Isu lokwenza ngconoi-laser yesimo esiqinile
Ukuthuthukisa ama-laser e-solid-state kuhilela izici eziningana, futhi okulandelayo amanye amasu amakhulu okwenza ngcono:
一, Ukuma okuhle kakhulu kokukhethwa kwekristalu ye-laser: strip: indawo enkulu yokushabalalisa ukushisa, evumela ukuphathwa kokushisa. I-Fiber: isilinganiso esikhulu sendawo ebusweni kuya kuvolumu, ukusebenza kahle kokudlulisa ukushisa okuphezulu, kodwa naka amandla nokuqina kokufakwa kwe-fiber. Ishidi: Ubukhulu buncane, kodwa umphumela wamandla kufanele ucatshangelwe lapho ufaka. Induku eyindilinga: indawo yokushabalalisa ukushisa nayo inkulu, futhi ukucindezeleka komshini akuthinteki kakhulu. Ukuhlushwa kwe-Doping nama-ion: Lungiselela ukuhlushwa kwe-doping nama-ion ekristalu, ushintshe ngokuyisisekelo ukusebenza kahle kwe-crystal ekukhanyeni kwepompo, futhi unciphise ukulahleka kokushisa.
Futhi, imodi yokushabalalisa ukushisa yokuthuthukisa ukuphathwa kokushisa: ukupholisa uketshezi olucwilisiwe kanye nokupholisa igesi kuyizindlela ezivamile zokushabalalisa ukushisa, okudingeka zikhethwe ngokwesimo esithile sesicelo. Cabanga ngezinto zohlelo lokupholisa (njengethusi, i-aluminium, njll.) kanye nokuqhuba kwalo ukushisa ukuze kuthuthukiswe umphumela wokushabalalisa ukushisa. Ukulawula izinga lokushisa: Ukusetshenziswa kwama-thermostat kanye neminye imishini ukugcina i-laser endaweni yokushisa ezinzile ukuze kuncishiswe umthelela wokushintshashintsha kwezinga lokushisaukusebenza kwe-laser.
Ngaphezu kwalokho, Ukwenziwa ngcono kokukhethwa kwemodi yokupompa yemodi yokupompa: ipompo eseceleni, ipompo ye-engela, ipompo engaphezulu kanye nepompo yokugcina kuyizindlela ezivamile zokupompa. Ipompo yokugcina inezinzuzo zokusebenza kahle kokuhlanganisa okuphezulu, ukusebenza kahle kokuguqulwa okuphezulu kanye nemodi yokupholisa ephathekayo. Ukupompa eceleni kuyazuzisa ekukhuliseni amandla kanye nokufana kwe-beam. Ukupompa kwe-engela kuhlanganisa izinzuzo zokupompa ubuso kanye nokupompa eceleni. Ukugxila kwe-beam yepompo kanye nokusatshalaliswa kwamandla: Lungiselela ukugxila kanye nokusatshalaliswa kwamandla kwe-beam yepompo ukuze kwandiswe ukusebenza kahle kokupompa futhi kuncishiswe imiphumela yokushisa.
Ukwakheka okuhle kakhulu kwe-resonator ye-resonator kanye ne-output coupling: khetha ukubonakaliswa okufanele kwesibuko se-cavity kanye nobude be-cavity ukuze kufezwe umphumela we-multi-mode noma we-single-mode we-laser. Umphumela we-single longitudinal mode ubonakala ngokulungisa ubude be-cavity, futhi amandla kanye nekhwalithi ye-wavefront kuyathuthukiswa. Ukuthuthukiswa kokuhlanganiswa kokukhipha: Lungisa ukudluliselwa kanye nendawo yesibuko se-output coupling ukuze kufezwe umphumela osebenza kahle kakhulu we-i-laser.
Futhi, Ukulungiswa Kwezinto Nezinqubo Ukukhethwa Kwezinto: Ngokuya ngezidingo zohlelo lokusebenza lwe-laser ukukhetha izinto ezifanele zokuthola i-gain medium, njenge-Nd:YAG, Cr:Nd:YAG, njll. Izinto ezintsha ezifana ne-ceramics esobala zinezinzuzo zesikhathi esifushane sokulungiselela kanye nokusetshenziswa okulula kwe-doping ephezulu, okufanele ukunakwa. Inqubo yokukhiqiza: Ukusetshenziswa kwemishini yokucubungula enembile kakhulu kanye nobuchwepheshe ukuqinisekisa ukunemba kokucubungula kanye nokunemba kokuhlanganiswa kwezingxenye ze-laser. Umshini wokugaya nokuhlanganisa kahle kunganciphisa amaphutha nokulahlekelwa endleleni yokukhanya futhi kuthuthukise ukusebenza okuphelele kwe-laser.
I-六, Ukuhlolwa kokusebenza kanye nokuhlolwa Izinkomba zokuhlola ukusebenza: kufaka phakathi amandla e-laser, ubude be-wavelength, ikhwalithi yangaphambili yamagagasi, ikhwalithi yomsebe, ukuzinza, njll. Imishini yokuhlola: Ukusetshenziswaimitha yamandla e-optical, i-spectrometer, inzwa ye-wave front kanye neminye imishini yokuhlola ukusebenza kwe-laser. Ngokuhlola, izinkinga ze-laser zitholakala ngesikhathi futhi kuthathwa izinyathelo ezifanele ukuze kwenziwe ngcono ukusebenza.
Okunye, Ukuqamba okusha okuqhubekayo kanye nobuchwepheshe Ukulandelela ukusungula okusha kwezobuchwepheshe: naka izitayela zakamuva zobuchwepheshe kanye nezitayela zentuthuko emkhakheni we-laser, bese wethula ubuchwepheshe obusha, izinto ezintsha kanye nezinqubo ezintsha. Ukuthuthukiswa okuqhubekayo: Ukuthuthukiswa okuqhubekayo kanye nokusungula izinto ezintsha ngokwesisekelo esikhona, futhi uthuthukise njalo ukusebenza kanye nezinga lekhwalithi yama-laser.
Ngamafuphi, ukwenza ngcono ama-laser e-solid-state kudinga ukuqala ezicini eziningi, njenge-laser crystal, ukuphathwa kokushisa, imodi yokupompa, i-resonator kanye ne-output coupling, izinto zokwakha kanye nenqubo, kanye nokuhlolwa kokusebenza kanye nokuhlolwa. Ngezinqubomgomo eziphelele kanye nokuthuthukiswa okuqhubekayo, ukusebenza kanye nekhwalithi yama-laser e-solid-state kungathuthukiswa njalo.
