GaSe crystals
Siv lub GaSe siv lead ua cov zis wavelength tau kho nyob rau hauv thaj tsam ntawm 58.2 µm mus rau 3540 µm (los ntawm 172 cm-1 txog 2.82 cm-1) nrog lub ncov fais fab mus txog 209 W. Kev txhim kho tseem ceeb tau ua rau lub zog tso zis ntawm THz no. Qhov chaw ntawm 209 W rau 389 W.
ZnGeP2 siv lead ua
Ntawm qhov tod tes, raws li DFG hauv ib ZnGeP2 siv lead ua cov zis wavelength tau tuned nyob rau hauv thaj tsam ntawm 83.1–1642 µm thiab 80.2–1416 µm rau ob theem txuam configurations, ntsig txog.Lub hwj chim tso zis tau mus txog 134 W.
GAP crystals
Siv lub GaP siv lead ua qhov tso zis wavelength tau tuned nyob rau hauv thaj tsam ntawm 71.1-2830 µm whereas lub siab tshaj plaws lub hwj chim yog 15.6 W.Qhov zoo ntawm kev siv GaP tshaj GaSe thiab ZnGeP2 yog pom tseeb: siv lead ua rotation yog tsis tas yuav tsum tau mus cuag wavelength tuning. , ib qho tsuas yog yuav tsum tau kho lub wavelength ntawm ib qho kev sib xyaw beam nyob rau hauv ib qho bandwidth ntawm nqaim li 15.3 nm.
Rau cov ntsiab lus
Kev hloov dua siab tshiab ntawm 0.1% kuj yog qhov siab tshaj plaws puas tau ua tiav rau lub ntsiav tshuaj siv lub tshuab ua lag luam-muaj laser raws li lub twj tso kua mis.Qhov tsuas yog THz uas tuaj yeem sib tw nrog GaSe THz qhov chaw yog lub laser dawb-electron, uas yog qhov loj heev. thiab siv hluav taws xob loj loj.Tsis tas li ntawd, qhov tso zis wavelengths ntawm qhov THz qhov chaw tuaj yeem hloov kho nyob rau hauv ntau qhov dav, tsis zoo li quantum cascade lasers txhua qhov tuaj yeem tsim ib lub wavelength ruaj khov. Yog li ntawd, qee cov ntawv thov uas tuaj yeem paub siv dav-tunable monochromatic THz qhov chaw yuav tsis yog. ua tau yog vam khom rau subpicosecond TSH pulses los yog quantum cascade lasers xwb.
