    Technical parameters

    LBO (Lithium Triborate - LiB3O5) ndiyo inonyanya kushandiswa zvinhu zveSecond Harmonic Generation (SHG) ye1064nm high power lasers (seinotsiva KTP) uye Sum Frequency Generation (SFG) ye1064nm laser sosi yekuwana UV mwenje pa355nm. .
    LBO chikamu chinofananidzwa neSHG uye THG yeNd: YAG uye Nd: YLF lasers, uchishandisa chero mhando I kana Type II kusangana.Kune iyo SHG patembiricha yekamuri, mhando yechikamu chekufananidza inogona kusvikwa uye ine yakanyanya kushanda SHG coefficient muprincipal XY uye XZ ndege muhupamhi hwewavelength kubva pa551nm kusvika 2600nm.SHG shanduko inoshanda yeanopfuura makumi manomwe muzana ekupuruzira uye 30% ye cw Nd: YAG lasers, uye THG shanduko inoshanda pamusoro pemakumi matanhatu% yepulse Nd: YAG laser yakaonekwa.
    LBO yakanakisa NLO kristaro yeOPOs uye OPAs ine yakawandisa inobatika yavelength renji uye masimba akakwira.Aya OPO neOPA ayo anopombwa neSHG neTHG yeNd:YAG laser uye XeCl excimer laser pa308nm yakataurwa.Iwo akasarudzika zvimiro zverudzi I uye mhando II chikamu chinofananidzwa pamwe neNCPM inosiya kamuri hombe mukutsvagisa uye mashandisirwo eLBO's OPO neOPA.
    Zvakanakira:
    • Kujeka kwakakura kubva pa160nm kusvika ku2600nm;
    • High optical homogeneity (δn≈10-6 / cm) uye kusununguka kwekubatanidzwa;
    • Yakakura yakati wandei inoshanda SHG coefficient (inopeta katatu iyo yeKDP);
    • High kukuvadza chikumbaridzo;
    • Wide kubvuma angle uye duku kufamba-kure;
    • Nyora I uye nyora II isiri-yakakosha chikamu chekufananidza (NCPM) mune yakakura wavelength renji;
    • Spectral NCPM pedyo ne1300nm.
    Applications:
    • Kupfuura 480mW kubuda pa395nm kunogadzirwa nefrequency kupeta kaviri 2W mode-yakakiiwa Ti:Sapphire laser (<2ps, 82MHz).Iyo wavelength renji ye700-900nm yakafukidzwa ne5x3x8mm3 LBO crystal.
    • Pamusoro pe80W yakasvibirira yakasvibirira inowanikwa neSHG yeQ-switched Nd: YAG laser mumhando II 18mm yakareba LBO crystal.
    • Kupeta kaviri kwe diode inopomba Nd:YLF laser (>500μJ @ 1047nm,<7ns, 0-10KHz) inosvika pamusoro pe40% kutendeuka kushanda zvakanaka mu9mm yakareba LBO crystal.
    • Iyo VUV yakabuda pa187.7 nm inowanikwa ne sum-frequency generation.
    • 2mJ / pulse diffraction-limited beam pa 355nm inowanikwa ne intracavity frequency katatu Q-switched Nd: YAG laser.
    • Kuchinja kwepamusoro-soro uye 540-1030nm tunable wavelength range yakawanikwa neOPO yakapomba pa355nm.
    • Type I OPA yakapomba pa 355nm ine pombi-to-signal simba rekushandura simba re30% yakataurwa.
    • Type II NCPM OPO yakapombwa neXeCl excimer laser pa 308nm yakawana 16.5% shanduko inoshanda, uye pakati nepakati tunable wavelength siyana inogona kuwanikwa nekusiyana kwekupomba uye tembiricha tuning.
    • Nekushandisa nzira yeNCPM, mhando yeI OPA yakapombwa neSHG yeNd:YAG laser pa532nm yakaonekwawo kuti ivhare hupamhi hwekuturika kubva pa750nm kusvika 1800nm ​​netembiricha yekugadzira kubva pa106.5℃ kusvika 148.5℃.
    • Nekushandisa mhando II NCPM LBO se optical parametric jenareta (OPG) uye mhando I yakakosha phase-inofananidzwa neBBO seOPA, nhete mutsara (0.15nm) uye yakakwirira-ku-signal simba rekushandura simba (32.7%) yakawanikwa yakawanikwa. kana ichipombwa ne4.8mJ, 30ps laser pa354.7nm.Wavelength tuning kubva pa482.6nm kusvika 415.9nm yakavharwa kungave nekuwedzera tembiricha yeLBO kana nekutenderera BBO.
