Tsoelo-pele ea morao tjena mokhoa oa ho hlahisa laser le e nchalipatlisiso tsa laser
Haufinyane tjena, sehlopha sa lipatlisiso sa Moprofesa Zhang Huaijin le Moprofesa Yu Haohai oa State Key Laboratory of Crystal Materials of Shandong University le Moprofesa Chen Yanfeng le Moprofesa He Cheng oa State Key Laboratory of Solid Microstructure Physics of Nanjing University ba sebelitse 'moho ho rarolla bothata bona 'me ba sisinya mokhoa oa ho hlahisa laser oa phoon-phonon collaboration pumping, 'me ba nka kristale ea laser ea Nd:YVO4 ea setso e le ntho e emelang lipatlisiso. Tlhahiso e phahameng ea laser ea superfluorescence e fumanoa ka ho phunyeletsa moeli oa boemo ba matla a elektrone, 'me kamano ea 'mele pakeng tsa moeli oa tlhahiso ea laser le mocheso (nomoro ea phonon e amana haufi-ufi) ea senoloa, 'me sebopeho sa polelo se tšoana le molao oa Curie. Phuputso e phatlalalitsoe ho Nature Communications (doi:10.1038/ S41467-023-433959-9) tlas'a lebitso la "Photon-phonon collaborated pumping laser". Yu Fu le Fei Liang, seithuti sa PhD sa Sehlopha sa 2020, State Key Laboratory of Crystal Materials, Shandong University, ke bangoli ba pele, Cheng He, State Key Laboratory of Solid Microstructure Physics, Nanjing University, ke mongoli oa bobeli, 'me Baprofesa Yu Haohai le Huaijin Zhang, Shandong University, le Yanfeng Chen, Nanjing University, ke bangoli ba tsamaisanang.
Ho tloha ha Einstein a hlahisa khopolo-taba ea mahlaseli a hlasimollang a leseli lekholong la ho qetela la lilemo, mokhoa oa laser o se o ntlafalitsoe ka botlalo, 'me ka 1960, Maiman o ile a qapa laser ea pele e pompeloang ka optically. Nakong ea tlhahiso ea laser, phomolo ea mocheso ke ketsahalo ea bohlokoa ea 'mele e tsamaeang le tlhahiso ea laser, e amang ka botebo ts'ebetso ea laser le matla a laser a fumanehang. Phomolo ea mocheso le phello ea mocheso li 'nile tsa nkoa e le liparamente tsa bohlokoa tse kotsi tsa' mele ts'ebetsong ea laser, tse lokelang ho fokotsoa ke mahlale a fapaneng a phetisetso ea mocheso le sehatsetsing. Ka hona, nalane ea nts'etsopele ea laser e nkoa e le nalane ea ntoa khahlanong le mocheso o litšila.

Kakaretso ea khopolo-taba ea laser ea pompa ea photon-phonon

Sehlopha sa bafuputsi se 'nile sa kopanela lipatlisisong tsa lisebelisoa tsa laser le tse seng tsa optical, 'me lilemong tsa morao tjena, mokhoa oa ho phomola ha mocheso o 'nile oa utloisisoa ka botebo ho latela pono ea fisiks ea boemo bo tiileng. Ho latela khopolo ea motheo ea hore mocheso (mocheso) o kenyelelitsoe lifononeng tse nyenyane tsa bokahohle, ho nkoa hore ho phomola ha mocheso ka bohona ke mokhoa oa quantum oa ho kopanya li-electron-phonon, o ka etsang hore maemo a matla a li-electron a fetoloe ka quantum ka moralo o nepahetseng oa laser, le ho fumana liteishene tse ncha tsa phetoho ea li-electron ho hlahisa bolelele bo bocha ba maqhubu.laser. Ho latela monahano ona, ho sisintswe molao-motheo o mocha wa tlhahiso ya laser ya ho pompa ka kopanelo ya electron-phonon, mme molao wa phetoho ya electron tlasa ho kopanya electron-phonon o nkuwa ka ho nka Nd:YVO4, kristale ya motheo ya laser, e le ntho e emelang. Ka nako e ts'oanang, laser ya photon-phonon e sa phodiswang e a hahuwa, e sebedisang theknoloji ya setso ya ho pompa diode ya laser. Laser e nang le bolelele ba leqhubu bo sa tlwaelehang ba 1168nm le 1176nm e entswe. Motheong ona, ho itshetlehile molao-motheong wa tlhahiso ya laser le ho kopanya electron-phonon, ho fumanwa hore sehlahiswa sa moedi wa tlhahiso ya laser le mocheso ke ntho e sa fetoheng, e leng se tshwanang le polelo ya molao wa Curie ho makenete, mme hape e bontsha molao wa motheo wa mmele tshebetsong ya phetoho ya mohato o sa tsitsang.

Ho phethahala ha teko ea tšebelisano-'moho ea photon-phononho pompa laser

Mosebetsi ona o fana ka pono e ncha bakeng sa lipatlisiso tsa morao-rao mabapi le mokhoa oa ho hlahisa laser,fisiks ea laser, le laser e nang le matla a mangata, e supa tekanyo e ncha ea moralo bakeng sa theknoloji ea katoloso ea bolelele ba leqhubu la laser le tlhahlobo ea kristale ea laser, 'me e ka tlisa mehopolo e mecha ea lipatlisiso bakeng sa nts'etsopele eali-optic tsa quantum, meriana ea laser, ponts'o ea laser le masimo a mang a amanang le ts'ebeliso.
