Mumunda weakakwira-simba lasers, laser mabara akakosha epakati zvikamu. Kwete chete ivo vanoshanda seyakakosha zvikamu zvekubuda kwesimba, asi ivo zvakare vanosanganisira iyo chaiyo uye kubatanidzwa kweazvino optoelectronic engineering.-vachivawanira zita remadunhurirwa: iyo "injini" yelaser masisitimu. Asi chii chaizvo chimiro chelaser bar, uye chinoburitsa sei makumi kana kunyange mazana emawatts ekubuda kubva kumamirimita mashoma muhukuru? Ichi chinyorwa chinoongorora zvemukati zvivakwa uye zvakavanzika zveinjiniya kuseri kwelaser bars.
1. Chii chinonzi Laser Bar?
Laser bar chishandiso chepamusoro-simba chinoburitsa chinoumbwa neakawanda laser diode machipisi akarongedzerwa pane imwe substrate. Nepo musimboti wayo wekushanda wakafanana neyeimwe semiconductor laser, iyo laser bar inoshandisa multi-emitter marongero kuti iwane yakakwirira yemaziso simba uye yakawanda compact fomu chinhu.
Mabhawa eLaser anoshandiswa zvakanyanya mumaindasitiri, ekurapa, esainzi, uye edziviriro zvikamu, ingave yakananga laser sosi kana sepombi masosi efiber lasers uye yakasimba-nyika lasers.
2. Kuumbwa Kwemaitiro eLaser Bar
Chimiro chemukati chelaser bar chinotarisa zvakananga kuita kwayo. Iyo inonyanya kuumbwa nezvinhu zvinotevera zvakakosha:
①Emitters Array
Mabhawa eLaser anowanzo sanganisira gumi kusvika zana emitters (laser cavities) akarongwa padivi nepadivi. Imwe neimwe emitter inosvika makumi mashanu-150μm yakafara uye inoita seyakazvimiririra kuwana dunhu, ine PN junction, resonant cavity, uye waveguide chimiro kugadzira uye kuburitsa laser mwenje. Nepo ese emitter achigovana imwe substrate, anowanzo fambiswa nemagetsi muparallel kana nenzvimbo.
②Semiconductor Layer Structure
Pamwoyo welaser bar pane stack ye semiconductor layer, kusanganisira:
- P-mhando uye N-mhando epitaxial layers (kuumba iyo PN junction)
- Active layer (semuenzaniso, quantum tsime dhizaini), iyo inogadzira inosimudzira kubuda
-Waveguide layer, kuve nechokwadi chekudzora modhi mune lateral uye yakatwasuka nzira
- Bragg inoratidzira kana HR / AR machira, ayo anosimudzira kuburitsa kwelaser
③Substrate uye Thermal Management Structure
Iwo emitter anokura pane monolithic semiconductor substrate (kazhinji maGaAs). Kuti inyatso kupisa kupisa, iyo laser bar inotengeswa pane yakakwirira-conductivity submounts senge mhangura, W-Cu alloy, kana CVD diamond, uye yakapetwa neanopisa anonyura uye anoshanda kutonhora masisitimu.
④Emission Surface uye Collimation System
Nekuda kwemakona mahombe ekusiyana kwematanda akaburitswa, mabara emalaser anowanzo kuve akashongedzerwa nemicro-lens arrays (FAC/SAC) yekudhumhana uye kuumbwa kwedanda. Kune mamwe maapplication, mamwe optics-semacylindrical lenzi kana maprism-anoshandiswa kudzora kure-kumunda divergence uye danda kunaka.
3. Zvinhu Zvikuru Zviitiko Zvinokurudzira Kuita
Chimiro chelaser bar chinoita basa rakakosha mukuona kugadzikana kwayo, kushanda zvakanaka, uye hupenyu hwesevhisi. Zvizhinji zvakakosha zvinhu zvinosanganisira:
①Thermal Management Dhizaini
Laser mabara anoratidza yakakwirira simba density uye concentrated kupisa. Kudzikira kwekushisa kwekudzivirira kwakakosha, kunowanikwa kuburikidza neAuSn soldering kana indium bonding, yakasanganiswa nemicrochannel kutonhora kweuniform kupisa kupisa.
②Beam Shaping uye Kurongeka
Mazhinji emitters anowanzo tambura nekusabatana kwakashata uye wavefront misalignment. Precision lens dhizaini uye kurongeka kwakakosha pakuvandudza kure-munda danda kunaka.
③Stress Control uye Kuvimbika
Kusapindirana kwezvinhu mumafuta ekuwedzera macoefficients anogona kutungamira kune warping kana microcracks. Packaging inofanirwa kugadzirwa kugovera mechanical stress zvakaenzana uye kushingirira kuchovha bhasikoro pasina kushatisa.
4. Future Trends muLaser Bar Design
Sezvo kudiwa kwesimba repamusoro, saizi diki, uye kuvimbika kukuru kuchikura, laser bar zvimiro zvinoramba zvichishanduka. Nzira huru dzekuvandudza dzinosanganisira:
①Wavelength Kuwedzera: Kuwedzera mu 1.5μm uye mabhendi epakati-infrared
②Miniaturization: Inogonesa kushandiswa mumakompakiti zvishandiso uye zvakanyanya kusanganiswa module
③Smart Packaging: Inobatanidza tembiricha sensors uye mamiriro emhinduro masisitimu
④Yakakwira-Density Stacking: Yakaiswa arrays kuti iwane kilowatt-level kubuda mune compact tsoka.
5. Mhedziso
Sezvo“mwoyo”yeakakwira-simba laser masisitimu, iyo dhizaini dhizaini yelaser bars inopesvedzera zvakananga iyo optical, yemagetsi, uye yekupisa kuita kwesese system. Kubatanidza akawanda emitters muchimiro angori mamirimita yakafara haingoratidzi emberi zvinhu uye matekiniki ekugadzira, asi zvakare inomiririra yakakwira mwero wekubatanidzwa nhasi.'s photonics industry.
Tichitarisa kumberi, sezvo kudiwa kweanoshanda, akavimbika laser masosi ari kuramba achikwira, hunyanzvi mune laser bar chimiro chicharamba chiri mutyairi akakosha mukusimudzira indasitiri yelaser kusvika pakakwirira.
Kana iwe'uri kutsvaga rutsigiro rwenyanzvi mulaser bar kurongedza, thermal management, kana sarudzo yechigadzirwa, inzwa wakasununguka kutibata. Isu're pano kuti upe mhinduro dzakarongedzerwa kuti dzienderane neyako chaiyo application zvaunoda.
