Gabatar da "Rai" na lasers masu ƙarfi

Babban TasharLaser mai ƙarfikayan aiki

Tushen kowane laser shine sinadarin aiki na laser, kuma sinadarin aiki na yanayin solid-statelasera zahiri yana da ƙarfi. Yawancin hanyoyin laser masu ƙarfi suna ƙunshe da matrices na kristal da atoms masu doped ko ions tare da aikin laser, yayin da matrices marasa tsari (gilashi) ba su da yawa. Ana sa ran sabon ci gaba a fasahar shirya yumbu zai faɗaɗa fa'idar amfani da kayan laser masu rahusa da inganci, waɗanda za a iya yin su da girman da ya fi na kayan lu'ulu'u girma.

Core kayan Laser masu ƙarfi da ake amfani da su akai-akai

Ruby: Sinadarinsa na sinadarai shine aluminum oxide mai chromium (Cr:Al₂O₃). Ruby na wucin gadi yana da irin sinadaran da aka yi amfani da su wajen hada ruby ​​masu ingancin duwatsu masu daraja, amma suna da tsarki da inganci mafi girma. Suna kama da ruwan hoda kuma suna da tsawon laser na nanometer 694.3.

2. Garnet aluminum mai suna yttrium mai suna Neodymium (Nd:YAG): Lu'ulu'u na wucin gadi, mai tsawon laser na nanomita 1064, yana cikin hasken infrared kuma ba a iya gani ko kaɗan kuma ba shi da haɗari ga idanu. Nd:YAG shine kayan laser mai ƙarfi da aka fi amfani da shi a yanzu, wanda ya zarce ruby. Babban dalilin shine cewa iyakar laser ɗinsa ta yi ƙasa, kuma tana iya samun ƙarin kuzarin fitarwa a ƙarƙashin irin wannan kuzarin shigarwa.

3. yttrium vanadate mai suna Neodymium (Nd:YVO₄) Sau da yawa ana kiransa da "vanadate", ya zama abin da aka fi so don ƙarancin wutar lantarki zuwa matsakaici (har zuwa watts da yawa) na lasers masu ƙarfi na diode saboda babban ɓangaren watsawar da ke motsawa, ƙarancin matakin laser da halayen fitarwa na polarized. Tsawon raƙuman aiki sune nanometers 1064 da nanometers 1340, kuma bayan ninka mita sau biyu, yana iya fitar da lasers tare da tsawon nanometers 532 da nanometers 670.

4. Gilashin Neodymium mai kauri (Nd:Glass): Ta amfani da gilashin amorphous a matsayin matrix, halayen laser ɗinsa suna kama da na Nd:YAG. Babban rashin amfanin sa shine cewa ƙarfin zafin sa yana da ƙasa kaɗan, 1/10 kawai na lu'ulu'u, wanda hakan ke sa ya zama da wahala a sanyaya a aikace-aikacen da ke da ƙarfi sosai. Duk da haka, fa'idarsa ta ta'allaka ne da gaskiyar cewa ana iya yin sa a cikin hanyar laser mai diamita fiye da ƙafa ɗaya, yana sarrafa yawan kuzari yadda ya kamata, yana guje wa lalacewar abubuwan gani a matakin kilojoule.laser mai bugun jini, kuma yana da ƙarancin farashi.

Sauran muhimman kayan laser masu ƙarfi, kayan da aka yi da erbium: gami da erbium-doped yttrium aluminum garnet (Er:YAG, tsawon fitowar nanometers 2940) da kuma erbium-doped Glass (Er:Glass, tsawon fitowar nanometers 1540). Kayan da aka yi da Holmium doped: gami da holmium doped yttrium aluminum garnet (Ho:YAG), holmium doped lithium yttrium fluoride (Ho:YLF), da holmium doped Glass (Ho:gilashi, tsawon fitowar nanometers 2000 zuwa 2100). Kayan da aka yi da Thulium doped: gami da thulium-doped yttrium aluminum garnet (Tm:YAG), thulium-doped lutetium aluminum garnet (Tm:LuAG), da thulium-holmium co-doped lithium yttrium fluoride (Tm,Ho:YLF, tsawon fitowar nanometers 2000 zuwa 2030). Kayan da aka yi wa allurar Ytterbium: kamar su potassium gadolinium tungstate mai ytterbium (Yb:KGW, tsawon fitowar nanomita 1025 zuwa 1045). Alexandrite (tsawon fitowar nanomita 655 zuwa 815). Sapphire mai alkalami na titanium (Ti:Sapphire, tsawon fitowar nanomita 840 zuwa 1100)
