Chitukuko ndi msika wa laser

Chitukuko ndi msika wa laser (gawo lachiwiri)

Mfundo Yogwira Ntchito yaChosavuta

Pali mfundo zitatu zothetsa kupeza ndalama zambiri. Ambirialars owoneka bwinoGwiritsani ntchito zinthu zogwirira ntchito ndi mizere yonse ya fluorescentcent. Otsutsa omwe amapanga laser ali ndi zotayika pang'ono pokha pamtundu wopapatiza. Chifukwa chake, woyamba ndi kusintha mutu wa laser posintha mawonekedwe ogwirizana ndi dera lochepa lokhala ndi zinthu zina (monga grating). Lachiwiri ndikusintha mphamvu ya kusintha kwa laser posintha magawo ena akunja (monga maginito, kutentha, ndi zina). Chachitatu ndikugwiritsa ntchito zotsatira zosagwirizana kuti mukwaniritse kusintha kwa Hightathth Malonda owoneka bwino a kukoka koyamba ndi utoto wa utoto, a Chrysoberyl Lasers, a Lasers Center, a Lasers okwera ma gasi ndi otanuka.

Yambitsani laser kuchokera ku malingaliro okwanira amagawika: Tekinoloje yolamulira yapano, kutentha kwaukadaulo wamagetsi ndi ukadaulo wolamulira wolamulira.
Pakati pawo, ukadaulo wamagetsi ndi kusintha kwamphamvu posintha jakisoni wa m'mandandanda wa NS-DRWidth, koma mphamvu yotulutsa magetsi, yowonjezera ma dbr (ochita malonda). Technology yoyang'anira ukadaulo imasintha mutu wa laser posintha mndandanda wa dera la laser. Tekinoloje ndi yosavuta, koma pang'onopang'ono, ndipo imatha kusinthidwa ndi mliri wopapatiza chabe wa nm. OGULITSIRA KWAMBIRI PAKUTI MABWINO OTHANDIZADfb laser. Kuwongolera makina kumakhazikitsidwa makamaka kwa ma memssic (ma micro-elekitiro-elector) kuti mumalize kusankha kwa Hunseth, wokhala ndi bandwidth yosinthika, mphamvu yotalikirana. Zolinga zazikulu zochokera muukadaulo wolamulira wamakina ndi DFB (zogawana) Izi zikufotokozedwa kuchokera pamalingaliro awa a angalangidwe.

Ntchito yolumikizirana

Laser yovomerezeka ndi chipangizo chamtundu wa optoectronic mu m'badwo watsopano wa ma celly ogawika pogawidwa ndi Photon kusinthana mu ma netiweki onse. Ntchito yake imawonjezera mphamvu, kusinthasintha ndi kusokonekera kwa mapangidwe omasulira a Purtel Fire, ndipo wazindikira mosalekeza kapena mosalekeza.
Makampani ndi mabungwe ofufuza padziko lonse lapansi akulimbikitsanso kafukufukuyu komanso kukulitsa kafukufukuyu wowoneka ngati anyani, ndipo kupita patsogolo kwatsopano kumapangidwa nthawi zonse mu gawo ili. Kuchita kwa a Lasers owoneka kumachitika nthawi zonse ndipo mtengo wake umachepetsedwa. Pakadali pano, a Lasers agawidwa makamaka m'magulu awiri: Semiconductork amawoneka a Lasers ndi ma lasers otayika.
Semiconductor laserNdi gwero loyenerera mu njira yoyeserera, yomwe ili ndi mawonekedwe ang'onoang'ono, olemera kwambiri, otembenuka kwambiri, opulumutsa mphamvu, ndi zina zambiri. Itha kugawidwa m'makona ogulitsa a Bracketiated
Kukula kwa thumba la chofunda monga momwe zimakhalira ndi semiconductork laser diode monga gwero la pomlo limalimbikitsa kwambiri chitukuko cha mafayilo. Chosakanidwa ndi 80nm chimalandira bandwidth wa fibeshi, ndipo kuyambiranso kwa fyuluta kumawonjezeredwa ndi chiuno kuti achotse malo okhala akuopsa ndikuzindikira.
Kukula kwa semiconducki yotakasuka kumakhala yogwira kwambiri padziko lapansi, ndipo kupita patsogolo kumachitikanso mwachangu. A Ma Lasers ooneka bwino kwambiri akuyandikira mafunde a Hulleng esers pamgwirizano ndi magwiridwe, amagwiritsidwa ntchito mopitilira m'makampani komanso njira yofunika kwambiri m'tsogolo.

Chiyembekezo cha chitukuko
Pali mitundu yambiri ya ma lasers owoneka bwino, omwe nthawi zambiri amapangidwa ndikuyambitsanso njira zobwezera zamphamvu zosiyanasiyana, ndipo zida zina zidaperekedwa pamsika padziko lonse lapansi. Kuphatikiza pa kukula kwa mapiri othamanga owoneka bwino, ma lasers omwe amaphatikizidwa ndi ntchito zina zalembedwa, ndipo lasekani lation yolumikizidwa ndi ma syprator owoneka bwino ndi mayamwidwe osakhalitsa.
Chifukwa chakuti laserleththyated laser limagwiritsidwa ntchito kwambiri, loser yotakatayitsika ya nyumba zosiyanasiyana imatha kugwiritsa ntchito machitidwe osiyanasiyana, ndipo aliyense ali ndi zabwino ndi zovuta. Kunja kwa kunja kwa semiconductor ya laser itha kugwiritsidwa ntchito ngati gwero lalitali poyeserera poyeserera molondola chifukwa cha mphamvu zake zazikulu komanso mphamvu zowoneka bwino. Kuchokera ku mawonekedwe a Photon ndikukumana ndi maukonde onse owoneka bwino, kubzala zitsanzo, otchuka a DBR ndi zokongoletsera ndi ma aesers ophatikizidwa ndi ma modlars omwe amaphatikizidwa ndi magwero owoneka bwino a Z.
Fibha imatayatsidwa laseji yokhala ndi khomo lakunja ndikulonjezanso mtundu wa mawu owunikira, omwe ali ndi mawonekedwe osavuta, mulifupi wamfupi komanso mawonekedwe osavuta fiber. Ngati a EA osintha akhoza kuphatikizidwa mu dengalo, itha kugwiritsidwanso ntchito ngati mawonekedwe othamanga othamanga othamanga solon. Kuphatikiza apo, ma lasers otayika otayika otengera ma lasers aphiri adapita patsogolo kwambiri m'zaka zaposachedwa. Titha kuyembekezeredwa kuti ma alangizi a ma alars othana ndi malingaliro azovuta adzatukuka, ndipo gawo lamasika lidzakula pang'onopang'ono, ndi chiyembekezo chowala kwambiri.
