Ukuncishiswa kweububanzi bomugqa we-laser
Ububanzi bomugqa we-laser buhlobene ngqo nohlobo lwe-laser. Ububanzi bomugqa we-laser bungancishiswa ngokwenza ngcono ukwakheka kwe-laser nokunciphisa ithonya lomsindo wangaphandle ngangokunokwenzeka. Isinyathelo sokuqala ukunquma ukuthi yimuphi oyinhloko, umsindo we-quantum noma umsindo we-classical, njengoba lokhu kuzothinta izilinganiso ezilandelayo.
Uma amandla okungena ngaphakathi kwe-cavity ephezulu, ukulahleka kwe-resonator kuphansi futhi isikhathi sokuya nokubuya kwe-resonator side, umsindo we-quantum we-i-laser(ikakhulukazi umsindo wokukhipha umoya ozenzakalelayo) unomthelela omncane kakhulu. Umsindo wendabuko ungabangelwa ukukhukhuleka komshini. Ukuguquguquka kungancishiswa ngokusebenzisa i-resonator ye-laser emfushane emfushane, kodwa ngezinye izikhathi kuma-resonator amafushane, ukushintshashintsha kobude kungaveza umphumela onamandla. Umklamo ofanele womshini unganciphisa ukuhlangana phakathi kwe-resonator ye-laser kanye nemisebe yangaphandle, futhi kunciphise nomphumela wokushisa. Kukhona nokuguquguquka kokushisa endaweni yokuzuza, okubangelwa ukushintshashintsha kwamandla ephampu.
Ukuze umsindo usebenze kangcono, kudingeka kusetshenziswe amanye amadivayisi okuzinzisa asebenzayo, kodwa kungcono ukusebenzisa izindlela ezisebenzayo zokuqala. Ububanzi bomugqa we-laser yesimo esiqinile semvamisa eyodwa kanyei-fiber laseringama-kilohertz amaningana, futhi ngezinye izikhathi ingaphansi kuka-1KHz. Ngokusebenzisa indlela yokuzinza esebenzayo, ububanzi bomugqa obungaphansi kuka-1KHz bungatholakala. Ububanzi bomugqa wama-laser diode buvame ukuba sebangeni le-MHZ futhi bungancishiswa bube yi-KHz, njengakuma-laser e-diode e-cavity yangaphandle, ikakhulukazi kuma-diode e-optical feedback ane-cavity yokubhekisela enembile kakhulu.
Kuyafaneleka ukuqaphela ukuthi kwezinye izimo,umthombo wokukhanya we-laserAkudingeki ukukhiqiza ububanzi bokukhanya obuncane kakhulu:
1. Uma ubude bokuhambisana bude, umphumela wokuhambisana (ngenxa yokubonakaliswa okubuthakathaka kwe-parasitic) uzophazamisa ukuma komsebe wokukhanya. Ekubonisweni kwe-laser projection, umphumela we-speckle ungaphazamisa ikhwalithi yendawo ebuyayo.
2. Uma ukukhanya kudluliselwa ngemicu ye-optical esebenzayo noma engasebenzi, ububanzi bemigqa emincane bubangela izinkinga ezithile ngenxa yokusabalala kwe-Brillouin okukhuthaziwe. Kuleli qophelo, ububanzi bomugqa budinga ukwanda, isibonelo, ngokushintsha i-laser diode ngogesi noma ukusebenzisa i-optical modulator ukuze kusheshiswe imvamisa esheshayo. Ububanzi bomugqa busetshenziswa kwezinye izimo. Ububanzi bomugqa busetshenziswa futhi ukuchaza ububanzi bokubola kwe-optical
