Ukusetyenziswa kwelaser yanamhlanje, umgangatho we-beam uye waba yenye yezona metrics zibalulekileyo zokuvavanya ukusebenza ngokubanzi kwelaser. Nokuba kunjalo'Ukusika ukuchaneka kwenqanaba le-micron kwimveliso okanye ukubonwa komgama omde kwi-laser ukusuka, umgangatho we-beam uhlala umisela impumelelo okanye ukungaphumeleli kwesicelo.
Ke, yintoni kanye kanye umgangatho webeam? Ichaphazela njani ukusebenza kwe-laser? Kwaye umntu unokukhetha njani umgangatho ofanelekileyo we-beam ukuhambelana neemfuno ezithile zesicelo?
1. Yintoni uMgangatho weBeam?
Ngamafutshane, umgangatho we-beam ubhekiselele kwiimpawu zokusasazwa kwendawo yomqadi welaser. Ichaza indlela umqadi onokugxila ngayo, ukuziphatha kwawo ukwahluka, kunye nendlela amandla awo asasazwa ngayo ngokufanayo.
Kwimeko efanelekileyo, umqa we-laser ufana nomqadi ogqibeleleyo weGaussian, obonisa eyona angle incinci yokwahlukana kunye nowona msebenzi ugxile kakhulu. Nangona kunjalo, ngenxa yezinto ezinje ngokwakhiwa komthombo, iipropathi zezinto eziphathekayo, kunye nefuthe lobushushu, imiqadi yelaser yehlabathi yokwenyani ihlala inengxaki yokusasazeka, ukugqwethwa, okanye ukuphazamiseka kwemultimode.-ngaloo ndlela kuncitshiswa umgangatho we-beam.
2. Iimpawu zoMgangatho weBeam eziqhelekileyo
①M² Into (iFactor yokusasaza kweBeam)
I-M² ixabiso yiparameter yokuqala esetyenziselwa ukuvavanya umgangatho we-beam.
M² = 1 ibonisa umqadi weGaussian ogqibeleleyo.
M² > I-1 ithetha ukuba umgangatho we-beam uthotywa, kwaye ukukwazi ukugxila kuya kuba nzima.
Kwizicelo zamashishini, uM² amaxabiso angaphantsi kwe-1.5 afuneka ngokubanzi, ngelixa iilaser zodidi lwesayensi zijolise kwi-M² amaxabiso asondele ku-1 kangangoko kunokwenzeka.
②Ukwahlukana kweBeam
Ukwahlukana kweBeam kuchaza ukuba ingakanani na i-laser beam eyandayo njengoko isasazeka kwimigama emide.
Ii-engile zokwahlukana ezincinci zithetha imiqadi egxininise ngakumbi, iindawo ezigxininisiweyo ezincinci, kunye nokuchaneka okukhulu kumgama omde.
③Iprofayili yeBeam kunye nokuhanjiswa kwamandla
Umqadi ophezulu kufuneka ube neprofayili ye-symmetric, i-uniform beam profile kunye neziko eliphezulu. Oku kuqinisekisa imveliso yamandla ecacileyo kunye nokulawulwayo ukusika, ukumakisha, kunye nezinye izicelo.
3. Indlela uMgangatho weBeam uchaphazela ngayo ii-Real-World Application
①ULungiselelo oluchanekileyo (Ukusika/Ukuwelda/ukuMakisha):
Umgangatho we-beam umisela ubungakanani bendawo ekugxilwe kuyo kunye noxinano lwamandla, okuchaphazela ukuchaneka komatshini kunye nokusebenza kakuhle.
②IiLaser zonyango:
Umgangatho we-Beam uchaphazela indlela amandla achanekileyo ahanjiswa ngayo kwiithishu kunye nendlela ukusasazwa kwe-thermal kulawulwa ngayo.
③Ubungakanani beLaser / LIDAR:
Umgangatho weBeam uchaphazela ngokuthe ngqo uluhlu lokubona kunye nesisombululo sendawo.
④Unxibelelwano lwaMacho:
Umgangatho weBeam uchaphazela ukucoceka kwemowudi yesiginali kunye nomthamo we-bandwidth.
⑤Uphando lwezeNzululwazi:
Umgangatho we-Beam uqinisekisa ukuhambelana kunye nokuzinza ekuphazamiseni okanye kwiimvavanyo ze-optical nonlinear.
4. Imiba ephambili echaphazela uMgangatho weBeam
①Uyilo loLwakhiwo lweLaser:
Iilaser ezikwimowudi enye zihlala zibonelela ngomgangatho ongcono womqadi kuneendlela ezininzi zelasesi.
②Zuza okuPhakathi kunye noYilo lweResonator:
Ezi zichaphazela ukuhanjiswa kwemodi kunye nokuzinza kwe-beam.
③Ulawulo lweMpembelelo yoThermal:
Ukutshatyalaliswa kobushushu obungalunganga kunokukhokelela kwi-lensing ye-thermal kunye nokuphazamiseka kwe-beam.
④Ukufana kweMpompo kunye noLwakhiwo lweWaveguide:
Ukumpompa okungalinganiyo okanye iziphene kulwakhiwo kunokubangela ukuthotywa kobume be-beam.
5. Indlela yokuphucula umgangatho weBeam
①Lungiselela uYilo lweSixhobo:
Sebenzisa izikhokelo zamaza ezikwimowudi enye kunye noyilo lweresonator elinganayo.
②Ulawulo lobushushu:
Dibanisa iisinki zobushushu ezisebenzayo okanye ukupholisa okusebenzayo ukunciphisa ukugqwetheka kwemitha okubangelwa kukufudumala.
③I-Beam-Shaving Optics:
Faka ii-collimators, izihluzi zendawo, okanye iziguquli zemowudi.
④Ulawulo lwedijithali & neNgxelo:
Sebenzisa ubhaqo lwangaphambili lwexesha lokwenyani kunye ne-adaptive optics ukufezekisa ulungiso oluguqukayo.
6. Isiphelo
Umgangatho weBeam ungaphezulu nje kwepharamitha ebonakalayo-it's i“ikhowudi echanekileyo”ye laser's ukusebenza.
Kwizicelo zehlabathi zokwenyani, umgangatho ophezulu we-beam unokuphucula kakhulu ukusebenza kakuhle, ukuchaneka, kunye nokuthembeka kweenkqubo zelaser. Kubasebenzisi abafuna ukusebenza okuphezulu kunye nokuhambelana, umgangatho we-beam kufuneka ube yingqwalasela ephambili xa ukhetha i-laser.
Njengoko itekhnoloji yelaser iqhubeka nokuvela, sinokulindela ulawulo olungcono lwemitha kwizixhobo ezincinci kunye nokuxinana kwamandla aphezulu-ukuvula indlela yamathuba amatsha kwimveliso ephezulu, iyeza elichanekileyo, i-aerospace, nangaphaya.
