LBO Crystal

ʻO LBO (Lithium Triborate - LiB3O5) ka mea kaulana loa no ka lua Harmonic Generation (SHG) o 1064nm kiʻekiʻe mana lasers (ma ke ʻano he KTP) a me Sum Frequency Generation (SFG) o 1064nm laser kumu e hoʻokō ai i ke kukui UV ma 355nm .
Hiki ke hoʻohālikelike ʻia ʻo LBO no ka SHG a me THG o Nd:YAG a me Nd:YLF lasers, me ka hoʻohana ʻana i ka pilina ʻano I a i ʻole type II.No ka SHG ma ka lumi wela, hiki ke loaʻa i ke ʻano I phase matching a loaʻa ka helu SHG kūpono loa i nā mokulele XY a me XZ ma kahi ākea ākea mai 551nm a hiki i 2600nm.ʻOi aku ka maikaʻi o ka hoʻololi ʻana o SHG ma mua o 70% no ka pulse a me 30% no cw Nd:YAG lasers, a me THG hoʻololi ʻoi aku ma luna o 60% no ka pulse Nd:YAG laser i nānā ʻia.
ʻO LBO kahi aniani NLO maikaʻi loa no nā OPO a me nā OPA me ka laulā hawewe ākea ākea a me nā mana kiʻekiʻe.Ua hōʻike ʻia kēia mau OPO a me OPA e ka SHG a me THG o Nd: YAG laser a me XeCl excimer laser ma 308nm.ʻO nā waiwai kūʻokoʻa o ke ʻano I a me ke ʻano II e like me ka NCPM e waiho i kahi lumi nui i ka noiʻi a me nā noi o LBO's OPO a me OPA.
Pono:
• Ka laulā ākea ākea mai 160nm a 2600nm;
• Ka homogeneity optical kiʻekiʻe (δn≈10-6 / cm) a me ka ʻole o ka hoʻokomo ʻana;
• ʻOi aku ka nui o ka helu SHG kūpono (e pili ana i ʻekolu manawa i ko KDP);
• ka paepae pōʻino kiʻekiʻe;
• Ke kihi ākea ākea a me ka hele wāwae liʻiliʻi;
• Type I a me type II non-critical phase matching (NCPM) ma kahi laula hawewe ākea;
• Spectral NCPM kokoke i 1300nm.
Nā noi:
• ʻOi aku ma mua o 480mW puka ma 395nm i hana ʻia e ka pinepine pālua ʻana i kahi 2W mode-locked Ti: Sapphire laser (<2ps, 82MHz).Ua uhi ʻia ka laulā nalu o 700-900nm e kahi aniani 5x3x8mm3 LBO.
• Loaʻa ma luna o 80W hua'ōmaʻomaʻo e SHG o kahi Q-switched Nd:YAG laser ma ke ʻano II 18mm lōʻihi LBO kristal.
• 'O ke alapine o ka palua o ka diode pumped Nd: YLF laser (> 500μJ @ 1047nm, <7ns, 0-10KHz) hiki aku ma luna o 40% hoʻololi pono i loko o ka 9mm lōʻihi LBO kristal.
• Loaʻa ka VUV puka ma 187.7 nm e ka hoʻonui ʻana i ka huina-frequency.
• Loaʻa ka 2mJ/pulse diffraction-limited beam ma 355nm ma ka intracavity frequency tripling a Q-switched Nd:YAG laser.
• Ua loa'a mai ka pono ho'ololi holo'oko'a ki'eki'e a me 540-1030nm ka lō'ihi o ka hawewe tunable me ka OPO i ho'omo 'ia ma 355nm.
• Type I OPA pumped ma 355nm me ka pump-to-signal hoʻololi ikehu pono o 30% ua hōʻike 'ia.
• Type II NCPM OPO pumped by XeCl excimer laser at 308nm ua loaʻa iā 16.5% ka hoʻololi ʻana i ka maikaʻi, a hiki ke loaʻa nā pae lōʻihi haʻahaʻa haʻahaʻa me nā kumu pumping like ʻole a me ke kani wela.
• Ma ka hoʻohana ʻana i ka ʻenehana NCPM, ua ʻike pū ʻia ke ʻano I OPA i puhi ʻia e ka SHG o kahi laser Nd:YAG ma 532nm e uhi i kahi ākea tunable mai 750nm a 1800nm ​​e ka hoʻoponopono ʻana i ka mahana mai 106.5 ℃ a 148.5 ℃.
• Ma ka hoʻohana ʻana i ke ʻano II NCPM LBO ma ke ʻano he optical parametric generator (OPG) a me ka type I critical phase-matched BBO ma ke ʻano he OPA, ua loaʻa ka laina laina haiki (0.15nm) a me ka hoʻololi ʻana i ka ikehu hoʻomāke kiʻekiʻe (32.7%). i ka wā e puhi ʻia e kahi 4.8mJ, 30ps laser ma 354.7nm.Ua uhi ʻia ka lōʻihi o ke kani ʻana o ka nalu mai 482.6nm a 415.9nm ma o ka hoʻonui ʻana i ka mahana o LBO a i ʻole ka hoʻololi ʻana iā BBO.
