Imilinganiselo yobugcisa

I-LBO (i-Lithium Triborate - i-LiB3O5) ngoku yeyona nto isetyenziswa kakhulu kwi-Second Harmonic Generation (SHG) ye-1064nm i-laser yamandla aphezulu (njengendawo ebambela i-KTP) kunye ne-Sum Frequency Generation (SFG) ye-1064nm yomthombo we-laser ukufezekisa ukukhanya kwe-UV kwi-355nm .
I-LBO sisigaba esihambelana ne-SHG kunye ne-THG ye-Nd: YAG kunye ne-Nd: ii-lasers ze-YLF, usebenzisa nokuba yi-intlobo ye-I okanye i-II intsebenziswano.Kwi-SHG kwiqondo lobushushu begumbi, uhlobo lokuthelekisa lwesigaba soku-I lunokufikelelwa kwaye lunowona mlinganiso uphezulu we-SHG osebenzayo kwinqununu i-XY kunye neenqwelo-moya ze-XZ kuluhlu olubanzi lwamaza ukusuka kwi-551nm ukuya malunga ne-2600nm.Ukuphumelela kokuguqulwa kwe-SHG okungaphezulu kwe-70% ye-pulse kunye ne-30% ye-cw Nd: ii-lasers ze-YAG, kunye nokusebenza kakuhle kokuguqulwa kwe-THG ngaphezu kwe-60% ye-pulse Nd: YAG laser iye yabonwa.
I-LBO yikristale egqwesileyo ye-NLO yee-OPO kunye nee-OPA ezinoluhlu olubanzi lwe-wavelength kunye namandla aphezulu.Ezi OPO kunye ne-OPA ezimpontshwa yi-SHG kunye ne-THG ye-Nd: YAG laser kunye ne-XeCl excimer laser kwi-308nm zixeliwe.Iimpawu ezikhethekileyo zohlobo lwe-I kunye nohlobo lwe-II oluhambelana nesigaba kunye ne-NCPM ishiya igumbi elikhulu kuphando kunye nokusetyenziswa kwe-LBO ye-OPO kunye ne-OPA.
Izinto eziluncedo:
• Uluhlu olubanzi lokubonisa elubala ukusuka kwi-160nm ukuya kwi-2600nm;
• I-homogeneity ephezulu ye-optical (δn≈10-6 / cm) kunye nokukhululeka kokubandakanywa;
• Ngokuthelekisa ubukhulu be-SHG i-coefficient (malunga nokuphinda kathathu kwe-KDP);
• Umda womonakalo omkhulu;
• I-engile yokwamkelwa ebanzi kunye nokuhamba kancinci;
• Uhlobo lwe-I kunye nohlobo lwe-II lwesigaba esingabalulekanga (NCPM) kuluhlu olubanzi lwamaza;
• I-Spectral NCPM kufutshane ne-1300nm.
Usetyenziso:
• Ngaphezulu kwe-480mW imveliso kwi-395nm iveliswa ngokuphindaphinda kabini i-2W yemowudi etshixiwe i-Ti: i-laser ye-Sapphire (<2ps, 82MHz).Uluhlu lwamaza angama-700-900nm lugutyungelwe yikristale ye-LBO ye-5x3x8mm3.
• Ngaphezulu kwe-80W imveliso eluhlaza ifunyenwe yi-SHG ye-Q-switched Nd: YAG laser kuhlobo lwe-II 18mm ubude be-crystal LBO.
• Ukuphinda-phinda kabini kwe-diode impompo ye-laser Nd:YLF (>500μJ @ 1047nm,<7ns, 0-10KHz) ifikelela ngaphezulu kwe-40% yoguqulo olusebenzayo kwikristale ye-9mm ende ye-LBO.
• Imveliso yeVUV kwi-187.7 nm ifunyanwa ngokwenziwa kwe-sum-frequency.
• I-2mJ / i-pulse diffraction-limited beam kwi-355nm ifunyenwe nge-intracavity frequency tripling i-Q-switched Nd: YAG laser.
• Uguqulo olusulungekileyo olufanelekileyo kunye ne-540-1030nm yoluhlu lwamaza okulinganisa lufunyenwe nge-OPO emponthwe kwi-355nm.
• Udidi lwe-OPA lwe-I olumponthwe nge-355nm ngempompo ukuya kwi-signal yoguqulo lwamandla oluyi-30% luxeliwe.
• Uhlobo lwe-II lwe-NCPM i-OPO emponthwe nge-laser ye-XeCl ye-excimer kwi-308nm ifikelele kwi-16.5% yoguqulo olusebenzayo, kunye noluhlu lwe-wavelength oluphakathi lunokufunyanwa ngemithombo eyahlukeneyo yokumpompa kunye nokulungiswa kobushushu.
• Ngokusebenzisa ubuchule be-NCPM, uhlobo lwe-OPA yoku-I emponthwe nge-SHG ye-laser ye-Nd:YAG kwi-532nm nayo yaqatshelwa ukugquma uluhlu olubanzi oluqhutywayo ukusuka kwi-750nm ukuya kwi-1800nm ngokulungiswa kobushushu ukusuka kwi-106.5℃ ukuya kwi-148.5℃.
• Ngokusebenzisa uhlobo lwe-II NCPM LBO njengejenereyitha yeparametric yokukhanya (OPG) kunye nohlobo lwe-BBO ehambelana nesigaba esibalulekileyo njenge-OPA, ububanzi obumxinwa (0.15nm) kunye noguqulo lwamandla olumpompe ukuya kumqondiso (32.7%) lufunyenwe. xa ifakwe i-4.8mJ, i-30ps laser kwi-354.7nm.Uluhlu lwe-wavelength tuning ukusuka kwi-482.6nm ukuya kwi-415.9nm lugqunywe ngokunyusa ubushushu be-LBO okanye ngokujikeleza kwe-BBO.
