Iikristale zeGaSe
Ukusebenzisa i-crystal ye-GaSe i-wavelength ye-output yalungiswa kuluhlu ukusuka kwi-58.2 µm ukuya kwi-3540 µm (ukusuka kwi-172 cm-1 ukuya kwi-2.82 cm-1) ngamandla aphezulu afikelela kwi-209 W. Uphuculo oluphawulekayo lwenziwe kumandla aphumayo ale THz umthombo ukusuka kwi-209 W ukuya kuma-389 W.
Iikristale zeZnGeP2
Kwelinye icala, ngokusekwe kwi-DFG kwikristale ye-ZnGeP2 i-wavelength ephumayo yalungiswa kuluhlu lwe-83.1-1642 µm kunye ne-80.2-1416 µm yolungelelwaniso lwezigaba ezibini ezihambelanayo, ngokulandelelana.
Iikristale ze-GaP
Ukusebenzisa ikristale ye-GaP i-wavelength ephumayo yalungiswa kuluhlu lwe-71.1−2830 µm ngelixa amandla aphezulu aphezulu yayiyi-15.6 W. Inzuzo yokusebenzisa i-GaP phezu kwe-GaSe kunye ne-ZnGeP2 icacile: ukujikeleza kwekristale akusafuneki ukuze kuphunyezwe ukulungiswa kwe-wavelength. , umntu ufuna nje ukujikelisa ubude bomqadi omnye wokuxuba ngaphakathi kwe-bandwidth emxinwa njenge-15.3 nm.
Ukushwankathela
Ukuphumelela kokuguqulwa kwe-0.1% kukwayeyona nto iphezulu eyake yaphunyezwa kwi-tabletop system isebenzisa inkqubo ye-laser ekhoyo ngokurhweba njengemithombo yempompo.Umthombo we-THz kuphela onokukhuphisana nomthombo we-GaSe THz yi-laser ye-electron yamahhala, eninzi kakhulu. kwaye isebenzisa amandla amakhulu ombane.Ngaphaya koko, ubude bamaza bemveliso yale THz mithombo inokulungelelaniswa kuluhlu olubanzi kakhulu, ngokungafaniyo nequantum cascade lasers nganye enokuthi ivelise i-wavelength emiselweyo. Ke ngoko, izicelo ezithile ezinokuthi ziphunyezwe kusetyenziswa imithombo ye-THz evuleleka ngokubanzi-imonochromatic ayinakwenzeka. kunokwenzeka ukuba uthembele kwi-subpicosecond THz pulses okanye i-quantum cascade lasers endaweni yoko.
