ʻO ka picosecond ikaika 10.2-µm pulses i hana ʻia i loko o kahi aniani BGGSe no ke kanu ʻana ʻole o nā mea hoʻonui CO2 papa terawatt.
Hōʻike mākou i ka mea a mākou i manaʻoʻiʻo ai he ala hou i ka picosecond 10.2-μm pulse generation e pili ana i ka hui ʻole o ka subnanosecond single-frequency 1338-nm pulses a me ka broadband 1540-nm chirped pulses i loko o kahi aniani BGGSe a ukali ʻia e kahi compressor grating no ke kumu. o ka kanu ʻana i nā mea hoʻonui CO2 mana kiʻekiʻe.Hiki ke loaʻa mau ka ikehu o ka 10.2-μm pulses ma mua o 60 μJ me 3.4% -rms fluctuation.ʻO ke ana lōʻihi o ka pulse pana hoʻokahi, hana ʻia e Kerr polarization rotat...

ʻOi aku ka maikaʻi o ka octave-spanning lōʻihi hawewe infrared hanauna me ka 74% quantum pono ma kahi χ(2) alakaʻi nalu.
Ma kahi kahua alakaʻi nalu e pili ana i ZnGeP2, hoʻokumu ʻia kahi spectrum octavespanning e uhi ana i ka 5-11 μm ma o ka optical parametric generation (OPG).Loaʻa ka pono hoʻololi quantum o 74% ma ke ʻano he moʻolelo hou ma LWIR hoʻokahi-pass parametric kaʻina hana.Ua ana ʻia ka ikehu paepae e like me ~616 pJ, hoʻemi ʻia ma mua o ka 1-kaupapa o ka nui e like me nā MIR OPG i loko o ka media nui.Hiki ke hoʻonui ʻia kā mākou prototype micro-waveguide platform i nā χ(2) birefringence crystals a hoʻoulu hou mai ...

ʻOi aku ka maikaʻi ma mua o 60% Nd:YAG transparent ceramic laser me ka hopena haʻahaʻa haʻahaʻa
Ma ʻaneʻi, ua noiʻi ʻia ka hopena o ka attenuation a me ka hoʻonui ʻana i ka hana laser o Nd:YAG transparent ceramics.Ke hoʻohana nei i ka 0.6 at.% Nd:YAG ceramic koʻokoʻo me 3 mm anawaena a me 65 mm lōʻihi, ka scattering coefficient a me absorption coefficient ma 1064 nm ua ana ia he 0.0001 cm-1 a me 0.0017 cm-1.No ka 808 nm ʻaoʻao-pumped laser hoʻokolohua, ua loaʻa ka mana hoʻopuka awelika o 44.9 W me ka hoʻololi hoʻololi optical-to-optical o 26.4%, ua aneane like me ka ...

ʻO ka ikaika Pulse Kiʻekiʻe, ʻO ka Laina Line Narrow 6.45 µm mai kahi Optical Parametric Oscillator ma BaGa4Se7 Crystal
Hōʻike kēia pepa i ka ikehu pulse kiʻekiʻe, ka laula laina haiki, ka laser mid-infrared (MIR) ma 6.45 µm, ma muli o kahi BaGa4Se7 (BGSe) crystal optical parametric oscillator (OPO) i puhi ʻia e 1.064 µm laser.ʻO ka ikehu pulse kiʻekiʻe ma 6.45 µm a hiki i ka 1.23 mJ, me ka laula pulse o 24.3 ns a me ka helu hou ʻana o 10 Hz, e pili ana i ka hoʻololi ʻana o ka optical-optical o 2.1%, mai ka kukui pump 1.064 µm a i ka māmā palaualelo 6.45 µm.ʻO ka laina laina māmā palaualelo ma kahi o 6.8 nm. I kēia manawa, helu pololei mākou ...

43 W, 7 ns ka lōʻihi o ka pulse mau, kiʻekiʻe-repetition-rate langasite cavity-hoʻolei ʻia Ho: YAG laser a me kona hoʻohana ʻana i waena o nā ZGP OPOs infrared.
Ma kēia pepa, hōʻike mākou i kahi langasite (LGS) electro-optic Ho: YAG cavity-dumped laser e kāohi ana i ka loaʻa ʻana o ka hilinaʻi o ka lōʻihi o ka pulse i nā lasers Q-switched.Ua loaʻa ka lōʻihi o ka pulse mau o 7.2 ns ma ka helu hou ʻana o 100 kHz.ʻO ka pōmaikaʻi mai ke aniani LGS ʻaʻohe hopena koʻikoʻi o ka piezoelectric ring hopena a me ka depolarization thermally induced, ua hoʻokō ʻia kahi kaʻaahi pulse paʻa ma ka mana hoʻopuka o 43 W. No ka manawa mua, ka noi ʻana o ka laser cavity-dumped i mi ...
