I-Picosecond enamandla engu-10.2-µm pulses ekhiqizwe ngekristalu ye-BGGSe ukuze kutshalwe imbewu engaqondile yezikhulisamandla ze-terawatt-class CO2
Sikhombisa esikholelwa ukuthi indlela entsha yokwenza i-picosecond 10.2-μm pulse esebenzayo esekelwe ekuxubeni okungaqondile kwe-subnanosecond single-frequency 1338-nm pulses kanye nama-broadband 1540-nm atshiyozayo ku-crystal ye-BGGSe elandelwa yi-compressor ye-grating ngenjongo. yokutshala izikhulisamandla ze-CO2 ezinamandla amakhulu.Amandla wamapulses angu-10.2-μm adlula u-60 μJ ngokuguquguquka okungu-3.4%-rms angatholakala ngokujwayelekile.Isilinganiso sobude besikhathi sokudubula okukodwa, okwenziwe yi-Kerr polarization rotat...

Isizukulwane se-infrared esifinyelela ubude begagasi elide be-octave esisebenza kahle kakhulu esinokusebenza kahle kwe-quantum okungu-74% ku-χ(2) i-waveguide
Kuplathifomu ye-waveguide esekelwe ku-ZnGeP2, i-octavesspanning spectrum evala u-5–11 μm yenziwa nge-optical parametric generation (OPG).Ukusebenza kahle kokuguqulwa kwe-quantum okungu-74% njengerekhodi elisha kuzinqubo zepharamitha ye-LWIR ye-single-pass kufinyelelwa.Amandla e-threshold akalwa ngokuthi ~ 616 pJ, ancishiswe nge-oda eli-1 lobukhulu uma kuqhathaniswa nalawo e-MIR OPGs kumidiya eyinqwaba.Ingxenyekazi yethu ye-prototype ye-micro-waveguide inganwetshwa kwamanye amakristalu angu-χ(2) futhi iqalise okusha...

Idlula u-60% ukusebenza kahle kwe-Nd:YAG i-ceramic laser esobala enomphumela ophansi wokulahlekelwa kokuthomba
Lapha, umthelela wokulahleka kokuncipha kanye nokuthuthukiswa kokusebenza kwe-laser kwe-Nd:YAG ye-ceramics esobala kuye kwaphenywa.Kusetshenziswa i-0.6 at.% Nd:YAG induku ye-ceramic enobubanzi obungu-3 mm nobude obungu-65 mm, i-coefficient ehlakazayo kanye ne-absorption coefficient ku-1064 nm kukalwe kwaba ngu-0.0001 cm-1 kanye no-0.0017 cm-1, ngokulandelana.Ocwaningweni lwe-laser edonsa eceleni engu-808 nm, amandla aphumayo ayisilinganiso angu-44.9 W afinyelelwe ngokusebenza kahle kokuguqulwa kwe-optical-to-optical okungu-26.4%, okucishe kufane ne...

I-High Pulse Energy, i-Narrow Linewidth 6.45 µm kusukela ku-Oscillator ye-Optical Parametric ku-BaGa4Se7 Crystal
Leli phepha libonisa amandla aphezulu okushaya kwenhliziyo, ububanzi bomugqa obuncane, i-mid-infrared (MIR) laserat 6.45 µm, ngokusekelwe ku-BaGa4Se7 (BGSe) crystal optical parametric oscillator (OPO) empontshwa nge-laser engu-1.064 µm.Amandla okushaya kwenhliziyo aphezulu ku-6.45 µm ayefike ku-1.23 mJ, nobubanzi bepulse obungu-24.3 ns nezinga lokuphindaphinda elingu-10 Hz, elihambisana nempumelelo yokuguqulwa kwe-optical–optical engu-2.1%, ukusuka ekukhanyeni kwephampu okungu-1.064 µm kuya ku-idler light 4.45 µm6.Ububanzi bokukhanya obungenzi lutho babucishe bube ngu-6.8 nm.Okwamanje, sibala ngokunembile...

43 W, 7 ns ubude besikhathi sokushaya kwenhliziyo okungaguquki, izinga eliphezulu lokuphindaphinda kwe-langasite cavity-lahliwe i-Ho:YAG laser kanye nokusetshenziswa kwayo kuma-ZGP OPOs amaphakathi ne-infrared
Kuleli phepha, sibonisa ilaser ye-langasite (LGS) electro-optic Ho:YAG cavity-dumped laser ecindezela ukuncika kwenzuzo kwesikhathi sokushaya kwenhliziyo kumalaser ashintshiwe nge-Q.Ubude be-pulse obungaguquki obungu-7.2 ns bufinyelelwe ngenani lokuphindaphinda elingu-100 kHz.Ukuzuza kukristalu ye-LGS akunawo umthelela wokuhlehla wendandatho ye-piezoelectric ehlehlayo kanye ne-depolarization ebangelwa ukushisa, isitimela esishayelayo esizinzile sitholwe ngamandla okukhipha angu-43 W. Ngokokuqala ngqa, ukusetshenziswa kwe-laser ye-cavity-dumped in mi...
