Amakristalu e-GaSe

Kusetshenziswa ikristalu ye-GaSe ubude begagasi obuphumayo bushunwe kububanzi obusuka ku-58.2 µm ukuya ku-3540 µm (kusuka ku-172 cm-1 ukuya ku-2.82 cm-1) ngamandla aphakeme afinyelela ku-209 W. Okuthuthukisiwe kakhulu kwenziwe emandleni okukhiphayo ale THz. umthombo kusuka ku-209 W kuya ku-389 W.

Amakristalu e-ZnGeP2

Ngakolunye uhlangothi, ngokusekelwe ku-DFG kukristalu ye-ZnGeP2 ubude beza beza obuphumayo bushunwe kububanzi buka-83.1–1642 µm kanye no-80.2–1416 µm ekucushweni okufanayo kwezigaba ezimbili, ngokulandelanayo.Amandla okukhiphayo afinyelele ku-134 W.

Amakristalu e-GaP

Kusetshenziswa ikristalu ye-GaP ubude begagasi obuphumayo bushunwe kububanzi obungu-71.1−2830 µm kuyilapho amandla aphezulu kakhulu ayengu-15.6 W. Inzuzo yokusebenzisa i-GaP phezu kwe-GaSe ne-ZnGeP2 isobala: ukuzungeziswa kwekristalu akusadingeki ukuze kuzuzwe ukushuna kwe-wavelength. , umuntu udinga nje ukushuna ubude begagasi benduku eyodwa yokuhlanganisa ngaphakathi komkhawulokudonsa owumngcingo njengo-15.3 nm.

Ukufingqa

Ukusebenza kahle kokuguqulwa okungu-0.1% nakho kuphakeme kakhulu okwake kwafinyelelwa kusistimu ye-tabletop kusetshenziswa isistimu ye-laser etholakalayo kwezohwebo njengemithombo yephampu.Umthombo we-THz kuphela ongaqhudelana nomthombo we-GaSe THz i-free-electron laser, enamandla kakhulu. futhi idla amandla amakhulu kagesi.Ngaphezu kwalokho, ubude bamaza okukhiphayo bemithombo yaleTHz ingashunwa kububanzi obubanzi ngokwedlulele, ngokungafani namalaser e-quantum cascade ngayinye yawo engakwazi ukukhiqiza ubude begagasi obugxilile. kungenzeka uma uncike kuma-subpicosecond THz pulses noma ama-quantum cascade lasers esikhundleni salokho.
