Indlela yobugcisa engundoqo yeelaser ezinobubanzi obumxinwa obunokutyibilika

Eyona ndlela yobugcisa yeiilaser ezinobubanzi obumxinwa

Ezona ndlela ziphambili zobugcisa zokuthuthalasers emxinwa-linewidthenemingxuma yangaphandle ye-semiconductor

Iilaser ezinobubanzi obumxinwa obucacileyo zisisiseko sosetyenziso olubanzi kwiinkalo ezifana nefiziksi yeatom, i-spectroscopy, ulwazi lwe-quantum, unxibelelwano oluhambelanayo, imvakalelo ekude, kunye nomlinganiselo ochanekileyo. Kwezi nkalo, ezilula, ezinexabiso eliphantsi, ububanzi bomgca obumxinwa kunye noluhlu olubanzi lwelaser luya kuqhubeka nokuqhuba usetyenziso olutsha kobu buchwepheshe.

Kwiminyaka engama-50 edlulileyo, imbali yeumthombo wokukhanya onokusebenzisekaI-TLS Laser ibonakalise ubukhulu becala uphuhliso lobuchwepheshe belaser. I-laser yokuqala yedayi ithathelwe indawo yi-laser diode yangaphandle ye-cavity (ECDLs), ngelixa iinkqubo eziphezulu zamandla zilawulwa yi-laser ye-solid-state lasers (njenge-titanium-sapphire lasers) okanye i-frequency-converted Nd: YAG lasers usebenzisa i-oscillators oscillators optical parametric (OPO). I-laser ye-Diode ngaphandle kwe-cavities yangaphandle ezinzileyo igcwalise isiphelo semarike esinexabiso eliphantsi kunye nesezantsi kunye ne-DFB ye-Laser yorhwebo kunye ne-DBR diodes, kunye nobubanzi bomgca obuncinci njenge-500kHz. Kutshanje, iilaser zefiber kunye ne-laser-frequency fibre lasers ziye zaqala ukutshintsha iinkqubo ezininzi zombuso oqinileyo ngoyilo olwahlukileyo, zibonelela ngamandla aphezulu kunye nokuthunwa okukhulu, okanye ububanzi bemigca emxinwa. Kule mihla, ukuvela kwee-frequency cobs zenza ukuba ii-laser ezizinzisiweyo zifumaneke kulo naliphi na i-wavelength ngelixa kugcinwa uzinzo kunye nokuchaneka okugqwesileyo. Nangona kunjalo, nangona oku, i-cavity yangaphandlesemiconductor laserisagcina isimo sayo njengomthombo wokukhanya osetyenziswa ngokuqhelekileyo kwiilabhoratri ezininzi ngenxa yokulula kwayo, imisebenzi emininzi, ukusebenza okuhloniphekileyo kunye neendleko eziphantsi kakhulu.

Okwangoku, iilaser ezinobubanzi obumxinwa obunokutyibilika ezinesemiconductors yangaphandle ziye zasetyenziswa ngokubanzi apha:

Ukupholisa kweLaser kunye nokubamba

Bose-Einstein condensation

I-Quantum Optics: Ukukhanya okucinezelweyo

I-electromagnetic transparent kunye nokukhanya okucothayo

Ixesha kunye nemigangatho yobuninzi

I-Laser spectroscopy

Iilaser ezinobubanzi obumxinwa obusekwe ngokuqhelekileyo ziqulunqwe sisilawuli, i-laser diode kunye nemodyuli yokukhetha frequency. Umzekelo, iigrayiti ezisetyenziselwa ukukhetha amaza e-laser kunye nokulungiswa, okanye izihluzi ezisekwe kulwakhiwo lweliso lekati, njl. njl. Ukufezekisa uzinzo oluphezulu lwe-laser, iintlobo ezahlukeneyo zeemodyuli zokutshixa i-laser zinokongezwa. Ngokomzekelo, ngokusebenzisa iteknoloji ye-PDH yokuzinzisa iteknoloji ukuvala i-laser wavelength kwi-optical super-stable cavity, ububanzi bomgca we-laser bunokucuthwa ukuya kwinqanaba le-1 Hz, kwaye ukuzinza kwe-frequency kunokufikelela <3 × 10-15 @ 1 s.
