Co2+: MgAl2O4 Qalab Cusub oo loogu talagalay Nuugista Saturable Q-switch

Sharaxaad Gaaban:

Co: Spinel waa shay cusub oo loogu talagalay nuugista buuxda ee Q-beddelka laysarka ee ka soo baxaya 1.2 ilaa 1.6 microns, gaar ahaan, isha-ammaan ah 1.54 μm Er: laser galaas. Qaybta nuugista sare ee 3.5 x 10-19 cm2 waxay ogolaataa Q-beddelka Er: laser galaas

Sharaxaada Alaabta

Qaybta nuugista sare ee 3.5 x 10-19 cm2 waxay ogolanaysaa Q-beddelka Er: laserka muraayadda iyada oo aan lahayn godad dhexda ah oo diiradda saaraya labadaba nalka iftiinka iyo bamgareynta diode-laser. Natiijooyinka nuugista xiisaha leh ee dawlad-goboleedka ah ee ka soo horjeeda sare ee Q-bedelka, ie saamiga bilowga (calaamadaha yar) ilaa nuugista buuxda ayaa ka sarreysa 10. Ugu dambeyntii, sifooyinka wanaagsan ee indhaha, farsamada, iyo kulaylka ee crystals waxay siinayaan fursad lagu naqshadeeyo is haysta. iyo ilo laser ah oo lagu kalsoonaan karo oo leh Q-switch-kan dadban.
Baaxadda aaladda waa la dhimay waxaana meesha laga saarayaa isha korontadu sareeyso marka Q-switch-yada dadban ama nuugiyaasha saturable loo isticmaalo si loo abuuro garaaca leysarka awoodda sare halkii ay ka ahaan lahaayeen koronto-optic Q-dalalka. Karistanka adag, adag ee loo yaqaan spinel polishes si fiican. Iyadoo aan lahayn ions magdhow ah oo dheeraad ah, kobalt waxaa laga yaabaa inay si fudud u beddesho magnesium ee martida lafdhabarta. Labadaba bamgaraynta laysarka-lamp-ka iyo diode-ka, Er:galaas laser's nuugista sare ee qaybta iskutallaabta (3.510-19 cm2) waxay u ogolaataa Q-beddelka iyada oo aan diiradda la saarin.
Celceliska awoodda wax soo saarku waxay noqon doontaa 580 mW oo leh ballac garaaca wadnaha oo hooseeya sida 42 ns iyo awoodda bamka la nuugo ee 11.7 W. Tamarta garaaca garaaca wadnaha Q-kaliya waxaa lagu xisaabiyay qiyaastii 14.5 J, awoodda ugu sarreysana waxay ahayd 346 W ku celcelinta qiyaastii 40 kHz. Sidoo kale, dhawr dawladood oo kala duwanaansho ah oo ka mid ah Co2+: LMA ficilka beddelka Q dadban ayaa la baadhay.
