KTP - ugboro abụọ nke Nd: yag Lasers na Lasers Nd-doped ndị ọzọ
Nkọwa ngwaahịa
KTP bụ ihe a na-ejikarị eme ihe maka ugboro abụọ nke Nd: YAG lasers na lasers Nd-doped ndị ọzọ, karịsịa na njupụta ike dị ala ma ọ bụ ọkara.
Uru
● Ntugharị ugboro ole na-arụ ọrụ nke ọma (1064nm SHG ntụgharị arụmọrụ bụ ihe dịka 80%)
● Nnukwu ọnụọgụ ngwa anya na-adịghị adị (ugboro 15 nke KDP)
● bandwit n'akuku sara mbara na obere akụkụ-apụ apụ
● Okpomọkụ sara mbara na bandwidth spectral
● Igwe ọkụ dị elu (ugboro abụọ nke BNN kristal)
● Mmiri enweghị mmiri
● Opekempe na-adaghị adaba gradient
● elu-egbu maramara anya elu
● Enweghị ire ere n'okpuru 900°C
● Mechanical kwụsiri ike
● Ọnụ ego dị ala ma e jiri ya tụnyere BBO na LBO
Ngwa
● Ugboro ugboro abụọ (SHG) nke Lasers Nd-doped maka mmepụta Green/Red.
● Ngwakọta ugboro ugboro (SFM) nke Nd Laser na Diode Laser maka mmepụta na-acha anụnụ anụnụ
● Isi mmalite nke Parametric (OPG, OPA na OPO) maka mmepụta 0.6mm-4.5mm Tunable
● Eletriki Optical (EO) Modulators, Optical Switches, and Directional Couplers
● Ntuziaka Wave Optical maka Ngwakọta NLO na EO
Ntugharị ugboro ugboro
Ebu ụzọ weba KTP dị ka kristal NLO maka sistemu laser Nd doped nwere arụmọrụ ntụgharị dị elu.N'okpuru ọnọdụ ụfọdụ, a kọwapụtara arụmọrụ ntụgharị na 80%, nke na-ahapụ kristal NLO ndị ọzọ n'azụ.
Na nso nso a, na mmepe nke laser diodes, KTP na-eji ọtụtụ ebe dị ka SHG ngwaọrụ na diode pumped Nd:YVO4 siri ike laser usoro mmepụta green laser, na-emekwa ka laser usoro nnọọ kọmpat.
KTP Maka OPA, Ngwa OPO
Na mgbakwunye na ojiji ya sara mbara dị ka ngwa ugboro ugboro abụọ na sistemu laser Nd-doped maka mmepụta Green / Red, KTP bụkwa otu n'ime kristal kachasị mkpa na isi mmalite parametric maka mmepụta a na-ahụ anya site na anya (600nm) ruo etiti IR (4500nm). n'ihi ewu ewu nke isi mmalite ya, ihe bụ isi na nkwekọrịta nke abụọ nke Nd: YAG ma ọ bụ Nd:YLF lasers.
Otu n'ime ngwa kachasị baa uru bụ KTP OPO/OPA na-agbapụta site na lasers Tunable iji nweta arụmọrụ ntụgharị dị elu.KTP OPO na-arụpụta nsonaazụ na-aga n'ihu nke femto-second pulse nke 108 Hz repetition rate. na nkezi ọkwa ike milli-watt na ma mgbama ma na-enweghị ọrụ.
N'ịbụ nke lasers Nd-doped na-ebugharị, KTP OPO enwetala n'elu arụmọrụ ntụgharị 66% maka ntụgharị ala site na 1060nm ruo 2120nm.
Electro-Optical Modulators
