kukura nekukurumidza nekukura kweindasitiri. Mune ramangwana, zvinotarisirwa kuti saizi yemusika weindasitiri icharamba ichikura pasi pemutemo uyu.
Ruzivo rukuru rwepepa rino: huwandu hwemabhizinesi ari muindasitiri yelaser ye ultrafast, kutumirwa kwe ultrafast femtosecond ultrafast laser, saizi yemusika weindasitiri yelaser ye ultrafast, nezvimwewo. Ultrafast laser inoreva laser ine nguva pfupi yelaser pulse. Kana ichienzaniswa ne nanosecond laser, nguva ye ultrafast laser pulse ipfupi kwazvo, simba rekukurumidza rakakwirira kwazvo, simba rinotariswa kunzvimbo diki kwazvo uye harikanganiswi ne pulse repetition rate uye avhareji yesimba, hunhu hwe beam hwakagadzikana.
Kubva muna 1961, apo laser yekutanga yeruby yeChina yakagadzirwa neChangchun Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, tekinoroji yelaser yakafamba nekukurumidza kwekukura kwemakore anopfuura makumi mashanu. Panyaya yekukura kwemaindasitiri, kubvira kuma1990, makambani ekare elaser akatanga kugadzira laser ye ultra-short pulse. Mumakore achangopfuura, nekuvandudzika kuri kuramba kuchienderera mberi kwekugadzikana, laser yakatanga kushandiswa muindasitiri yakakura.
Panyaya yekudiwa kwemusika we ultrafast laser, zvichienderana nehuwandu hwe2021 China Laser Industry Development Report yakaburitswa pamwe chete neWuhan Literature and Information Center yeChinese Academy of Sciences, Chinese Laser Journal, Chinese Optical Society nedzimwe nzvimbo, kutumirwa kwe ultrafast femtosecond ultrafast laser muChina kwakawedzera gore negore kubva muna 2015 kusvika 2020, nekukura kweanopfuura 50%. Muna 2020, China yakatumira 2,100 femtosecond ultra-fast lasers, yakakwira ne52.2 muzana pagore.
Panyaya yehukuru hwemusika, zvichienderana nehuwandu hweWuhan Literature and Information Center of Chinese Academy of Sciences, huwandu hwekutengesa kwelaser yeChinese ultrafast hwakakura nekukurumidza kubva muna 2015 kusvika 2020. Muna 2020, huwandu hwekutengesa kwelaser yeChina ultrafast hwakapfuura mabhiriyoni 2.7 eyuan, nekukura kwegore negore kwe10.20%. Avhareji yekukura kwemusika welaser yeChinese kubva muna 2015 kusvika 2020 inenge 56.24%.
Laser ndiyo chinhu chikuru chemichina yekugadzira laser, uye hunyanzvi hwelaser hunova chinhu chikuru chinokanganisa hunyanzvi hwemichina yekugadzira laser. Iyo micro-machining laser icharamba ichiita kuti ienderane newavelength pfupi, pulse width yakamanikana uye simba rakakwirira, uye mamiriro ekushandisa micro-machining achawedzerwa. Chirongwa chemakore mashanu chegumi nemana cheNyika cheKubudirira kwehupfumi nemagariro evanhu pamwe neOutline ye2035 Vision Goals yePeople's Republic of China, chakaburitswa munaKurume 2021, chakakurudzirwa kukurudzira kugadzirisa uye kusanganisa masisitimu ekuvandudza anotungamirirwa nezvinodiwa zvehurongwa hwenyika, uye kukurumidzisa kuvaka masimba esainzi netekinoroji anotungamirirwa nema laboratories enyika. Ma laboratories mazhinji enyika achagadzirwa kuti atarise minda mikuru yekugadzira senge quantum information, photonics uye micro and nano electronics, uye ma laboratories epasi rose achagadziriswazve kuti aumbe sisitimu yerabhoritari ine chimiro chakanaka uye mashandiro anoshanda zvakanaka.
Zvichitungamirirwa nehurongwa hwesainzi hwekutanga uye kuwedzera kwekuda, kugona kwemusika we ultra-short pulse laser inomiririrwa ne picosecond ne femtosecond kucharamba kuchiwedzera. Nokudaro, zvinofungidzirwa kuti hukuru hwemusika weindasitiri ye ultrafast laser yeChina hucharamba huchikura neanenge 15%. Zvinofungidzirwa kuti hukuru hwemusika weindasitiri ye ultrafast laser yeChina huchasvika kuma yuan angangoita mabhiriyoni 6.2 muna 2026.
