Indlela eyinhloko yobuchwepheshe yeama-laser anobubanzi obuncane obulungisekayo

Izindlela eziyinhloko zobuchwepheshe zokulungisaama-laser anobubanzi obuncaneenezimbobo zangaphandle ze-semiconductor

Ama-laser alula, ashibhile, alula, alula, alula, alula, alula kanye nama-laser abanzi azoqhubeka nokuqhuba izinhlelo zokusebenza ezintsha zalobu buchwepheshe.

Eminyakeni engama-50 edlule, umlando we-umthombo wokukhanya olungisekayoI-TLS Laser ibonakalise kakhulu intuthuko yobuchwepheshe be-laser. Ama-laser okuqala odayi athathelwe indawo ama-laser e-diode angaphandle (ama-ECDL), kuyilapho izinhlelo zamandla aphezulu zibuswa ama-laser aqinile alungisekayo (njenge-titanium-sapphire lasers) noma ama-laser e-Nd:YAG aguqulwe ngemvamisa asebenzisa ama-oscillator e-optical parametric (OPO). Ama-laser e-diode angenazo izimbobo zangaphandle ezizinzile agcwalise imakethe engabizi kakhulu nesebenza kahle ngama-diode e-DFB Laser nama-DBR, anobubanzi bomugqa obuncane njengo-500kHz. Muva nje, ama-laser e-fiber kanye nama-laser e-fiber aguquguqukayo aqale ukufaka esikhundleni sezinhlelo eziningi ze-solid-state ngemiklamo ehlukene, enikeza amandla aphezulu kanye nokulungiswa okukhulu, noma ububanzi bomugqa obuncane. Namuhla, ukuvela kwama-frequency combs kwenza ama-laser azinzile ngemvamisa atholakale kunoma yiluphi ubude be-wavelength ngenkathi kugcinwa ukuzinza nokunemba okuhle kakhulu. Kodwa-ke, naphezu kwalokhu, imbobo yangaphandlei-laser ye-semiconductorisalondoloza isimo sayo njengomthombo wokukhanya osetshenziswa kakhulu ezindaweni eziningi zokucwaninga ngenxa yobulula bayo, ukusebenza kwayo okuningi, ukusebenza kwayo okuhloniphekile kanye nezindleko eziphansi kakhulu.

Njengamanje, ama-laser alula obubanzi obuncane anama-semiconductor angaphandle asetshenziswe kabanzi ku:

Ukupholisa nokubamba nge-laser

Ukujiya kwe-Bose-Einstein

I-Quantum Optics: Ukukhanya okucindezelwe

Ukukhanya okubonakalayo kwe-electromagnetic kanye nokukhanya okuhamba kancane

Izindinganiso zesikhathi kanye nemvamisa

I-spectroscopy ye-laser

Ama-laser anobubanzi obuncane obunokulungiswa ngokuvamile akhiwa isilawuli, i-laser diode kanye nemojuli yokukhetha imvamisa. Isibonelo, ama-grating asetshenziselwa ukukhetha nokulungisa imvamisa ye-laser, noma izihlungi ezisekelwe esakhiweni seso lekati, njll. Izici ezibalulekile zama-laser anobubanzi obuncane obunokulungiswa anama-semiconductors angaphandle afaka phakathi ububanzi obuncane be-laser, ukushelela okuphansi kwemvamisa, kanye nobubanzi bokulungisa obubanzi, njll. Futhi lezi zici ezivelele zincike kusekethe yokushayela ye-laser enhle kakhulu, ukuzinza komshini okuphelele kwe-laser, kanye nomgomo wokukhetha imvamisa. Ukuze kufezwe ukuzinza okuphezulu kwemvamisa ye-laser, izinhlobo ezahlukene zamamojula okukhiya imvamisa ye-laser zingangezwa. Isibonelo, ngokusebenzisa ubuchwepheshe bokuzinza kwemvamisa ye-PDH ukuvala ubude be-laser ku-cavity ezinzile kakhulu ye-optical, ububanzi be-laser bungancishiswa bufike ezingeni le-1 Hz, futhi ukuzinza kwemvamisa kungafinyelela ku-< 3 × 10-15 @ 1 s.
