Ballaca garaaca ee Laser-yada la riixay

Ballaca garaaca waxaa loola jeedaa muddada garaaca wadnaha, baaxadduna waxay caadi ahaan ka bilaabataa nanoseconds (ns, 10)^-9ilbiriqsiyo) ilaa femtoseconds (fs, 10)^-15ilbiriqsiyo). Laysarrada garaaca leh ee leh ballaca garaaca kala duwan ayaa ku habboon codsiyada kala duwan:

- Ballaca Gaaban ee Garaaca (Picosecond/Femtosecond):

Ku habboon in si sax ah loo farsameeyo walxaha jilicsan (tusaale ahaan, galaaska, safayr) si loo yareeyo dildilaaca.

- Ballaca Garaaca Dheer (Nanosecond): Ku habboon jarista birta, alxanka, iyo codsiyada kale ee loo baahan yahay saameynta kulaylka.

- Femtosecond Laser: Waxaa loo isticmaalaa qalliinnada indhaha (sida LASIK) sababtoo ah waxay samayn kartaa jaritaanno sax ah iyadoo waxyeello yar soo gaarta unugyada ku xeeran.

- Garaacyada Ultrashort: Waxaa loo isticmaalaa in lagu barto hababka firfircoon ee aadka u dheereeya, sida gariirka molecular-ka iyo falcelinta kiimikada.

Ballaca garaaca ayaa saameeya waxqabadka laysarka, sida awoodda ugu sarreysa (P)_{meesha ugu sarreysa}= tamarta garaaca/ballaca garaaca. Ballaca garaaca oo gaaban, ayaa awoodda ugu sarreysa ee tamarta hal-garaaca ah ay sare u kacaysaa.) Waxay sidoo kale saamaysaa saamaynta kulaylka: ballaca garaaca dheer, sida nanoseconds, waxay sababi kartaa ururinta kulaylka ee agabka, taasoo horseedaysa dhalaalid ama dhaawac kuleyl; ballaca garaaca gaaban, sida picoseconds ama femtoseconds, waxay awood u siinaysaa "habaynta qabow" iyadoo la yareynayo aagagga ay kulaylka saameeyeen.

Laydhka fiilooyinka ayaa caadi ahaan xakameeya oo hagaajiya ballaca garaaca iyadoo la adeegsanayo farsamooyinka soo socda:

1. Beddelidda Q: Waxay soo saartaa garaaca nanosecond iyadoo si joogto ah u beddeleysa khasaaraha resonator-ka si ay u soo saarto garaaca tamar sare leh.

2. Qaabka-Xadhiga: Waxay soo saartaa garaaca picosecond ama femtosecond ultrashort iyadoo la isku dubaridayo qaababka dhererka ee gudaha resonator-ka.

3. Waxyeellooyinka ama Saamaynta Aan Toosnayn: Tusaale ahaan, isticmaalka Wareegga Kala-soocidda Aan Toosnayn (NPR) ee fiilooyinka ama nuugayaasha buuxa si loo cadaadiyo ballaca garaaca.
