I-Marlow Linewidth Laser Technology Ingxenye Yesibili

(3)I-SOLL SOLLOWO STATE LASER

Ngo-1960, i-ruby laser yokuqala ye-ruby yayiyi-laser eqinile yombuso, ebonakala ngamandla aphezulu okuphuma kanye ne-wavelth ebanzi. Isakhiwo sendawo esiyingqayizivele se-solid-State Laser siyenza iguqulwe ngokwengeziwe ekwakhiweni komphumela omncane we-linewidth. Njengamanje, izindlela eziphambili ezisetshenzisiwe zifaka indlela emfushane ye-cavity, indlela eyodwa ye-ring cavity, indlela ejwayelekile ye-intracavity, indlela ye-torsion pendulum mode, indlela yokulinganisa imbewu.

Umdwebo 7 ukhombisa ukwakheka kwama-lasers ama-lases asezingeni elithile ahlala elokuqala.

Umdwebo 7 (a) ukhombisa umgomo osebenzayo wokukhethwa kwemodi eyodwa endeitudinal ngokusekelwe ku-In-Cavity FP Standard, okungukuthi, ukuhanjiswa okuningana okuhambisanayo kwe-LEADIDTH, ukuze amanye amaModi amade ehleliwe enqubweni yokuncintisana emincane ngenxa yokudluliselwa kwemodi emincane ngenxa yokudluliselwa kwemodi emincane. Ngaphezu kwalokho, uhla oluthile lomphumela we-wavenweth lungatholwa ngokulawula i-angle kanye lokushisa kwe-FP Standard kanye nokushintsha isikhawu semodi ende. Fig. I-7 (B) no (c) ikhombise i-oscillator engahleli ye-Oscillator (NPRO) kanye ne-Torsional Pendulum Mode Experty isetshenziselwa ukuthola okukodwa okukhipha imodi ende. Umgomo wokusebenza ukwenza ugongolo lukhuphuke ngendlela eyodwa ku-resonator, ukuqeda ngokuphumelelayo ukusatshalaliswa kwenombolo okungekho emgodini okubuyiselwe emgodini ojwayelekile wokuma, futhi ngenxa yalokho gwema ithonya lomphumela wemodi ye-Spatial Hole. Isisekelo sokukhethwa kwemodi ye-Bulk Bragg (VBG) sifana naleso se-semiconductor kanye ne-fiber eliphansi elibanzi le-lasers elishiwo ekuqaleni, okususelwa ku-vbg ukukhethwa kwalo okuningana, njengoba kukhonjiswe kuMdwebo oqondile, njengoba kukhonjisiwe kuMfanekiso 7 (d).
Ngasikhathi sinye, izindlela ezimbalwa zokukhethwa kweModi ye-Longitudinal zingahlanganiswa ngokuya ngezidingo zokuthuthukisa ukunemba kokukhethwa kweModigudinal Mode, noma kukhulise amandla okuncintisana we-laser ngenkathi usebenza emugqeni omncane, okunzima ukukwenzaI-Semiconductor Laserna-I-Fibre Lasers.

(4) I-Brillouin Laser

I-Brillouin Laser isuselwa ekusakazeni okuvuselelwa kwe-Brillouin (SBS) ukuthola umsindo ophansi, ubuchwepheshe obuncane bokukhipha umugqa, ukuxhumeka kwalo bangaphakathi kwe-acoustic field ukukhiqizwa okujwayelekile kwama-tushen ama-photons, futhi kuthuthukiswa ngokuqhubekayo ngaphakathi kwe-bandwidth yokuthola inzuzo.

Umdwebo 8 ukhombisa umdwebo weleveli yokuguqulwa kwe-SBS kanye nokwakheka okuyisisekelo kwe-brillouin laser.

Ngenxa yemvamisa ephansi yokudlidliza yensimu ye-acoustic, ukushintshwa imvamisa ye-brillouin of okuqukethwe kuvame ukuba ngu-0,12 Ngaphezu kwalokho, ngoba i-Brillouin Getwidwidth ye-Medium imvamisa kuphela kwe-MHZ-GHZ (i-Brillouin Getwidwidth yemidiya ethile eqinile, ingaphansi kwe-Brillouin Laser kuphela, i-Brillouin Laser kuphela, i-Brillouin Laser ingakhombisa into ebonakalayo evuthayo ngemuva I-cavity, futhi ububanzi bawo bomugqa bawo buyimiyalo eminingana yobubanzi obuncane kunomugqa wepompo. Njengamanje, i-Brillouin laser isiphenduke i-hotspot ecwaningayo enkambisweni ye-Photonics, futhi kube nemibiko eminingi nge-Order ye-Hz ne-Sub-HZ ye-LINGWIDTH umphumela omkhulu kakhulu.

Eminyakeni yamuva nje, amadivaysi e-Brillouin anesakhiwo se-waveguide aqhamuke emkhakheni weizithombe ze-microwave pemonics, futhi bathuthuka ngokushesha lapho kuqondiswa okuncane, ukuhlanganiswa okuphezulu nesinqumo esiphakeme. Ngaphezu kwalokho, i-Space-Runnil Brillouin Laser esuselwa kwizinto ezintsha ze-crystal ezinjengedayimane nayo ifake umbono wabantu eminyakeni emibili edlule, amandla e-Brillouin SBS ku-10 W ubukhulu, babeka isisekelo sokwandisa uhlelo lwayo.

Ngokuhlola okuqhubekayo kolwazi lokusika, ama-lasers angenamikhawulo e-linewidth asephenduke ithuluzi elisemqoka ocwaningweni lwesayensi ngokusebenza kwawo okuhle kakhulu, njenge-laser interferometer limbid ukutholwa kwe-travitational wave ukutholwa kokutholwa kwe-gravitational wavei-laserNge-wavelength ka-1064 nm njengomthombo wembewu, kanye ne-linewidth yokukhanya kwembewu kungakapheli ama-5 KHZ. Ngaphezu kwalokho, ama-lasers amancane abanzi ane-wavewthfung auble futhi akukho mbumbulu ephindaphindeka futhi abonise amandla aphezulu okusebenza, ikakhulukazi ezokuxhumana, futhi kulindeleke ukuthi kube yithuluzi eliyisisekelo lesizukulwane esilandelayo sobuchwepheshe bezokuxhumana ngeselula.
Esikhathini esizayo, okusha kwezinto ze-laser kanye nobuchwepheshe bokucubungula kuzothuthukisa ukucindezelwa kweLaser Linewidth, ukuthuthukiswa kokuqina kwe-wavency, ukwanda kwe-wavelength ranges kanye nokwenza ngcono amandla okuhlola komuntu ongaziwa.
