Nyochaa usoro ihe omimi nke photon-phonon cooperative pumping laser

Ndị otu nyocha ahụ anọwo na-etinye aka na nyocha laser na nyocha ihe anya na-abụghị nke na-adịbeghị anya, na n'afọ ndị na-adịbeghị anya, a ghọtara usoro ntụrụndụ thermal nke ọma site n'echiche nke physics steeti siri ike. Dabere n'echiche bụ isi na okpomọkụ (okpomọkụ) na-etinye na phonons microcosmic, a na-ewere na ntụrụndụ okpomọkụ n'onwe ya bụ usoro quantum nke njikọ electron-phonon, nke nwere ike ịghọta quantum tailoring nke ike eletrik site na nhazi laser kwesịrị ekwesị, ma nweta ya. Ọwa mgbanwe eletrọn ọhụrụ iji mepụta ogologo ogologo ọhụụlaser. Dabere na echiche a, a na-atụpụta ụkpụrụ ọhụrụ nke electron-phonon cooperative pumping laser generation, na usoro mgbanwe nke eletrọn n'okpuru njikọ electron-phonon na-enweta site n'iji Nd: YVO4, kristal laser bụ isi, dịka ihe nnọchiteanya. N'otu oge ahụ, a na-arụ laser nke na-emekọ ihe ọnụ nke photon-phonon na-adịghị mma, nke na-eji teknụzụ mgbapụta diode omenala laser. Emebere Laser nwere obere wavelength 1168nm na 1176nm. Na ndabere nke a, dabere na isi ụkpụrụ nke laser ọgbọ na electron-phonon njikọ, a na-achọpụta na ngwaahịa nke laser ọgbọ ọnụ ụzọ na okpomọkụ bụ mgbe niile, nke bụ otu ihe ahụ dị ka okwu nke Curie iwu na magnetism, ma na-egosipụtakwa. iwu nke anụ ahụ bụ isi na usoro mgbanwe oge ọgba aghara.
