Itekhnoloji ye-Laser ye-Laser yeFiber

2.2 I-Wavelet enye inee-SIRTEumthombo we-laser

Ukufezekiswa kwe-Laser ye-Laser eyodwa ukutshayela ngokuyimfuneko ekulawuleni iipropathi zomzimba wesixhobo kwii-laserI-cavity (ihlala iphambili iZiko le-Bandwidth yeSebe eliSebenzayo), ukuze kufezekiswe ulawulo kunye nokukhethwa kwendlela ye-oscillaling ye-oscillaling kwi-caverinaling kwi-caveling, ukuze kufezekiswe injongo yokukhupha i-wavelength yemveliso. Ngokusekwe kulo mgaqo, kwasekuqaleni kweminyaka yoo-1980, ukufezekiswa kweefayili zefayibhakiswe ikakhulu ngokutshintsha ubuso obuphezulu, kwaye ukhetha indlela ye-Laser ye-Laser ngokujikeleza ngokutsha. Ngo-2011, zhu et al. I-Filters esetyenzisiweyo i-Filters yokufezekisa-i-wavelength ye-wavement yokuphumelela kwezasenzi kunye ne-tenew daywidth. Ngo-2016, indlela yeRaleyigh ye-rayywidth yoxinzelelo yafakwa kwimozulu ye-quial-wavenength, oko kukuthi, uxinzelelo lwalusetyenzisiwe kwi-FBG yokufezekisa i-FBG yokufikelela kwi-fuvement ye-fundle, kwaye i-Laser Linew yabekwa esweni kwi-3 NM. I-Doal-Wavehlelerg yezahlelayo ngobubanzi belayini malunga ne-700 hz. Ngo-2017, Zhu et al. Isetyenziswe iGraphene kunye ne-Micro-Nano ye-fiber fiber ye-filter ye-filter, kwaye idityaniswe ne-Brillouin Laser Techting ye-Traphene iphantsi ne-75 mhz / NM kwi-WMECH / NM. Njengoko kubonisiwe kumzobo 5. Indlela yokulawula i-wavenet yesaphulelo iyaqonda ukuba ukukhetha okanye ngokungathanga ngqo kutshintsha iziko le-PassibeBity yesixhobo kwi-laser sever.

2.3 Umthombo wokukhanya we-White Laser

Ukuphuhliswa komthombo weHight White unamava amanqanaba ahlukeneyo anjenge-halogn tungsten ye-tungsten yesibane, isibane seDeuterium,I-Semiconductor Laserkunye ne-supercontaum yokukhanya komthombo. Ngokukodwa, i-supercontnunuum yokukhanya komthombo, phantsi komculo we-phytosencond okanye i-pickocond enefuthe lee-odolo ezahlukeneyo, kwaye inokuthi igubungele i-bitting ye-wandred, kwaye inontlalontle. Ukongeza, ngokuhlengahlengisa ukusasazeka kunye nokungafani kwefayibha ekhethekileyo, imbonakalo yayo inokwandiswa kwibhendi ephakathi. Olu hlobo lomthombo lase-laser lusetyenziswe kakhulu kwiindawo ezininzi, ezinje nge-temography, ibrinte yokuchonga igesi, ingcinga yebhayoloji, njalo njalo. Ngenxa yokusikelwa komthombo wokukhanya okukhanyayo kunye ne-noline ye-nolinedar PrectRum Spectrum yaveliswa ikakhulu yiglasi ye-pumply ye-pumply pumps of pumical ivelise i-supercontrum kwindawo ebonakalayo. Ukusukela ngoko, ifayibha yefayili ngokuthe ngcembe iyeyona ndawo iphambili yokuvelisa i-SuperContnununugunugunugunuum ngenxa yendawo yayo enkulu engafakwanga kunye nendawo encinci yokuhambisa. Eyona nto iphambili kweziphumo eziziintloko zibandakanya ukuxutywa kwemine yokuxutywa, ukunqongophala kwendalo, ukunqongophala kwesigaba, i-soliton yokwahlula-hlula, i-raman yasasazwa, njl. Ngokubanzi, ngoku i-Supercontnunuum yokukhanya komthombo kukuphucula amandla e-laser kunye nokwandisa uluhlu olubonakalayo, kwaye unikele ingqalelo kulawulo lwalo lonyango.

3 Isishwankathelo

Eli phepha lishwankathela imithombo yase-laser esetyenziselwa ukuxhasa itekhnoloji yokufakelwa kwe-fiber, kubandakanya i-Laser ye-Wibser Toow, i-frequency ye-terwlity ye-grey kunye ne-groadball emhlophe. Iimfuno zesicelo kunye nenqanaba lokuphuhlisa kwezi zithambisi kwicandelo lefibre laziswa ngokweenkcukacha. Ngokuhlalutya iimfuno zabo kunye nenqanaba lophuhliso, kugqityiwe ukuba umthombo ofanelekileyo we-fiber firling unokufikelela kwinqanaba le-ultra emxinwa kunye ne-Ultra-izinzile nangaliphi na ixesha. Ke ngoko, siqala ngomgca omxinwa i-lar, i-tick inomgangatho wobubanzi be-laser kunye ne-White Laser ene-bandwidth ebanzi, kwaye ufumanise indlela esebenzayo yokufezekisa i-fiber ehlolisise uphuhliso lwefibre.
