Laser Optics - Qaybta 2

Optics-yada aan bixinayno waxay daboolayaan laser optics;nalka laysarka ;polarizing optics iyo farsamaynta walxaha infrared.Oo ay ku jiraan daaqadaha, muraayadaha, muraayadaha.Guud ahaan, indho-indhayntayada waxa la keenaa iyada oo aan la rakibin ama aan la rakibin sida ku cad codsiga macaamiisha.

Meel eber

Waveplate eber waxaa loogu talagalay in lagu siiyo dib u dhigista eber mawjadaha buuxa, oo lagu daray jajabka la rabo. codsiyo aad muhiim u ah.
Achromatic Waveplates

Achromatic waveplates iyadoo la isticmaalayo laba xabbadood oo saxan ah. Waxay la mid tahay Zero-order waveplate marka laga reebo in labada taarikada laga sameeyay walxo kala duwan, sida quartz crystal iyo magnesium fluoride.Maaddaama kala firdhinta birefringence ay ka duwanaan karto labada shay, waxaa suurtagal ah in lagu qeexo qiyamka dib u dhaca ee xadka hirarka.
Mawjadaha Mawjadaha Dhererka laba-geesoodka ah

Waveplate mowjadaha dhererka laba-geesoodka ah ayaa si weyn loogu isticmaalaa nidaamka Jiilka Saddexaad ee Harmonic (THG).Markaad u baahato crystal NLO nooca II SHG (o+e →e), iyo NLO crystal nooca II THG (o+e →e), polarization ka soo baxay SHG looma isticmaali karo THG.Markaa waa inaad u rogtaa polarization-ka si aad u hesho laba indhood oo toosan oo ah nooca II THG.Mawjadaha mawjadaha dhererka laba-geesoodka ah waxa uu u shaqeeyaa sida rotator-ka-badalka ah, waxa uu beddeli karaa polarization-ka hal laydh oo waxa uu ahaan karaa kala-soocidda beam kale.
Glan Laser Polarizer

Glan Laser prism polarizer wuxuu ka samaysan yahay laba qaybood oo isku mid ah oo ka samaysan birefringent kuwaas oo lagu ururiyey meel hawo leh.Polarizer-ku waa wax ka beddelka nooca Glan Taylor waxaana loogu talagalay in uu yeesho luminta milicsiga isgoysyada priismka.Polarizer-ka leh laba daaqadood oo baxsad ah ayaa u oggolaanaya laydhka la diiday inuu ka baxsado polarizer-ka, taas oo ka dhigaysa mid aad loogu jecel yahay leysarka tamarta sare.Tayada dusha sare ee wejiyadani aad ayay u liidataa marka loo eego kuwa laga soo galo iyo kuwa ka baxaba.Ma jiro xoqin qodaya tayada dusha sare ee tayada wejiyadan.
Glan Taylor Polarizer

Glan Taylor polarizer waxa uu ka samaysan yahay laba qalab oo birefringent ah oo isku mid ah kuwaas oo lagu soo ururiyey meel hawo ah. Dhererkeeda ilaa saamiga daloolka oo ka yar 1.0 ayaa ka dhigaysa polarizer khafiif ah. Codsiga halka dhinaca loo diiday alwaaxyada aan loo baahnayn .Xagalka xagasha ee alaabta kala duwan ee polarizers ayaa hoos ku taxan marka la barbardhigo.
Glan Thompson Polarizer

Glan-Thompson polarizers waxay ka kooban yihiin laba prisms sibidh ah oo laga sameeyay heerka ugu sarreeya ee indhaha ee calcite ama a-BBO crystal.Iftiin aan cidhiidhi ahayn ayaa gasha polarizer-ka waxana uu kala qaybsan yahay isdhexgalka labada kiristaalo.Fallaadhaha caadiga ah waxay ka muuqdaan is-dhexgal kasta, taasoo keenaysa inay kala firdhiyaan oo qayb ahaan ay nuugaan guryaha polarizer-ka.Fallaadhaha aan caadiga ahayn waxay si toos ah u dhex maraan polarizer-ka, iyaga oo bixinaya wax soo saarka dabaylaha.
