Energetic picosecond 10.2-µm pulses generated hauv BGGSe siv lead ua rau nonlinear seeding ntawm terawatt-chav kawm CO2 amplifiers
Peb ua kom pom qhov peb ntseeg tias yog ib txoj hauv kev tshiab rau lub zog picosecond 10.2-μm mem tes tiam raws li kev sib xyaw tsis sib xws ntawm subnanosecond ib zaus 1338-nm pulses thiab broadband 1540-nm chirped pulses hauv BGGse siv lead ua ua raws li lub hom phiaj ntawm kev sib txuas. ntawm seeding high-power CO2 amplifiers.Lub zog ntawm 10.2-μm pulses tshaj 60 μJ nrog 3.4%-rms hloov pauv tuaj yeem tau txais txhua hnub.Kev ntsuas tib lub sijhawm ntsuas pulse, ua los ntawm Kerr polarization rotat ...

Ua tau zoo octave-ntev ntev-ntev infrared tiam nrog 74% quantum efficiency hauv χ(2) waveguide
Hauv ZnGeP2-based waveguide platform, octavespanning spectrum npog 5-11 μm yog tsim los ntawm optical parametric tiam (OPG).Lub quantum conversion efficiency ntawm 74% raws li cov ntaub ntawv tshiab nyob rau hauv LWIR ib leeg-pass parametric txheej txheem yog tiav.Lub zog pib yog ntsuas li ~ 616 pJ, txo los ntawm ntau dua 1-kev txiav txim ntawm qhov loj me piv rau cov MIR OPGs hauv cov xov xwm ntau.Peb cov qauv micro-waveguide platform tuaj yeem txuas ntxiv mus rau lwm qhov χ(2) birefringence crystals thiab ua rau cov tshiab ntawm ...

Tshaj 60% efficiency Nd: YAG pob tshab ceramic laser nrog tsawg attenuation poob nyhuv
Ntawm no, txo qis cov nyhuv thiab kev ua haujlwm ntawm laser ntawm Nd:YAG pob tshab ceramics tau tshawb xyuas.Siv lub 0.6 at.% Nd: YAG ceramic pas nrig nrog 3 hli txoj kab uas hla thiab 65 hli ntev, lub scattering coefficient thiab absorption coefficient ntawm 1064 nm tau ntsuas 0.0001 cm-1 thiab 0.0017 cm-1, feem.Rau 808 nm sab-pumped laser sim, qhov nruab nrab tso zis zog ntawm 44.9 W tau ua tiav nrog kev hloov kho qhov muag-rau-kho qhov muag ntawm 26.4%, uas yog ze li qub nrog th ...

Siab Pulse Zog, Nqaim Linewidth 6.45 µm los ntawm Optical Parametric Oscillator hauv BaGa4Se7 Crystal
Daim ntawv no nthuav tawm lub zog pulse siab, nqaim linewidth, nruab nrab-infrared (MIR) laserat 6.45 µm, raws li BaGa4Se7 (BGSe) siv lead ua optical parametric oscillator (OPO) pumped by1.064 µm laser.Qhov siab tshaj plaws pulse zog ntawm 6.45 µm yog mus txog 1.23 mJ, nrog lub mem tes dav ntawm 24.3 ns thiab rov ua dua tus nqi ntawm 10 Hz, sib haum mus rau qhov kev hloov kho qhov muag-optical efficiency ntawm 2.1%, los ntawm lub teeb lub teeb 1.064 µm mus rau idler lub teeb 6.45 µm.Lub idler lub teeb linewidth yog hais txog 6.8 nm.Meanwhile, peb raug calcu...

43 W, 7 ns tas li mem tes ntev, siab-repetition-rate langasite kab noj hniav-dum Ho:YAG laser thiab nws appilcation nyob rau hauv nruab nrab-infrared ZGP OPOs
Nyob rau hauv daim ntawv no, peb ua qauv qhia ib tug langasite (LGS) electro-optic Ho: YAG kab noj hniav-tso laser uas suppresses qhov nce dependence ntawm mem tes ntev nyob rau hauv Q-hloov lasers.Lub sijhawm tas mus li ntawm cov mem tes ntawm 7.2 ns tau ua tiav ntawm qhov rov ua dua ntawm 100 kHz.Tau txais txiaj ntsig los ntawm LGS siv lead ua tsis muaj qhov cuam tshuam rov qab piezoelectric nplhaib thiab thermally induced depolarization, lub tsheb ciav hlau ruaj khov tau ua tiav ntawm lub zog tso zis ntawm 43 W. Thawj zaug, daim ntawv thov ntawm kab noj hniav-dum laser hauv mi ...
