HAMAMATSU, Japan, Ọgọst 25, 2021-Hamamatsu Photonics na National Institute of Advanced Industrial Science and Technology (AIST) dị na Tokyo jikọrọ aka na sistemụ nleba anya ikuku, obere ikuku maka ịkọ amụma mgbawa ugwu na oke mmetụta. Na mgbakwunye na inye nleba anya ogologo oge nke ikuku mgbawa dị nso na ndagwurugwu mgbawa, enwere ike iji onye nyocha mkpanaaka chọpụta gas na-agbapụta na osisi kemịkalụ na nsị mmiri yana maka nha ikuku.

Usoro a nwere miniaturized, wavelength-sweep quantum cascade laser (QCL) nke Hamamatsu mepụtara. N'ihe dị ka 1/150 nke nha QCL ndị gara aga, laser bụ QCL nke kacha pere mpe. Sistemụ draịva maka sistemụ nleba anya gas, nke AIST mepụtara, ga -enye ohere itinye obere QCL ka ọ bụrụ ihe dị nfe na obere nyocha enwere ike iburu ebe ọ bụla.
QCL kacha nta ebili mmiri nke ụwa kpochapụrụ bụ naanị 1/150th nha nke QCL nke ebili mmiri ogologo gara aga. Site n'ikike Hamamatsu Photonics KK na New Energy and Industrial Technology Development Organisation (NEDO).
N'iji teknụzụ microelectromechanical sistemu (MEMS) nke Hamamatsu, ndị nrụpụta rụzigharịrị QCL's MEMS diffraction grating, na -ebelata ya n'ihe dịka 1/10 nha nha. Ndị otu ahụ werekwara obere ndọta nke ahaziri iji belata oghere na -enweghị isi, wee kpọkọta ihe ndị ọzọ nke ọma na nkeji 0.1 μm. Akụkụ mpụga nke QCL bụ 13 × 30 × 13 mm (W × D × H).

QCL na-ebili mmiri na-eji ihe mkpuchi MEMS nke na-agbasasị, na-egosipụta, ma na-enwu ọkụ n'etiti-infrared ka ọ na-agbagharị ogologo ntụgharị ngwa ngwa. QCL nke Hamamatsu na-efegharị efegharị nwere ike ịnagide ya na oke ebili mmiri nke 7 ruo 8 μm. Igwe ọkụ SO2 na H2S na -amịkọrọ oghere a n'ụzọ dị mfe nke a na -ewere dị ka ndị na -ebu amụma mmalite mgbawa ugwu.

Iji mezuo ogologo ntụgharị ntụgharị, ndị nyocha ahụ jiri teknụzụ imepụta ngwaọrụ dabere na mmetụta kwantum. Maka oyi na-enwupụta ọkụ nke ihe QCL, ha jiri ihe eji eme ihe gafere steeti abụọ.

Mgbe ejikọtara QCL wavelength na sistemụ draịvụ nke AIST mepụtara, ọ nwere ike nweta oke nfe nfe nke na-enweta ụdịdị ọkụ infrared na-aga n'ihu n'ime 20 ms. Nnweta ngwa ngwa QCL nke ụdịdị dị iche iche ga-eme ka nyocha nke ihe na-agafe agafe na-agbanwe ngwa ngwa ka oge na-aga. Mkpebi ngosipụta nke QCL bụ ihe dịka 15 nm, ihe kacha kacha pụta bụ ihe dịka 150 mW.

Ka ọ dị ugbu a, ọtụtụ ndị nyocha eji achọpụta ma tụọ gas mgbawa na ozugbo nwere ihe mmetụta elektrọnik. Igwe ọkụ dị na ihe mmetụta ndị a - yana arụmọrụ nke onye nyocha - na -emebi ngwa ngwa, n'ihi ikpughe gas na -egbu egbu mgbe niile. Ndị na-enyocha gas niile na-eji ọkụ ọkụ ogologo ndụ ma chọọ obere mmezi, mana ọkụ ọkụ nwere ike weghara nnukwu oghere. Ogo ndị nyocha a na -eme ka o sie ike ịwụnye ha n'akụkụ oke mgbawa ugwu.

Usoro nleba anya gas na-esote mgbawa ọkụ, nke nwere QCL nke nwere ogologo ebili mmiri, ga-enye ndị na-ahụ maka ugwu mgbawa ihe anya, kọmpat, obere mkpanaaka nke nwere oke mmetụta na ndozi dị mfe. Ndị nyocha ahụ na Hamamatsu na ndị ọrụ ibe ha na AIST na New Energy and Industrial Technology Development Organisation (NEDO), nke kwadoro ọrụ ahụ, ga -aga n'ihu nyocha ụzọ iji bulie uche onye nyocha wee belata mmezi.

Ndị otu a na -eme atụmatụ nleba anya ọtụtụ iji nwalee ma gosipụta onye nyocha obere mkpanaaka. Ngwaahịa na-eji QCL ogologo-ebili mmiri na okirikiri ụgbọ ala yana Hamamatsu photodetector ezubere maka mwepụta na 2022.
