Indlela yokuthuthukisai-solid state lasers
Ukuthuthukisa ama-lasers wesifunda esiqinile kuhilela izici ezimbalwa, futhi okulandelayo ngamanye amasu okuthuthukisa:
1. Ukukhethwa kokuma okuhle kwekristalu ye-laser: i-strip: indawo enkulu yokulahla ukushisa, ehambisana nokuphathwa okushisayo. I-Fiber: indawo enkulu engaphezulu kuya kwesilinganiso sevolumu, ukusebenza kahle kokudlulisa ukushisa okuphezulu, kodwa naka amandla nokuqina kokufakwa kwe-fiber optical. Ishidi: Ubukhulu buncane, kodwa umphumela wamandla kufanele ucatshangelwe lapho ufaka. Induku ejikelezayo: indawo yokushisa ukushisa nayo inkulu, futhi ukucindezeleka komshini akuthinteki kancane. Ukugxiliswa kwe-Doping nama-ion: Lungiselela ukugxila kwe-doping nama-ion ekristalu, shintsha ngokuyisisekelo ukumuncwa nokusebenza kahle kokuguqulwa kwekristalu ibe ukukhanya kwephampu, futhi kunciphise ukulahlekelwa ukushisa.
2. Imodi yokukhipha ukushisa yokulawula ukushisa: ukupholisa uketshezi lokucwiliswa kanye nokupholisa igesi izindlela ezivamile zokulahla ukushisa, okudingeka zikhethwe ngokuya ngezimo ezithile zohlelo lokusebenza. Cabangela okokusebenza kwesistimu yokupholisa (okufana nethusi, i-aluminium, njll.) kanye ne-thermal conductivity yayo ukuze uthuthukise umphumela wokulahla ukushisa. Ukulawulwa kwezinga lokushisa: Ukusetshenziswa kwama-thermostat nezinye izinto zokusebenza ukugcina i-laser isendaweni yezinga lokushisa ezinzile ukuze kwehliswe umthelela wokushintshashintsha kwezinga lokushisa ekusebenzeni kwe-laser.
3. Ukwenziwa ngcono kokukhetha imodi yokupompa yemodi yokumpompa: ukupompa eceleni, ukupompa i-engela, ukupompa ubuso kanye nokumpompa kokugcina kuyizindlela ezijwayelekile zokupompa. Iphampu yokugcina inezinzuzo zokusebenza kahle kokuhlanganisa, ukuguqulwa okuphezulu kanye nemodi yokupholisa ephathekayo. Ukupompa eceleni kunenzuzo ekukhuliseni amandla kanye nokufana kwe-beam. Ukupompa i-engeli kuhlanganisa izinzuzo zokumpompa ubuso nokumpompa eceleni. Ukugxila kwe-Pump beam kanye nokusabalalisa amandla: Lungiselela ukugxila kanye nokusabalalisa amandla kwe-pump beam ukwandisa ukusebenza kahle kokumpompa nokunciphisa imiphumela eshisayo.
4. Idizayini ye-resonator ethuthukisiwe ye-resonator ehambisana nokuphumayo: khetha ukubonakala okufanele kanye nobude besibuko se-cavity ukuze uzuze ukuphuma kwemodi eminingi noma yemodi eyodwa ye-laser. Ukukhishwa kwemodi ye-longitudinal eyodwa kubonakala ngokulungisa ubude bomgodi, futhi amandla nekhwalithi yangaphambili yegagasi kuyathuthukiswa. Ukulungiselelwa kokuhlanganisa okukhiphayo: Lungisa ukudluliswa kanye nendawo yesibuko sokuhlanganisa okukhiphayo ukuze uzuze ukukhishwa okuphezulu kwe-laser.
5. Ukuthuthukiswa kwempahla nenqubo Ukukhetha kwezinto ezibonakalayo: Ngokwezidingo zokusetshenziswa kwe-laser ukukhetha impahla emaphakathi yokuzuza efanele, njenge-Nd:YAG, Cr:Nd:YAG, njll. Izinto ezintsha ezifana nezitsha zobumba ezibonisa ngale zinezinzuzo zokufushane. isikhathi sokulungiselela kanye ne-doping ephezulu yokuhlushwa kalula, okufanele ukunakwa. Inqubo yokukhiqiza: Ukusetshenziswa kwemishini yokucubungula ephezulu enembayo kanye nobuchwepheshe ukuze kuqinisekiswe ukunemba kokucubungula kanye nokunemba komhlangano wezingxenye ze-laser. Ukwenza kahle nokuhlanganisa kunganciphisa amaphutha nokulahlekelwa endleleni ye-optical futhi kuthuthukise ukusebenza okuphelele kwe-laser.
6. Ukuhlolwa kokusebenza nokuhlola izinkomba zokuhlola ukusebenza: okuhlanganisa amandla e-laser, ubude begagasi, ikhwalithi yangaphambili yegagasi, ikhwalithi ye-beam, ukuzinza, njll. Imishini yokuhlola: Sebenzisaimitha yamandla optical, i-spectrometer, inzwa yangaphambili yegagasi nezinye izisetshenziswa zokuhlola ukusebenza kwe-laser. Ngokuhlola, izinkinga ze-laser zitholakala ngesikhathi futhi izinyathelo ezihambisanayo ziyathathwa ukuze kuthuthukiswe ukusebenza.
7. Ukuqamba okusha okuqhubekayo kanye nobuchwepheshe Ukulandelela ukuqanjwa kabusha kwezobuchwepheshe: naka izitayela zakamuva zobuchwepheshe kanye nentuthuko emkhakheni we-laser, futhi wethule ubuchwepheshe obusha, izinto ezintsha nezinqubo ezintsha. Ukuthuthukiswa okuqhubekayo: Ukuthuthukiswa okuqhubekayo kanye nokuqanjwa okusha kusisekelo esikhona, futhi kuthuthukisa njalo ukusebenza kanye nezinga lekhwalithi lama-lasers.
Kafushane, ukuthuthukiswa kwama-lasers wesifunda esiqinile kudinga ukuqala ezicini eziningi, njengeikristalu laser, ukuphathwa kwe-thermal, imodi yokumpompa, i-resonator nokuhlanganisa okuphumayo, izinto ezibonakalayo nenqubo, nokuhlolwa kokusebenza nokuhlola. Ngezinqubomgomo ezibanzi kanye nokwenza ngcono okuqhubekayo, ukusebenza kanye nekhwalithi yama-lasers wesifunda esiqinile kungathuthukiswa ngokuqhubekayo.
