Kwintsimi yee-lasers ezinamandla aphezulu, imivalo ye-laser zizinto eziphambili eziyimfuneko. Ayisebenzi nje kuphela njengeeyunithi ezisisiseko zemveliso yamandla, kodwa ikwabandakanya ukuchaneka kunye nokudityaniswa kobunjineli banamhlanje be-optoelectronic.-ukubafumana igama lesiqhulo: "injini" yeenkqubo zelaser. Kodwa yintoni kanye kanye ubume belaser bar, kwaye iwahambisa njani amashumi okanye amakhulu eewatts zemveliso ukusuka kwiimilimitha nje ezimbalwa ngobukhulu? Eli nqaku liphonononga ulwakhiwo lwangaphakathi kunye neemfihlo zobunjineli emva kwemivalo yelaser.
1. Yintoni iBar yeLaser?
I-laser bar sisixhobo esikhupha amandla aphezulu esakhiwe ngeetshiphusi ezininzi ze-laser diode ezicwangciswe ecaleni kwi-substrate enye. Nangona umgaqo wayo wokusebenza ufana ne-laser ye-semiconductor enye, i-laser bar isebenzisa i-multi-emitter layout ukufezekisa amandla aphezulu optical kunye ne-compact form factor.
Imivalo yeLaser isetyenziswa ngokubanzi kuwo wonke amacandelo emizi-mveliso, ezonyango, ezenzululwazi, kunye nokhuselo, njengemithombo yelaser ethe ngqo okanye njengemithombo yempompo yeelaser zefiber kunye ne-solid-state lasers.
2. Ukwakheka koLwakhiwo lweBar yeLaser
Isakhiwo sangaphakathi se-laser bar sinquma ngokuthe ngqo ukusebenza kwayo. Ibandakanya ikakhulu la macandelo alandelayo:
①Emitters Array
Imivalo yeLaser idla ngokuba ne-10 ukuya kwi-100 emitters (imingxuma yelaser) ecwangciswe ecaleni. I-emitter nganye imalunga nama-50-150μm ububanzi kwaye isebenza njengommandla wokuzuza ozimeleyo, oquka isiphambuka se-PN, i-resonant cavity, kunye nesakhiwo se-waveguide ukuvelisa kunye nokukhupha ukukhanya kwe-laser. Ngelixa zonke ii-emitters zabelana nge-substrate efanayo, zihlala ziqhutywa ngombane ngokuhambelanayo okanye ngezowuni.
②Ulwakhiwo loMaleko weSemiconductor
Embindini webar ye-laser kukho inqwaba yeeleya ze-semiconductor, kubandakanya:
- Uhlobo lwe-P kunye nohlobo lwe-N-uhlobo lwe-epitaxial layers (ukwenza i-PN junction)
- Umaleko osebenzayo (umzekelo, ubume bequla le-quantum), ovelisa ukukhutshwa okuvuselelweyo
-I-Waveguide layer, iqinisekisa ulawulo lwemowudi kwicala elisecaleni kunye nelithe nkqo
-Izibonakalisi zeBragg okanye i-HR / AR yokwambathisa, ephucula isiphumo se-laser
③I-Substrate kunye ne-Thermal Management Structure
I-emitters ikhuliswe kwi-monolithic semiconductor substrate (ngokuqhelekileyo i-GaAs). Ukutshatyalaliswa kobushushu ngokufanelekileyo, i-laser bar ithengiswa kwi-high-conductivity submounts ezifana ne-copper, i-W-Cu ingxubevange, okanye i-diamond ye-CVD, kwaye idibaniswe kunye neesinki zokushisa kunye neenkqubo zokupholisa ezisebenzayo.
④I-Emission Surface kunye ne-Collimation System
Ngenxa yokwahlukana okukhulu kwee-engile zemiqadi ekhutshiweyo, imivalo yelaser idla ngokuxhotyiswa ngoluhlu lweelensi ezincinci (FAC/SAC) zokudityaniswa kunye nokubunjwa kwemiqadi. Kwizicelo ezithile, ii-optics ezongezelelweyo-njengeelensi zecylindrical okanye iiprism-zisetyenziselwa ukulawula ukuhlukana kwebala elikude kunye nomgangatho we-beam.
3. Imiba engundoqo yoLwakhiwo enefuthe kwiNtsebenzo
Ubume be-laser bar budlala indima ebalulekileyo ekumiseleni uzinzo, ukusebenza kakuhle, kunye nobomi benkonzo. Imiba ephambili emininzi ibandakanya:
①Uyilo loLawulo lweThermal
Imivalo yeLaser ibonisa ukuxinana kwamandla aphezulu kunye nobushushu obugxininisiweyo. Ukumelana ne-thermal ephantsi kubalulekile, kuphunyezwe nge-AuSn soldering okanye i-indium bonding, idityaniswe nokupholisa i-microchannel yokutshatyalaliswa kobushushu obufanayo.
②Ukubunjwa kweBeam kunye noLungelelwaniso
Ii-emitters ezininzi zihlala zinengxaki yokungahambelani kakuhle kunye nokungahambi kakuhle komphambili wamaza. Uyilo lwelensi oluchanekileyo kunye nokulungelelaniswa kubalulekile ekuphuculeni umgangatho we-beam ekude.
③Ulawulo loxinzelelo kunye nokuthembeka
Ukungahambelani kwezinto kwii-coefficients zokwandiswa kwe-thermal kunokukhokelela kwi-warping okanye i-microcracks. Ukupakishwa kufuneka kuyilwe ukuhambisa uxinzelelo lomatshini ngokulinganayo kunye nokumelana nokuhamba ngebhayisikile eshushu ngaphandle kokuthotywa.
4. IiNdlela zekamva kuYilo lweBha yeLaser
Njengoko imfuno yamandla aphezulu, ubungakanani obuncinci, kunye nokuthembeka okukhulu kukhula, izakhiwo ze-laser bar ziyaqhubeka nokuvela. Izalathiso ezingundoqo zophuhliso ziquka:
①Ukwandiswa kweWavelength: Ukwandiswa kwi-1.5μm kunye neebhendi eziphakathi kwe-infrared
②I-Miniaturization: Ukuvumela ukusetyenziswa kwezixhobo ezidibeneyo kunye neemodyuli ezidityanisiweyo kakhulu
③I-Smart Packaging: Ukubandakanya izinzwa zobushushu kunye neenkqubo zempendulo yesimo
④Ukupakishwa koXinano oluPhezulu: Uluhlu olucwangcisiweyo ukufikelela kwimveliso yenqanaba le-kilowatt kwindawo ehlangeneyo.
5. Isiphelo
Njenge“intliziyo”yeenkqubo zelaser ezinamandla aphezulu, uyilo lwesakhiwo semivalo yelaser ichaphazela ngokuthe ngqo ukusebenza kwe-optical, umbane, kunye ne-thermal yenkqubo iyonke. Ukudibanisa uninzi lwee-emitters kwisakhiwo nje i-millimeters ububanzi ayibonisi nje izinto eziphambili kunye nobuchule bokwenza, kodwa ikwamele inqanaba eliphezulu lokudityaniswa namhlanje.'s imboni yeefoto.
Ukujonga phambili, njengoko imfuno yemithombo ye-laser esebenzayo, ethembekileyo iqhubeka nokunyuka, izinto ezintsha kwisakhiwo se-laser bar ziya kuhlala zingumqhubi ophambili ekuqhubeleni phambili ishishini le-laser ukuya kwiindawo eziphakamileyo.
Ukuba u'ukukhangela kwakhona inkxaso yeengcali kwi-laser bar yokupakisha, ulawulo lwe-thermal, okanye ukhetho lwemveliso, zive ukhululekile ukuqhagamshelana nathi. Thina're apha ukunika izisombululo ezilungiselelwe ukuhambelana neemfuno zakho zesicelo.
