Ho tloha ha Einstein a ile a hlahisa khopolo ea mahlaseli a mahlaseli a khanya lekholong le fetileng la lilemo, mochine oa laser o ntlafalitsoe ka botlalo, 'me ka 1960, Maiman o ile a qapa laser ea pele ea optically pumped solid-state laser. Nakong ea tlhahiso ea laser, ho phomola ha mocheso ke ketsahalo ea bohlokoa ea 'mele e tsamaeang le tlhahiso ea laser, e amang haholo ts'ebetso ea laser le matla a teng a laser. Khatholoho ea mocheso le phello ea mocheso esale e nkuoa e le lintlha tsa bohlokoa tsa 'mele tse kotsi ts'ebetsong ea laser, e tlamehang ho fokotsoa ke mekhoa e fapaneng ea phetisetso ea mocheso le mahlale a sehatsetsi. Ka hona, nalane ea ntlafatso ea laser e nkuoa e le nalane ea ntoa le mocheso oa litšila.
Kakaretso ea khopolo-taba ea photon-phonon cooperative pumping laser
Sehlopha sa lipatlisiso se 'nile sa etsa lipatlisiso ka laser le nonlinear optical materials,' me lilemong tsa morao tjena, mokhoa oa ho phomola ha mocheso o 'nile oa utloisisoa ka ho teba ho latela pono ea fisiks ea boemo bo tiileng. Ho ipapisitsoe le mohopolo oa mantlha oa hore mocheso (mocheso) o kenyellelitsoe ka har'a lifonomo tsa microcosmic, ho nahanoa hore ho phomola ha mocheso ka boeona ke ts'ebetso ea quantum ea electron-phonon coupling, e ka khonang ho lemoha ho lokisoa ha maemo a matla a elektronike ka moralo o nepahetseng oa laser, le ho fumana. likanale tse ncha tsa phetoho ea elektronike ho hlahisa maqhubu a machalaser. Ho itšetlehile ka monahano ona, ho hlahisoa molao-motheo o mocha oa tlhahiso ea laser ea electron-phonon cooperative pumping, 'me molao oa phetoho ea elektronike tlas'a electron-phonon coupling o nkoa ka ho nka Nd: YVO4, kristale ea laser ea motheo, e le ntho e emelang. Ka nako e ts'oanang, ho hahoa laser ea "photon-phonon cooperative pumping laser" e sa pholileng, e sebelisang theknoloji e tloaelehileng ea laser diode pumping. Laser e nang le maqhubu a sa tloaelehang a 1168nm le 1176nm e entsoe. Motheong ona, ho itšetlehile ka molao-motheo oa ho hlahisa laser le electron-phonon coupling, ho fumanoa hore sehlahisoa sa laser molokong o mong le mocheso ke ntho e sa fetoheng, e tšoanang le polelo ea molao oa Curie ka magnetism, hape e bontša. molao oa motheo oa 'mele molemong oa phetoho ea mokhahlelo o sa tsitsang.
