IdasanzweUltrafafari LaserIgice cya kabiri

Gutabira no gukwirakwira: gutinda kwitsinda
Imwe mu mbogamizi zo muri tekinike zigoye zahuye nigihe ukoresheje ultrafari ikomeje kuba ikomeje igihe cya ultra-ngufi-magufi yasohotse nalaser. Ultrafast malsos ntishobora kwibasirwa nigihe cyo kugoreka, bituma impinduramatwara igihe kirekire. Izi ngaruka ziragenda ziyongera uko igihe cya pulse ya mbere. Mugihe ulstrafafari lasers irashobora gusohora Pulse hamwe nigihe cyamasegonda 50, birashobora gushimangira mugihe ukoresheje indorerwamo na lens kugirango uhereze kuri pulse kumwanya wagenewe, cyangwa nohereza gusa umuvuduko binyuze mu kirere.

Iki gihe cyogorwa kimaze kuba gipimo cyitwa Itsinda ryatinze gutatanya (GDD), uzwi kandi nka kabiri-gahunda yo gutumiza. Mubyukuri, hariho kandi amagambo yo hejuru atandukanye ashobora kugira ingaruka kumafaranga yo gukwirakwiza ultrafart-laser Pulses, ariko mubikorwa, mubisanzwe birahagije kugirango usuzume ingaruka za GDD. Gdd ni agaciro-gutereka-gushingira kumurongo ugereranije nubwinshi bwibikoresho. Kohereza Optics nka lens, idirishya, hamwe nibigize akamaro mubisanzwe bifite indangagaciro nziza ya GDD, yerekana ko igihe kimaze guswera kimaze gutanga Opsic Igihe kirekire Igihe cyasohotse kuri abasohokaSisitemu ya Laser. Ibigize hamwe na frequence (ni ukuvuga, uburebure burebure) gukwirakwiza byihuse kuruta ibice hamwe ningingo zirenga (ni ukuvuga uburebure bugufi). Nkuko impingayinyura inyuze byinshi kandi byinshi, uburebure bwumuraba buzakomeza kwaguka kandi mugihe gito. Kubwato bugufi, bityo rero, bigatera amagegurira, iyi ngaruka irakabije kandi irashobora kuvamo igihe gikomeye cyo kugoreka.

ibiciro
Kuva ahisha amasoko ya Ultraface Laser, Spectroscopy yabaye imwe mubice byabo byingenzi. Mugukagabanya pulse igihe cyigihe cya femtosekond cyangwa atton Imwe mu nzira yingenzi ni icyerekezo cya kera, kandi kwitegereza icyerekezo cya atome cyateje imbere ibintu byingenzi nkibirori bya molecular, kunyeganyega kwa molekile, gusebanya kwa molekile hamwe no kwimurwa kwingufu muri poroteroythestic.

Peak-Power Ultrafafari Lasers ishyigikira inzira zidahwitse no kunoza imyanzuro yibinyabuzima byamashusho, nka microscopi nyinshi. Muri sisitemu ya photon, kugirango itange ikimenyetso kidahwitse kuva kumurima wibinyabuzima cyangwa fluorescent targent, fotografike ebyiri zigomba gukwirakwira mumwanya nigihe. Iyi nkomyi idahwitse itezimbere ibyemezo bigabanya cyane ibiganiro byubukorikori bwinyuma ibimenyetso byerekana ko icyorezo cya photon imwe. Amashuri yoroshye yerekanaga. Agace gato keza ka microscolan ya Multiphoton nayo irinda amafoto kandi igabanya ibyangiritse kurugero.

Gutunganya ibikoresho bya laser
Ultrafafari amoko alser kandi yahinduye laser larmachinings micromachinings micromImiste no gutunganya ibintu kubera uburyo budasanzwe umwuga ultrashort ukorana nibikoresho. Nkuko byavuzwe haruguru, mugihe muganira kuri LDT, igihe cyanyuma cyigihe cyihuta kuruta igihe gitandukanye cyo gukwirakwiza ubushyuhe muri kato yibikoresho. Ultrafafari lasers itanga ubushyuhe buto cyane-yibasiwe kurutaNanosecond Pulsers, bikaviramo igihombo cyo hasi no gushushanya neza. Iri hame rirakoreshwa mubisabwa mubuvuzi, aho kwiyongera kwabikeshejwe bya ultrafart-laser bifasha kugabanya ibyangiritse kubidukikije kandi biteza imbere uburambe bwo kubagwa mu gihe cya Laser.

ATTOSECond Pulses: Kazoza ka Ultrafafari
Nkuko ubushakashatsi bukomeje gutera imbere lasers ya Ulsers, urumuri rushya kandi rwinoze hamwe namakuru magufi magufi iratezwa imbere. Kugira ngo umuntu atsindire mu buryo bwihuse, abashakashatsi benshi bibanda ku gisekuru cya Attosecond Pulses - hafi 10-18 s muri ultraviolet ikabije - xuv) umurongo wa wavelet (xuv). ATTOSECond Pulses yemerera gukurikirana electron yo kugenda no kunoza gusobanukirwa imiterere ya elegitoroniki hamwe nubukanishi. Mugihe kwishyira hamwe kwa Xuv Attosecond Pozers mubikorwa byinganda bitaratera imbere, ubushakashatsi bukomeje no gutera imbere mu murima ndetse no gukora neza rwose muri pako ikora ikoranabuhangaAmasoko ya Laser.
