Sezvo yakakwirira-simba laser zvikumbiro zvichiramba zvichikura, mabhawa elaser diode ave akakosha munzvimbo dzakadai sekupomba laser, kugadzirisa maindasitiri, michina yekurapa, uye tsvakiridzo yesainzi. Nesimba ravo rakanaka resimba, modular scalability, uye yakakwirira electro-optical kunyatsoita, izvi zvishandiso zviri papakati peakawanda emazuva ano laser system. Zvakadaro pakati peakawanda ekuita zviratidzo zvelaser diode bar, imwe paramende inowanzo furatirwa asi yakakosha zvakanyanya: iyo divergence angle. Ichi chinyorwa chinoongorora hunhu, mavambo emuviri, uye zvinorehwa neiyo divergence angle mumalaser diode mabara-uye kuti dhizaini yemaziso inogona sei kuzvibata nemazvo.
1. Chii chinonzi Divergence angle?
Iyo divergence angle inotsanangura kuti danda re laser rinopararira sei sezvo richipararira munzvimbo yemahara. Inoratidza chiyero icho danda rinowedzera kubva kune emission facet. Mune laser diode mabara, iyo divergence angle inoratidza yakasimba asymmetry mumativi maviri makuru:
Fast Axis: Perpendicular kune iyo bar pamusoro. Nzvimbo yekuburitsa yakatetepa zvakanyanya (kazhinji 1–2 µm), zvichitungamira kumakona makuru ekusiyana, kazhinji 30°–45° kana kupfuura.
Slow Axis: Parallel kusvika kureba kwebhari. Nharaunda yekuburitsa yakapamhama (mazana emamicrons), zvichikonzera makona madiki akasiyana, anowanzo kutenderera 5 ° -15 °.
Iyi asymmetric divergence idambudziko rakakura redhizaini yekubatanidza sisitimu inosanganisira laser diode mabara.
2. Mavambo Panyama Ekusiyana
Iyo divergence angle inonyanya kutsanangurwa neiyo waveguide chimiro uye emission facet saizi:
Mune axis inokurumidza, nzvimbo yekuburitsa idiki zvakanyanya. Zvinoenderana nedzidziso yediffraction, maburi madiki anokonzera kusiyana kukuru.
Mune inononoka axis, danda rinowedzera nekureba kwebhari kune akawanda emitters, zvichikonzera diki divergence angle.
Nekuda kweizvozvo, mabhawa e laser diode anoratidza mutsauko wakanyanya muiyo axis inokurumidza uye yakaderera divergence mune inononoka axis.
3. Sei Divergence Angle Inobata System Design
① Mutengo Wepamusoro weCollimation uye Beam Shaping
Nekuda kweasymmetry yakakwira yedanda mbishi, FAC (Fast Axis Collimation) uye SAC (Slow Axis Collimation) optics inofanirwa kushandiswa. Izvi zvinowedzera sisitimu kuoma uye zvinoda yakanyanya kuisirwa kurongeka uye kugadzikana kwemafuta.
② Yakakwana Fiber Coupling Efficiency
Kana uchibatanidza malaser mabara kuita multimode fiber, optical masisitimu, kana aspheric lenses, iyo yakakura inokurumidza-axis divergence inogona kutungamira kune danda "spillover," ichideredza kubatanidza kushanda zvakanaka. Divergence ndiyo tsime guru rekurasikirwa kwemaziso.
③ Beam Hunhu muModule Stacking
Muma-multi-bar akaturikidzana mamodule, kusarongeka kwakasiyana-siyana kunogona kukonzera kusaenzana kwedanda kupindirana kana kure-kumunda kukanganisa, zvichikanganisa kutarisa chaiko uye kugovera kwemafuta.
4. Nzira Yokudzora uye Kugadzirisa Divergence muLaser Diode Bars
Kunyangwe kusiyana kuchinyanya kutsanangurwa nechimiro chemudziyo, akati wandei-system-level mazano anogona kushandiswa kugadzirisa:
①Kushandiswa kweFAC Lenses
Kuisa inokurumidza-axis collimation lens padhuze neinomira facet inomanikidza danda uye inoderedza kupatsanura muakisi inokurumidza-izvi zvakakosha mumagadzirirwo mazhinji.
②SAC Lenses yeKuwedzera Maumbirwo
Kunyangwe iyo inononoka-axis divergence idiki, kuumbwa kuchiri kudikanwa mune arrays kana mutsara-mwenje masosi kuti uwane yunifomu kubuda.
③Beam Kubatanidza uye Optical Shaping Dhizaini
Kushandisa ma micro-lens arrays, cylindrical lens, kana akarongeka optics anogona kubatsira kuumba akawanda laser matanda kuita yakakwirira-kupenya, yunifomu kubuda.
④Mudziyo-Level Waveguide Optimization
Kugadzirisa iyo inoshanda dhizaini ukobvu, waveguide dhizaini, uye grating zvimiro zvinogona kuwedzera kunatsiridza kukurumidza-axis kusiyanisa kubva padanho rechip.
5. Divergence Control mune Real-World Applications
①Laser Pombi Sources
Mune yakakwirira-simba rakasimba-nyika kana fiber laser masisitimu, laser diode mabara anoshanda sepombi masosi. Kudzora mutsauko-kunyanya mu-axis inokurumidza-inovandudza kubatanidza kushanda zvakanaka uye kutarisa kwedanda.
②Mishonga Yezvokurapa
Kune masisitimu akaita selaser therapy uye kubviswa kwebvudzi, kutonga mutsauko kunovimbisa kuti yakawedzera yunifomu yesimba kuendesa uye yakachengeteka, inoshanda zvakanyanya kurapwa.
③Industrial Material Processing
Mune laser welding uye kucheka, optimized divergence inobatsira kune yakakwira simba density, kutarisisa zvirinani, uye kunyatsojeka, kunoshanda kugadzirisa.
6. Mhedziso
Iyo divergence angle yelaser diode bar inzvimbo yakakosha yekuchinja-kubva ku micro-scale chip fizikisi kuenda kune macro-scale optical masisitimu.
Iyo inoshanda seyese danda chiratidzo chemhando uye muganho wekugadzira wekubatanidza. Sezvo zvinodiwa zvekushandisa uye kuoma kwehurongwa kuri kuramba kuchikwira, kunzwisisa uye kudzora mutsauko kunova kugona kukuru kwevagadziri velaser uye vanobatanidza zvakafanana-kunyanya kufambira mberi kune simba repamusoro, kupenya, uye kuvimbika.
