(3)Leta ikomeye

Mu 1960, Ruby ya mbere yisi yabaye laser-leta, irangwa ningufu zirenze umusaruro mwinshi hamwe nimbaraga zagutse. Imiterere idasanzwe ya leta-leta ya laser irahinduka cyane muburyo bwo gushushanya umurongo muto. Kugeza ubu, uburyo nyamukuru bwashyizwe mu bikorwa hashyizweho uburyo buke bwo gutwara inkumi, uburyo bumwe bwo kuvura imyuka, guhinduranya uburyo bwa torisilum uburyo bwo gufata imyuka, uburyo bwo gufata bragg uburyo bwo gutera inshinge.

Igishushanyo 7 cyerekana imiterere yuburyo busanzwe-burebure bwa minitudinal-lasers.

Igishushanyo 7 (a) cyerekana ihame ryakazi ryuburyo bumwe bwo gutoranya dushingiye ku gipimo cya FP. Mubyongeyeho, urutonde runaka rwuburebure busarura rushobora kuboneka mugucunga inguni nubushyuhe bwa FP isanzwe kandi ihindura uburyo bwa burebire. Igishushanyo 7. Ihame ryakazi ni ugukwirakwiza beam apambana umwe muri renator, ukuraho neza ikwirakwizwa ryumubare uhagaze mumyanya isanzwe, bityo wirinde ingaruka zumubiri usanzwe uhagaze kugirango ugere kumiterere imwe yo gutwika. Ihame rya Bragg Bragg (VBG) Guhitamo Mode bisa nibijyanye na semiconductor na fibre ntoya kumurongo wavuzwe haruguru, ni ukuvuga gukoresha VBL, ukoresheje VBG mu buryo bwo kuyungurura ibintu bisanzwe, nkuko bigaragara ku gishushanyo cya 7 (D).
Mugihe kimwe, uburyo bwinshi bwo gutoranya uburyo bwo gutoranya burashobora guhuzwa hakurikijwe uburyo bwo guhitamo neza amakuru, cyangwa kwagura ibisohoka muburyo bwa laser mugihe gikora mu gusangantego, bigoye gukoraSemiconductor Laserkandifibre lasers.

(4) lallouin laser

Crillouin Laser ishingiye ku ngaruka zatewe na Brillouin (SBS) kugirango ibone urusaku ruto, ihame ridasobanutse, ihame ryo mu murima ndetse no mu rwego rwo gukora imiyoboro y'imbere mu mibonano mpuzabitsina, kandi ridakomeza koroshya imitsi.

Igishushanyo 8 cyerekana igishushanyo cyurwego rwa SBS gihinduka hamwe nuburyo bwibanze bwa lallouin laser.

Bitewe na vibire nkeya zo mu murima wa acouscy, guhinduranya imiyoboro ya trillouin muri rusange 0.1-25, ku birori byo guhindura abantu benshi, ariko ibi birasobanura kandi ko bikabije bingana na kamera ari hejuru cyane (kugeza 99.99% mu nyigisho). Byongeye kandi, kubera ko Brillouin yunguka igishushanyo mbonera mubisanzwe ni itegeko rya MHZ-GHZ (ntabwo ari munsi yumurongo wibitangazamakuru bya laser bikunze kwerekana ibintu bitangaje nyuma yinyongera Kwongegura mu cyuho, hamwe n'umurongo wacyo uringaniza ni amategeko menshi y'ubunini bunini kuruta ubugari bwa pompe. Kugeza ubu, Lallouin Laser yabaye hotspot yubushakashatsi muri Fhootics, kandi habaye raporo nyinshi kuri gahunda ya HZ na Sub-HZ yoroheje cyane.

Mu myaka yashize, ibikoresho bya Brillouin bifite imiterere ya Waveguide byagaragaye murwego rwaMicrowave Photonics, kandi utezimbere vuba mu cyerekezo cya miniaturogetion, kwishyira hamwe no gukemura byinshi. Byongeye kandi, umwanya-ukoresha larlouin laser ishingiye ku bikoresho bishya bya kirisiti nko mu iyerekwa ryabantu mu myaka ibiri ishize, intera ya Crillouin yakozwe mu myaka ibiri ishize, imbaraga za laser of the groser, zishyiraho umusingi wo kwagura ibisabwa.
Ihuriro rusange
Hamwe nubushakashatsi bukomeza guca ubumenyi, laserth onrowdth yagabanijwe mu bushakashatsi bwa siyansi n'imikorere yabo ikomeye, nka laser interferometero ya siyansi, ikoresha itara ryiza, rikoresha umurongo umwe mutolaserHamwe n'uburebure bwa 1064 nm nk'isoko y'imbuto, naho itabazwa ry'imbuto z'imbuto ziri muri 5 KHz. Byongeye kandi, ubugari-bugufi-budth hamwe nu murongo urabagirana kandi ntaburyo bwo gusimbuka kandi byerekana ubushobozi buke, cyane cyane muburyo bwuzuye bwo kugabana amakuru yuburebure (FDM) kugirango ugabanye ibishoboka byose, kandi biteganijwe ko rifite ibikoresho byingenzi byikoranabuhanga rizaza.
Mu bihe biri imbere, guhanga udushya twa laser no gutunganya ibicuruzwa bizakomeza guteza imbere compresseth ya laser canWidth, iterambere ry'imikorere idahwitse, kwaguka kw'imikorere no guteza imbere uburebure, guha imbaraga uburyo bwo gushakisha abantu isi itazwi.
