Laser ine zvinhu zvina zvikuru, zvinoti kupenya kwepamusoro, kutungamira kwakanaka, monochromaticity yakanaka, uye kubatana kwepamusoro.Izvi zvivakwa zvine hukama kune mumwe nemumwe, zvichiita kuti laser ive yakakodzera kune akasiyana mamiriro.
Kupenya kwepamusoro kwelaser chinhu chakakosha chakasiyana kubva kune akajairwa mwenje masosi, uye kuwedzera simba uye kupenya zvakare inyaya isingaperi yekuvandudza lasers.Chii chiri kupenya kwepamusoro, kunoratidzwa mumutauro wehunyanzvi ndechekuti iri padyo ne1 ndiyo index M2 inotsanangura kunaka kwedanda.
Mumakore achangopfuura, nekuvandudzwa kwetekinoroji, epamba faibha lasers zvishoma nezvishoma akatyora muganho wesimba, kubva pa12KW kusvika 20KW.Parizvino, iyo yepamusoro fiber laser ine simba re30KW yakatangwa pamusika, uye nhanho inotevera i50KW.Wese munhu anoteerera uye anokwikwidza kune ane laser yekubuda simba rakakwirira, asi anofuratira uyo ane nani beam mhando.
Nhasi ngatitarisei kuti chii chiri kupenya kwepamusoro, uye zvakanakira uye kukosha kwekupenya kwepamusoro.
Zvimiro zvelaser beam
Iyo laser mwenje inoburitswa nelaser inotaridzika seizvi, kutanga ichitenderera mumunda wepedyo, uye yozopararira mumunda uri kure.
mukati,
The beam waist radius w0 ndiyo radius iyo laser beam inochinjika kune diki chikamu mumunda wepedyo;
Iyo Rayleigh kureba ZR ndiyo nzvimbo apo chiuno chedanda chinowedzerwa ne √2 nguva;
Munda uri kure unotsanangurwa sehuwandu hunopfuura 4 nguva yeRayleigh kureba, uye munda uri pedyo unotsanangurwa sehuwandu mukati me4 nguva yeRayleigh kureba;
Iyo yekure-munda divergence angle θ inomiririra dhigirii rekusiyana kweiyo laser beam mumunda uri kure.
Hunhu hweBeam Quality
Beam mhando ndiyo yakakosha paramende kuratidza hunhu hwelaser beam, uye chiratidzo chakakosha che laser, iyo inoshandiswa kuyera dhigirii rekutarisa kwelaser beam mune chaiyo mamiriro.Nzira dzinowanzo shandiswa kuyera kunaka kwebeam ndeidzi: danda parameter chigadzirwa (BPP) uye M2factor.
BPP (Beam Parameter Chigadzirwa): danda parameter chigadzirwa, chinotsanangurwa sedanda rechiuno chiuno radius (w0) yakapetwa neiyo far-field divergence angle (θ):
M2: Chiyero cheiyo dhizaini paramende chigadzirwa kune danda paramende chigadzirwa cheiyo yakakosha Gaussian danda, inogona kushandurwa kuita BPP:
Kubva pane fomula iri pamusoro, tinogona kuwana zviri nyore kuti: BPP haina chekuita newavelength, nepo iyo M2 chinhu chine hukama nelaser wavelength.
Kukosha kweM² factor kusingagumi pedyo ne1, zvinoreva chiyero che data chaiyo kune data yakakodzera.Kana iyo chaiyo data iri padyo neiyo yakakodzera data, iyo beam mhando iri nani.
Kune fiber laser ine wavelength ye1070nm, iwo akakodzera paramita anofanirwa kunge ari:
Kana iyo fiber Laser BPP kana M2parameteriri padyo neukoshi uhwu, kunaka kwedanda kuri nani uye iyo inowirirana divergence angle idiki.
Nzira yekuziva sei danda remhando
Kazhinji, isu tinoshandisa danda analyzer kuyera danda remhando yelaser, rega analyzer ifambe inoenderana neiyo nzira yekuona, uye kuunganidza X, Y, uye Z ruzivo panzvimbo dzakawanda kuona danda rechiuno saizi, chinzvimbo, uye divergence angle. , uye kuverenga Rayleigh kureba uye BPP kana M2.
Inowanzo shandiswa nzira yebanga-kumucheto uye nzira yekutsemura.Mazano ezviviri izvi akafanana, kureva kuti, shandisa banga-mupendero kana kutsemura kutarisisa danda, kuyera uye mepu kugoverwa kwechiedza chechikamu, uye wobva wafamba kumusoro nekudzika kuyera uye mepu yenzvimbo yemwenje pa. madaro akasiyana.Pakupedzisira, matatu-dimensional light field distribution inowanikwa.
▲ nzira yebanga-kumucheto
▲ Slit nzira
Muedzo wemhando yebeam kazhinji wakaoma.Zviri nyore, isu tinogona kufungidzira fungidziro zvinoenderana nefiber core dhayamita uye manhamba aperture (NA).
Chiedza chechiedza, zvisinei kuti yakakura sei kona yemakona, inogona kutapurirana zvakajairika kana ichipinda mufiber mukati meiyo yakakosha chiitiko angle range.Sine kukosha kwekona iyi α ndiyo nhamba yekuvhura NA yefiber, kureva, NA=sinα, iyo inoratidza chiedza chinogamuchirwa nefiber.kugona.Zvinogona kutariswa zvakaenzana izvo.
Chii chatinowanzoreva nepamusoro-kupenya lasers?
Kupenya (Br) Tsanangudzo: Kuwanda kwesimba pachikamu chechikamu uye unit solid angle.Sezvatakambotaura, iyo yakakosha nzvimbo ye fiber laser
, nzvimbo iri kure-yakasimba kona
.
Zvinoenderana neformula iri pamusoro, hazvina kuoma kuona kuti iyo inonzi kupenya kwepamusoro zvinoreva kuti ine mhando yepamusoro yedanda (kureva, diki BPP kana M.2 ) pasi pesimba rimwechete.
Semutungamiri wepasi rose mune yakakwirira-kupenya lasers,GW Laser Tech inotarisa pakutsvagisa nekusimudzira kwe976nm yakakwirira-kupenya fiber lasers, inotungamira maitiro ekusimudzira efiber lasers.
Guanghui Laserari ega-nzira 10μmmuganhu faibha kubuda laser, M2<1.1, uye 50kw 100μm faibha laser vane simba density pedyo nemuviri muganhu.
Yakajairika 100μm yakakosha dhayamita imwe-modhi 4kW laser M2<1.3, akawanda-modhi 12kW laser BPP <4.
▲ Guanghui laser YLPS akatevedzana single module 4KW laser

Kukosha uye zvakanakira kupenya kwepamusoro
Mumakore achangopfuura, epamusoro-simba lasers ari kuita zvishoma nezvishoma simba guru mumusika, uye fiber lasers iri kufambawo kune yakakwirira simba.12KW lasers yave yakajairwa gadziriso ye mainstream laser vagadziri.Gore rakapera, Guanghui Laser kutengesa kwe20KW lasers kwakawedzera zvakanyanya;parizvino, 40KW lasers ari kutanga zvishoma nezvishoma kutumira.
Mazhinji emazuva ano epamusoro-simba fiber lasers anoumbwa nemamodule akawanda, kureva kuti, chiedza chinobuda neakawanda laser modules chinosanganiswa kuita imwe optical fiber yekubuda.Kuenzaniswa neinobuda fiber musimboti weimwe laser module, akawanda mamodule Iyo yakasanganiswa yekubuda fiber core dhayamita yakakura uye danda remhando yakaderera.
Kana iyo mhando yedanda ikafuratirwa, zvisinei kuti simba racho rakakwirira sei, rinogona kuitika kuburikidza neakawanda-module danda rekubatanidza chirongwa.Nekudaro, nekufambira mberi kwetekinoroji uye kukwidziridzwa kwemaindasitiri, iyo indasitiri yekugadzira ichaenda zvishoma nezvishoma yakananga kumagumo, izvo zvinozoisa pamberi pepamusoro uye zvakakwirira zvinodiwa zve lasers, kwete kungogutsa kuwedzera kwesimba, asi zvakare kutarisisa zvakanyanya kuvandudzwa kwekupenya. .Iwo epamusoro-simba lasers anongowedzera simba pasina kuterera kupenya achakurumidza kubviswa nemusika.
Kubva pakuvambwa kwayo, GW Laser Techyakazvipira kutsvagurudzo nekuvandudza kwepamusoro-kupenya lasers, uye ichawedzera simba uye kuwedzera kupenya zvakaenzana.Kuburikidza nekugadzirisa kweimwe laser module tekinoroji, fiber fusion splicing, uye danda kusanganisa zvirongwa, kupenya kwelaser kwakawedzera kuvandudzwa.Pasi pemamiriro emagetsi mamwechete, mushure mekudhumhana uye kutarisisa neiyo yakafanana optical system, nzvimbo iri panzvimbo idiki uye simba remagetsi rinokwira.Izvi zvinoratidzwa zvakananga mumashandisi ekugadzirisa laser: pasi pesimba rimwechete, kukurumidza kwekugadzirisa kunokurumidza;pasi pekumhanya kwakafanana kwekugadzirisa, simba rinodiwa idiki.
Tora GW Laser's YLPM akatevedzana 20KW laser yekucheka semuenzaniso.Kuenzaniswa nemamwe lasers pasimba rimwe chete, kumhanya kwekucheka kunokurumidza, uye mukana uyu unonyanya kuoneka mukucheka zvinhu zvinoratidzira zvakakwirira.
High-kupenya lasers igwara rakakosha rekusimudzira indasitiri yelaser.Ikozvino yakakwirira-simba laser musika yakaratidza pachena homogeneity, uye makuru ekugadzira laser ari kufambira mberi munzira yesimba rakanyanya.
GWLaserhaina hanya chete nekuwedzera kwesimba relaser, asi zvakare inobhadhara zvakanyanya kune kuvandudzwa kwekupenya kwelaser.Mune ramangwana, isu ticharamba tichiongorora munzira yekupenya kwakanyanya, kuitira kuti laser ive nani danda remhando uye mashandiro ekugadzirisa, uye inobatsira vatengi kuvandudza mashandiro ekugadzirisa.
