- Shuruudaha Isha Bamka Fiber Lasers
Diodes-ka laysarkasida Ilo Bamka:Laydhka fiilooyinka ayaa inta badan u isticmaala diode-yada laysarka inay yihiin isha bamka sababtoo ah waxtarkooda, cabbirkooda yar, iyo awoodda ay u leeyihiin inay soo saaraan hirar iftiin oo gaar ah oo la jaanqaadaya muuqaalka nuugista ee faybka la daweeyay. Doorashada hirarka diode-ka laysarka waa muhiim; tusaale ahaan, dopant-ka caadiga ah ee ku jira laysarka fiber-ka waa Ytterbium (Yb), kaas oo leh ugu badnaan nuugista ugu fiican qiyaastii 976 nm. Sidaa darteed, diode-yada laysarka ee ka soo baxa hirarkan ama u dhow ayaa la door bidaa in lagu shubo laydhka fiber-ka Yb-doped.
Naqshad Fiber Laba-xidhan leh:Si loo kordhiyo hufnaanta nuugista iftiinka ee ka imanaya diode-yada laysarka bamka, laysarka fiber-ka badanaa waxay isticmaalaan naqshad faybar laba-laaban leh. Xudunta gudaha waxaa lagu dahaadhay dhexdhexaadka laysarka firfircoon (tusaale ahaan, Yb), halka lakabka dahaarka ee dibadda oo weyn uu hago iftiinka bamka. Xudunta ayaa nuugta iftiinka bamka waxayna soo saartaa ficilka laysarka, halka dahaarka uu u oggolaanayo in iftiin badan oo bamka ah uu la falgalo xudunta, taasoo kor u qaadaysa hufnaanta.
Isku-habaynta Mowjadaha iyo Waxtarka Isku-xidhkaBamgareynta wax ku oolka ah waxay u baahan tahay oo keliya xulashada diode-yada laysarka leh hirarka ku habboon, laakiin sidoo kale hagaajinta hufnaanta isku xidhka u dhexeeya diode-yada iyo faybarka. Tani waxay ku lug leedahay iswaafajin taxaddar leh iyo isticmaalka qaybaha indhaha sida muraayadaha iyo isku xidhka si loo hubiyo in iftiinka bamka ugu badan lagu shubo xudunta fiber-ka ama dahaarka.
-Laser-yada AdagShuruudaha Isha Bamka
Bamka indhaha:Marka laga reebo diode-yada laysarka, laysarka adag (oo ay ku jiraan laysarka waaweyn sida Nd:YAG) waxaa lagu shubi karaa laambado iftiin ama laambado qaanso ah. Laambadahani waxay soo saaraan iftiin ballaaran, oo qayb ka mid ah ay la mid yihiin xargaha nuugista ee dhexdhexaadka laysarka. In kasta oo ay ka waxtar yar tahay bamgareynta diode-ka laysarka, habkani wuxuu bixin karaa tamar garaac oo aad u sarreeya, taasoo ka dhigaysa mid ku habboon codsiyada u baahan awood sare.
Qaabeynta Isha Bamka:Qaabeynta isha bamka ee laysarka adag waxay si weyn u saameyn kartaa waxqabadkooda. Bamka dhammaadka iyo bamka dhinaca waa qaabab caadi ah. Bamka dhammaadka, halkaas oo iftiinka bamka lagu jiheeyo dhidibka indhaha ee dhexdhexaadka laysarka, wuxuu bixiyaa isku-dhaf wanaagsan oo u dhexeeya iftiinka bamka iyo qaabka laysarka, taasoo horseedaysa hufnaan sare. Bamka dhinaca, inkastoo ay suurtogal tahay inuu ka waxtar yar yahay, way fududahay waxayna bixin kartaa tamar guud oo sare oo loogu talagalay ulaha ama looxyada dhexroorka weyn.
Maareynta Kulaylka:Labada laser ee fiber-ka iyo kuwa adag waxay u baahan yihiin maareyn kuleyl oo wax ku ool ah si ay ula tacaalaan kulaylka ay soo saaraan ilaha bamka. Laser-yada fiber-ka, baaxadda dusha sare ee fiber-ka ayaa ka caawisa kala-baxa kulaylka. Laser-yada adag, nidaamyada qaboojinta (sida qaboojinta biyaha) ayaa lagama maarmaan u ah si loo ilaaliyo hawlgalka deggan iyo ka hortagga muraayadda kulaylka ama dhaawaca soo gaara habka laser-ka.
