Ukusebenza okuphezulu kwe-Ultrafast wafer laser technology

Ukusebenza okuphezulu kwe-Ultrafast waferubuchwepheshe be-laser
Amandla aphezuluI-Ultrafast LasersIsetshenziswa kabanzi ekukhiqizeni okuthuthukile, imininingwane, ama-microelectonics, i-biomedicine, izivikelo zikazwelonke nasezempi nasezempi, futhi ucwaningo lwesayensi olufanele lubalulekile ukukhuthaza ubuchwepheshe bezesayensi kazwelonke nobuchwepheshe kanye nokuthuthuka okuphezulu. Isilayidi esincanyanaUhlelo lwe-LaserNgezinzuzo zayo zamandla aphezulu aphezulu, amandla amakhulu ama-pulse kanye nekhwalithi enhle kakhulu enesidingo esikhulu ku-physics ye-atosecond, ukucutshungulwa kwezinto ezibonakalayo nakwezinye izinkambu zezimboni, futhi kukhathazeke kabanzi amazwe omhlaba wonke.
Muva nje, iqembu labacwaningi eChina lisebenzise imodyuli ye-wafer eyakheke ngokwakho kanye nokuthola amandla okusebenza kabusha ukuze kufinyelelwe ukusebenza okuphezulu (ukuqina okuphezulu, amandla aphezulu, ikhwalithi ephezulu, ikhwalithi ephezulu)i-laserokuphumayo. Ngomklamo we-regeneration amplifier cavity kanye nokulawulwa kokushisa komhlaba kanye nokuqina kwemishini ye-disc crystal emgodini, 300 μj, futhi amandla aphezulu okuguqulwa okulula afinyelela ku-61%, okubuye kube yilapho kuguqulwa kahle kakhulu. I-Beam Quality Factor M2 <1.06@150w, 8h ukuqina kwe-RMS <0.33%, lokhu kufinyelelwa kuphawula inqubekela phambili ebalulekile ekusebenzeni okuphezulu kwe-ultrafast wafer laser, okuzohlinzeka ngamathuba amaningi we-Ultrafast Laser application.

Imvamisa ephezulu yokuphindaphinda, uhlelo oluphakeme lwamandla we-wafer regeneration amplification amplification amplification
Ukwakheka kwe-Wafer Laser Amplifier kukhonjiswa kuMfanekiso 1. Kubandakanya umthombo wembewu we-fiber, inhloko ye-laser ye-waser emncane kanye ne-amplifier revenerative amplifier. I-yterterbium-doped fiber oscillator enamandla aphakathi we-15 mW, i-wavelength ephakathi ne-1030 NM, ububanzi be-pulse buka-7.1 PS kanye nenani eliphindaphindwayo le-30 MHZ lalisetshenziswa njengomthombo wembewu. Inhloko ye-Waser Laser isebenzisa i-yb eyenziwe ekhaya Umthombo wepampu usebenzisa umugqa we-zero-phonon ld nge-969 NM yokukhiya i-wavelth, enciphisa isici se-quantum ku-5.8%. Isakhiwo esipholisa esiyingqayizivele singapholisa ngempumelelo i-Crystal ye-Wafer futhi siqinisekise ukuqina kobuso bokuvuselelwa kabusha. I-cavity evuselelwa kabusha iqukethe ama-pockers cell cell (PC), ama-polarizers amafilimu amancanyana (TFP), i-quarter-wave amapuleti (QWP) kanye nomthengisi onamandla wokuqina. Ama-Isolators asetshenziselwa ukuvimbela ukukhanya okukhulisiwe kusuka emuva - kulimaza umthombo wembewu. Isakhiwo se-Isolator esiqukethe i-TFP1, i-Rotator kanye namapuleti we-Half-wave (HWP) asetshenziselwa ukuhlukanisa imbewu yokufaka kanye nama-pulses akhulisayo. I-Pulse yembewu ingena egumbini lokuvuselelwa kabusha kwe-Amplification nge-TFP2. Ama-crystals we-barium metaboature (BBO), i-PC, ne-QWP Hlanganisa ukwakha i-Optical switch esebenzisa i-voltage ephezulu ngezikhathi ezithile kwi-PC ukuze iphinde ithumbe i-PULLE yembewu futhi ikhiphe emgodini. I-pulse efiselekayo ye-oscillates emgodini futhi iyanda ngempumelelo ngesikhathi sokusakazwa okusayindile ukusakazwa kahle isikhathi sokucindezela kwebhokisi.
I-Amplifier ye-Wafer Regeneration ikhombisa ukusebenza okuhle kokukhipha futhi izodlala indima ebalulekile kwizinkambu zokukhiqiza ezisezingeni eliphakeme njenge-Ultraviolet Lithography, umthombo wepompo we-atosecond, nezimoto ezintsha zamandla, kanye nezimoto ezintsha zamandla. Ngasikhathi sinye, kulindeleke ukuthi ubuchwepheshe be-laser laser ye-wafer kulindeleke ukuthi busetshenziswe kumandla amakhulu amakhuluAmadivayisi we-Laser, ukuhlinzeka ngezindlela ezintsha zokuhlola zokwakheka nokutholwa okuhle kwendaba esikalini se-nanoscale space kanye nesilinganiso sesikhathi se-femtosecond. Ngomgomo wokusebenzela izidingo ezinkulu zezwe, iqembu leprojekthi lizoqhubeka nokugxila emisha e-Laser Technology, futhi lithuthukise amandla okucwaninga ngamasu ama-Laser amadivaysi e-laser emikhakheni yolwazi, amandla, imishini ephezulu njalonjalo.
