Tsis ntev los no, Department of Advanced Laser thiab Optoelectronic Functional Materials ntawm Shanghai Institute of Optics thiab Precision Machinery, Suav Academy ntawm Kev Tshawb Fawb, tau ua tiav hauv kev tshawb fawb ntawm Nd: ASL (Sr0．7Nd0．05La0．25Mg0．3Al22．7O19) laser crystals, cov txiaj ntsig tau luam tawm hauvInfrared Physics & Technologynyob rau hauv lub npe ntawm "Tunable laser ua haujlwm ntawm Nd-doped strontium thiab lanthanum aluminate crystals".
Neodymium (ND3+) ions yog ib qho ntawm cov nquag nquag siv ions, thiab lawv qhov siab nqus tau zoo sib xws cov emission wavelengths ntawm kev lag luam.laser diodes(LDs) nrog kev nqus tau zoo, nrog cov pa tawm siab tshaj plaws ntawm 0.9, 1.05, thiab 1.35 μm, thiab cov emission laser tau txais ntau yam khoom siv substrate. Kev nthuav dav, uas yog qhov zoo rau kev tsim cov lasers ntawm qhov sib txawv wavelengths.
Txhawm rau tshawb xyuas nws cov khoom tuning, pab pawg tau loj hlob Nd: ASL crystals nrog doping concentration ntawm 5%, thiab ntsuas nws lub neej fluorescence txog 371.8 μs. Lub fluorescence spectrum muaj plaub lub zog thiab txuas ntxiv emission spectrum nyob ib ncig ntawm 1.05 μm. Lub lim dej birefringent tau muab tso rau hauv V-shaped resonant kab noj hniav rau tunable laser thwmsim, thiab laser outputs ntawm peb ywj siab wavelengths (1050, 1062, thiab 1074 nm) tau los ntawm kev ua hauj lwm tso zis tsom iav nrog transmittances ntawm 5%, 7%, thiab 10 %. Cov wavelengths tau kho nyob rau hauv thaj tsam ntawm 1049.59-1054.43 nm thiab 1059.71-1078.18 nm, thiab qhov dav dav dav dav dua 20 nm, uas tau pom zoo nrog cov spectra. Lub multi-wavelength laser tso zis tshwm sim kuj tau pom nyob rau hauv qhov kev sim. Cov txiaj ntsig tau qhia tias Nd: ASL siv lead ua yog qhov tsim nyog nce nruab nrab rau tunablelasers, thiab nws yooj yim dua rau kev tswj thiab hloov lub wavelength ntau dua li tsuas yog ib lub wavelength laser nruab nrab xwb, uas yog tsim rau complex daim ntawv thov scenarios nrog siab precision los yog ntau wavelengths.
Txoj haujlwm no tau txais kev txhawb nqa los ntawm National Natural Science Foundation ntawm Tuam Tshoj thiab lwm cov haujlwm.
