Mphamvu za picosecond 10.2-µm zopangidwa mu kristalo wa BGGSe kuti mubzale mbewu zopanda terawatt-class CO2 amplifiers
Tikuwonetsa zomwe timakhulupirira kuti ndi njira yatsopano yopangira mphamvu ya picosecond 10.2-μm kutengera kusakanikirana kosagwirizana kwa subnanosecond single-frequency 1338-nm pulses ndi burodibandi 1540-nm chirped pulses mu BGGSe kristalo yotsatiridwa ndi grating compressor pa cholinga. zokulitsa mphamvu za CO2 amplifiers.Mphamvu ya 10.2-μm pulses yoposa 60 μJ ndi 3.4%-rms kusinthasintha imatha kupezeka nthawi zonse.Muyezo wanthawi ya kugunda kamodzi, kochitidwa ndi Kerr polarization rotat...

Mbadwo wowoneka bwino wa octave wotalikirapo wautali wautali wokhala ndi 74% quantum bwino mu χ(2) waveguide
Papulatifomu yochokera ku ZnGeP2 yochokera ku waveguide, mawonekedwe a octavespanning ophimba 5-11 μm amapangidwa kudzera mumtundu wa optical parametric generation (OPG).Kusintha kwachulukidwe kwa 74% monga mbiri yatsopano mu LWIR single-pass parametric process imatheka.Mphamvu ya pakhomo imayesedwa ngati ~ 616 pJ, kuchepetsedwa ndi kupitirira 1-order of magnitude poyerekeza ndi ma MIR OPGs muzofalitsa zambiri.Pulatifomu yathu ya micro-waveguide imatha kukulitsidwa mpaka χ(2) makhiristo a birefringence ndikuyambitsa zatsopano ...

Kupitilira bwino kwa 60% Nd: YAG yowoneka bwino ya ceramic laser yokhala ndi zotsatira zotsika zotayika
Apa, kutayika kwamphamvu komanso kupititsa patsogolo magwiridwe antchito a laser a Nd:YAG zowonekera zowonekera zidafufuzidwa.Pogwiritsa ntchito 0.6 pa.% Nd: YAG ndodo ya ceramic yokhala ndi 3 mm m'mimba mwake ndi 65 mm kutalika, coefficient yomwaza ndi kuyamwa kwa 1064 nm inayesedwa kukhala 0.0001 cm-1 ndi 0.0017 cm-1, motsatira.Pakuyesa kwa laser ya 808 nm side-pumped laser, mphamvu yapakati ya 44.9 W idakwaniritsidwa ndikusintha kwamphamvu kwa 26.4%, komwe kunali kofanana ndi ...

High Pulse Energy, Narrow Linewidth 6.45 µm kuchokera ku Optical Parametric Oscillator mu BaGa4Se7 Crystal
Pepalali limapereka mphamvu yothamanga kwambiri, yopapatiza, yapakati pa infrared (MIR) laserat 6.45 µm, kutengera BaGa4Se7 (BGSe) crystal optical parametric oscillator (OPO) yopopa ndi laser 1.064 µm.Mphamvu yothamanga kwambiri pa 6.45 µm inali mpaka 1.23 mJ, ndi kugunda kwapakati kwa 24.3 ns ndi kubwerezabwereza kwa 10 Hz, yofanana ndi kutembenuka kwa kuwala kwa kuwala kwa 2.1%, kuchokera ku kuwala kwa mpope 1.064 µm mpaka 6.45 6.45.Mzere wopepuka wa idler unali pafupifupi 6.8 nm.Panthawiyi, timawerengera molondola ...

43 W, 7 ns nthawi zonse kugunda kwamphamvu, kubwereza-bwereza-kubwereza kwa langasite patsekeke-kutayidwa Ho:YAG laser ndi appilcation ake pakati infrared ZGP OPOs
Mu pepalali, tikuwonetsa laser ya langasite (LGS) electro-optic Ho:YAG cavity-dumped laser yomwe imapondereza kudalira kudalira kwa kugunda kwa nthawi mu ma lasers osinthika a Q.Kuthamanga kosalekeza kwa 7.2 ns kunapezedwa pa mlingo wobwerezabwereza wa 100 kHz.Kupindula ndi kristalo wa LGS kulibe ring reverse piezoelectric ring effect komanso depolarization yochititsa thermally, sitima yokhazikika yothamanga inapezedwa ndi mphamvu yotulutsa 43 W. Kwa nthawi yoyamba, kugwiritsa ntchito laser yotayidwa pami...
