Kev hloov pauv zaus
KTP yog thawj zaug qhia raws li NLO siv lead ua rau Nd doped laser tshuab nrog kev hloov pauv siab. Raws li qee qhov xwm txheej, kev hloov pauv kev ua tau zoo tau tshaj tawm rau 80%, uas tawm ntawm lwm cov NLO crystals nyob deb.
Tsis ntev los no, nrog rau kev txhim kho ntawm laser diodes, KTP tau dav siv los ua SHG li hauv diode pumped Nd: YVO4 khoom laser tshuab kom tso tawm ntsuab laser, thiab kuj ua rau lub laser system compact heev.
KTP Rau OPA, OPO Applications
Ntxiv rau nws txoj kev siv dav siv ntau zaus hauv Nd-doped laser tshuab rau cov zis ntsuab / Liab, KTP kuj yog ib qho tseem ceeb tshaj plaws nyob rau hauv parametric qhov chaw rau tunable tso zis los ntawm pom (600nm) mus rau nruab nrab-IR (4500nm) vim qhov muaj koob meej ntawm nws cov khoom siv, qhov tseem ceeb thiab qhov sib haum xeeb thib ob ntawm Nd:YAG lossis Nd:YLF lasers.
Ib qho ntawm cov kev siv tseem ceeb tshaj plaws yog qhov tsis tseem ceeb theem-match (NCPM) KTP OPO / OPA pumped los ntawm cov tunable lasers kom tau txais kev hloov pauv siab. thiab milli-watt nruab nrab hwj chim theem nyob rau hauv ob qho tib si teeb liab thiab idler outputs.
Pumped los ntawm Nd-doped lasers, KTP OPO tau tshaj 66% conversion efficiency rau down-conversion los ntawm 1060nm rau 2120nm.
