Pankhani ya ma lasers amphamvu kwambiri, mipiringidzo ya laser ndizofunikira kwambiri. Sikuti amangokhala ngati magawo oyambira mphamvu zamagetsi, komanso amaphatikiza kulondola komanso kuphatikiza kwaukadaulo wamakono wa optoelectronic.-kuwapezera dzina lakutchulidwa: "injini" ya machitidwe a laser. Koma kodi kapangidwe ka laser bar ndi chiyani, ndipo imatulutsa bwanji ma watts makumi kapena mazana kuchokera ku mamilimita ochepa chabe kukula kwake? Nkhaniyi ikufotokoza za zomangamanga zamkati ndi zinsinsi zaukadaulo kuseri kwa mipiringidzo ya laser.
1. Kodi Laser Bar ndi Chiyani?
Laser bar ndi chipangizo champhamvu chotulutsa mphamvu chopangidwa ndi tchipisi tambiri ta laser diode zokonzedwa motsatira gawo limodzi. Ngakhale kuti mfundo yake yogwira ntchito ndi yofanana ndi ya laser single semiconductor, laser bar imagwiritsa ntchito mawonekedwe a multi-emitter kuti ikwaniritse mphamvu yapamwamba ya kuwala ndi mawonekedwe ophatikizika kwambiri.
Mipiringidzo ya laser imagwiritsidwa ntchito kwambiri m'mafakitale, azachipatala, asayansi, ndi chitetezo, kaya ngati magwero achindunji a laser kapena magwero a pampu a ma lasers a fiber ndi ma laser-state olimba.
2. Mapangidwe Apangidwe a Laser Bar
Mapangidwe amkati a laser bar amatsimikizira momwe amagwirira ntchito. Kwenikweni ili ndi zigawo zikuluzikulu zotsatirazi:
①Emitters Array
Mipiringidzo ya laser nthawi zambiri imakhala ndi ma emitter 10 mpaka 100 (ma laser cavities) okonzedwa mbali ndi mbali. Aliyense emitter ndi pafupifupi 50-150μm m'lifupi ndipo imagwira ntchito ngati gawo lodziyimira pawokha, lokhala ndi mphambano ya PN, patsekeke yolumikizira, ndi mawonekedwe a waveguide kuti apange ndikutulutsa kuwala kwa laser. Ngakhale ma emitters onse amagawana gawo limodzi, nthawi zambiri amayendetsedwa ndi magetsi molingana kapena madera.
②Kapangidwe ka Semiconductor Layer
Pamtima pa laser bar pali mulu wa zigawo za semiconductor, kuphatikiza:
- P-mtundu ndi N-mtundu epitaxial zigawo (kupanga PN mphambano)
- Zosanjikiza zogwira ntchito (mwachitsanzo, kapangidwe ka chitsime cha quantum), zomwe zimatulutsa mpweya wolimbikitsa
- Waveguide wosanjikiza, kuwonetsetsa kuwongolera kwamayendedwe am'mbali ndi ofukula
- Zowunikira za Bragg kapena zokutira za HR / AR, zomwe zimawonjezera kutulutsa kwa laser
③Mapangidwe a Substrate ndi Thermal Management
Zotulutsa zimabzalidwa pa gawo lapansi la monolithic semiconductor (makamaka ma GaAs). Kuti muthe kutenthetsa bwino, bala ya laser imagulitsidwa pazitsulo zokhala ndi ma conductivity apamwamba monga mkuwa, aloyi ya W-Cu, kapena diamondi ya CVD, ndikuphatikizidwa ndi masinki otentha komanso makina oziziritsa omwe amagwira ntchito.
④Emission Surface ndi Collimation System
Chifukwa chakusiyana kwakukulu kwa matabwa otulutsidwa, mipiringidzo ya laser nthawi zambiri imakhala ndi ma lens ang'onoang'ono (FAC/SAC) kuti agwirizane ndi kupanga matabwa. Kwa mapulogalamu ena, ma optics owonjezera-monga ma cylindrical lens kapena prisms-amagwiritsidwa ntchito kuwongolera kusiyana kwakutali komanso mtundu wa mtengo.
3. Zinthu Zofunika Kwambiri Zomwe Zimakhudza Kachitidwe
Kapangidwe ka bar laser kamakhala ndi gawo lofunikira pakuzindikira kukhazikika kwake, kuchita bwino, komanso moyo wantchito. Zofunikira zingapo zikuphatikiza:
①Thermal Management Design
Mipiringidzo ya laser imakhala ndi mphamvu zambiri komanso kutentha kwakukulu. Kukana kwamafuta ochepa ndikofunikira, komwe kumatheka kudzera pa AuSn soldering kapena indium bonding, kuphatikiza ndi kuziziritsa kwa microchannel kwa kutentha kofananako.
②Kupanga kwa Beam ndi Kuyanjanitsa
Ma emitter angapo nthawi zambiri amavutika ndi kusalumikizana bwino komanso kusalongosoka pamafunde. Mapangidwe olondola a lens ndi kuyanjanitsa ndikofunikira kwambiri pakuwongolera bwino kwamitengo yakutali.
③Kuwongolera Kupsinjika ndi Kudalirika
Kusagwirizana kwazinthu m'magawo okulitsa matenthedwe kungayambitse kupotoza kapena ma microcracks. Zoyikapo ziyenera kupangidwa kuti zigawitse kupsinjika kwamakina molingana ndi kupirira panjinga yotentha popanda kuwonongeka.
4. Zochitika Zam'tsogolo mu Laser Bar Design
Pamene kufunikira kwa mphamvu zapamwamba, kukula kochepa, ndi kudalirika kwakukulu kukukula, mapangidwe a laser bar akupitiriza kusinthika. Njira zazikulu zopangira chitukuko ndi:
①Kukula kwa Wavelength: Kukula mpaka 1.5μm ndi magulu apakati a infrared
②Miniaturization: Kuthandizira kugwiritsa ntchito zida zophatikizika ndi ma module ophatikizika kwambiri
③Smart Packaging: Kuphatikizira masensa kutentha ndi machitidwe amayankhidwe
④High-Density Stacking: Zosanjikiza zosanjikiza kuti mukwaniritse ma kilowatt-level mulingo wophatikizika
5. Mapeto
Monga“mtima”yamagetsi amphamvu kwambiri a laser, kapangidwe kake ka mipiringidzo ya laser imakhudza mwachindunji mawonekedwe a kuwala, magetsi, ndi matenthedwe a dongosolo lonselo. Kuphatikiza ma emitters ambiri m'mapangidwe a millimeters m'lifupi sikungowonetsa zida zapamwamba komanso njira zopangira, komanso zimayimira kuphatikizika kwakukulu masiku ano.'s photonics industry.
Kuyang'ana m'tsogolo, pomwe kufunikira kwa magwero odalirika, odalirika a laser kukukulirakulira, zatsopano zamapangidwe a laser bar zikhalabe choyendetsa chachikulu pakupititsa patsogolo msika wa laser kupita kumalo atsopano.
Ngati inu'mukuyang'ananso chithandizo cha akatswiri pakuyika laser bar, kasamalidwe kamafuta, kapena kusankha kwazinthu, omasuka kulumikizana nafe. Ife'bwerani pano kuti mupereke mayankho ogwirizana kuti agwirizane ndi zomwe mukufuna.
