Ikon faɗin bugun jini nasarrafa bugun jini na laserfasaha
Sarrafa bugun jini na laser yana ɗaya daga cikin mahimman hanyoyin haɗi a cikinfasahar laser, wanda ke shafar aiki da tasirin amfani da laser kai tsaye. Wannan takarda za ta tsara tsarin sarrafa faɗin bugun jini, sarrafa mitar bugun jini da fasahar daidaitawa mai alaƙa, kuma ta yi ƙoƙari ta zama ƙwararru, cikakke kuma mai ma'ana.
1. Ra'ayin faɗin bugun jini
Faɗin bugun jini na laser yana nufin tsawon lokacin bugun jini na laser, wanda shine maɓalli mai mahimmanci don bayyana halayen lokacin fitowar laser. Ga lasers masu gajeren bugun jini (kamar nanosecond, picosecond da femtosecond lasers), gajeriyar faɗin bugun jini, mafi girman ƙarfin kololuwa, da kuma ƙaramin tasirin zafi, wanda ya dace da injinan daidaitacce ko binciken kimiyya.
2. Abubuwan da ke shafar faɗin bugun laser Faɗin bugun laser yana shafar abubuwa da yawa, galibi waɗanda suka haɗa da waɗannan fannoni:
a. Halaye na matsakaicin riba. Nau'o'in kafofin watsa labarai daban-daban suna da tsarin matakin makamashi na musamman da tsawon rayuwar haske, wanda ke shafar samarwa da faɗin bugun laser kai tsaye. Misali, lasers mai ƙarfi, lu'ulu'u na Nd:YAG da lu'ulu'u na Ti:Sapphire sune hanyoyin watsa labarai na laser mai ƙarfi na yau da kullun. Lasers na iskar gas, kamar lasers na carbon dioxide (CO₂) da lasers na helium-neon (HeNe), yawanci suna samar da bugun jini mai tsayi saboda tsarin kwayoyin halittarsu da halayen yanayin da aka motsa; Lasers na Semiconductor, ta hanyar sarrafa lokacin sake haɗa mai ɗaukar kaya, na iya cimma faɗin bugun jini daga nanoseconds zuwa picoseconds.
Tsarin ramin laser yana da tasiri mai mahimmanci akan faɗin bugun jini, gami da: tsawon ramin, tsawon ramin laser yana ƙayyade lokacin da haske ke tafiya akai-akai a cikin ramin, rami mai tsayi zai haifar da faɗin bugun jini mai tsawo, yayin da rami mai gajere yana da amfani ga samar da bugun jini mai gajere; Nunin Haske: Mai nunin haske mai haske mai yawa zai iya ƙara yawan photon a cikin ramin, ta haka yana inganta tasirin riba, amma hasken da ya yi yawa zai iya ƙara asarar a cikin ramin kuma ya shafi kwanciyar hankali na faɗin bugun jini; Matsayin matsakaicin riba da matsayin matsakaicin riba a cikin ramin suma zasu shafi lokacin hulɗa tsakanin photon da matsakaicin riba, sannan su shafi faɗin bugun jini.
c. Fasahar sauya yanayin Q da fasahar kulle yanayin hanya sune muhimman hanyoyi guda biyu don cimma fitowar laser na bugun jini da kuma daidaita fadin bugun jini.
d. Tushen famfo da yanayin famfo Daidaiton wutar lantarki na tushen famfo da zaɓin yanayin famfo suma suna da tasiri mai mahimmanci akan faɗin bugun jini.
3. Hanyoyin sarrafa faɗin bugun jini na yau da kullun
a. Canza yanayin aiki na laser: yanayin aiki na laser zai shafi faɗin bugunsa kai tsaye. Ana iya sarrafa faɗin bugun ta hanyar daidaita sigogi masu zuwa: mita da ƙarfin tushen famfo, shigar da kuzarin tushen famfo, da matakin juyewar yawan ƙwayoyin cuta a cikin matsakaicin riba; Hasken ruwan tabarau na fitarwa yana canza ingancin amsawa a cikin resonator, don haka yana shafar tsarin samuwar bugun jini.
b. Sarrafa siffar bugun zuciya: daidaita faɗin bugun zuciya ta hanyar canza siffar bugun laser.
c. Daidaitawar halin yanzu: Ta hanyar canza wutar lantarki ta hanyar fitar da wutar lantarki don daidaita rarrabawar matakan makamashin lantarki a cikin hanyar laser, sannan a canza faɗin bugun jini. Wannan hanyar tana da saurin amsawa mai sauri kuma ta dace da yanayin aikace-aikacen da ke buƙatar daidaitawa cikin sauri.
d. Sauya yanayin sauyawa: ta hanyar sarrafa yanayin sauyawa na laser don daidaita faɗin bugun jini.
e. Kula da zafin jiki: canje-canjen zafin jiki zai shafi tsarin matakin makamashin lantarki na laser, ta haka yana shafar faɗin bugun jini kai tsaye.
f. Yi amfani da fasahar daidaitawa: Fasaha daidaitawa hanya ce mai inganci ta sarrafa faɗin bugun jini daidai.
Daidaitawar LaserFasaha wata fasaha ce da ke amfani da laser a matsayin mai ɗaukar bayanai kuma tana loda bayanai a kai. Dangane da alaƙar da laser ɗin, za a iya raba shi zuwa tsarin daidaitawa na ciki da tsarin daidaitawa na waje. Tsarin daidaitawa na ciki yana nufin yanayin daidaitawa inda ake loda siginar da aka daidaita a cikin tsarin juyawar laser don canza sigogin juyawar laser don haka canza halayen fitarwa na laser. Tsarin daidaitawa na waje yana nufin yanayin daidaitawa inda ake ƙara siginar sauyawa bayan an samar da laser, kuma ana canza halayen fitarwa na laser ba tare da canza sigogin juyawa na laser ba.
Ana iya rarraba fasahar daidaitawa bisa ga siffofin daidaitawar mai ɗauka, gami da daidaitawar analog, daidaitawar bugun jini, daidaitawar dijital (daidaitaccen lambar bugun jini); Dangane da sigogin daidaitawa, an raba shi zuwa daidaitawar ƙarfi da daidaitawar lokaci.
Mai daidaita ƙarfi: Ana sarrafa faɗin bugun jini ta hanyar daidaita canjin ƙarfin hasken laser.
Mai daidaita lokaci: Ana daidaita faɗin bugun jini ta hanyar canza yanayin raƙuman haske.
Amplifier mai kulle lokaci: Ta hanyar daidaita amplifier mai kulle lokaci, ana iya daidaita faɗin bugun laser daidai.
