Ma garanayno tignoolajiyada laysarka

Ma garanayno tignoolajiyada laysarka, 1960-kii waxay ahayd kaliya wax-soo-saarka laysarka ee ugu horreeya.In the case of laser waa diyaarinta teori iyo dhaqanka wax soo saarka degdeg ah loo baahan yahay asalka soo baxay, waxaa soo baxay, si aad u hesho horumarinta degdeg ah oo aan caadi ahayn, ma aha oo kaliya horumarinta laser si ay cilmiga qadiimiga ah ee indhaha iyo teknoolajiyada indhaha helay nolol cusub, laakiin sidoo kale waxay keenaysaa soo bixitaanka albaab cusub oo warshadeed.Mashiinka goynta laser-ka ayaa awood u siinaya dadka inay si wax ku ool ah u adeegsadaan hababka horumarsan ee aan horay loo arag, si ay u helaan faa'iidooyin iyo natiijooyin aan horay loo arag, si kor loogu qaado horumarinta ciidamada wax soo saarka.

Si kastaba ha ahaatee, sida goynta laser laser, alxanka laysarka, mashiinka goynta laser ayaa si ballaaran loo isticmaalo nolosha ka mid ah wax soo saarka, laakiin sidoo kale laser crystal, laser terahertz aqoonta noocan oo kale ah, waxaan dhif la xiriirnay qoraaga maqaalkani wuxuu horseedaa qof walba inuu eego kuwa aynaan haysan. aqoon u leh farsamada laysarka.

Mashiinka goynta laser-ka tamarta kristal waxaa lagu siin karaa dalool indhaha dibadda ah oo ku jira isku xirnaanta booska iyo ku-meel-gaarka ee agabka crystalline-ka ayaa si aad ah u barbar socda iyo iftiinka laser monochromatic.Qalabka shaqada waa laser crystal.Karistaanka Laser ee xarumaha luminescence iyo kiristaalo matrix ka kooban laba qaybood.Inta badan xarunta iftiiminta iftiinka iyada oo la hawlgelinayo qaab-dhismeedka crystal ion laser, ions firfircoon qayb ahaan beddelo cation matrix crystals doped crystals laser.Marka aad hawlgeliso ion-ku waxa uu noqdaa qayb ka mid ah qaybaha crystal-ka martida loo yahay, waxa ay ka kooban tahay crystal laser iskii u shaqaynaya.

Mashiinka goynta Laser crystal crystal loo isticmaalo inta badan ion birta kala guurka firfircoon iyo trivalent dhif-dhul aions.ion biraha kala guurka indhaha elektarooniga ah waa in lakabka dibadda 3 d electrons in crystals sida elektarooniga indhaha u nugul saamaynta tooska ah ee beerta crystal agagaarka, sidaas noocyada kala duwan ee qaab-dhismeedka crystal, sifooyinka ay spectral aad u kala duwan.Trivalent dhif ah ion dhulka 4 f electrons yihiin saamaynta gaashaan 5 s iyo 5 p electrons dibadda, si garoonka crystal daciifin doorkeeda, laakiin doorka kristal field perturbation sababaha ayaa la mamnuucay. iyo line fluorescence.Sidaas awgeed trivalent dhif ah-dhulka aions ee spectra ee kala duwan ee biraha kala guurka crystal sida isbedel aad u badan.
