KTP — Fa'aluaina Fa'asao O Lasers Nd:yag Ma Isi Lasers Nd-doped
Fa'amatalaga o oloa
O le KTP o le mea e masani ona faʻaaogaina mo le faaluaina o Nd: YAG lasers ma isi Nd-doped lasers, aemaise ile maualalo poʻo le feololo le malosi.
Tulaga lelei
● Fa'aliliuga fa'asolosolo lelei (1064nm SHG fa'aliliuga lelei e tusa ma le 80%)
● Lapopo'a fa'atasi fa'atasi (15 fa'apei o le KDP)
● Alalaupapa fa'alava fa'alava ma le la'ititi la'ititi savali
● Lautele vevela ma faʻapipiʻi faʻasalalau
● maualuga le vevela conductivity (2 taimi o le tioata BNN)
● E leai se susu
● Fa'asao le fetaui pito maualalo
● Super-poiila mata opitika
● Leai se pala i lalo ole 900°C
● Manuia mautu
● Tau maualalo pe a faatusatusa i le BBO ma le LBO
Talosaga
● Fa'aluaina Fa'atele (SHG) o Nd-doped Lasers mo le mea lanu meamata/mumu
● Fa'afefiloi Fa'atele (SFM) o le Nd Laser ma le Diode Laser mo le Blue Output
● Punavai Fa'ata'oto (OPG, OPA ma OPO) mo le 0.6mm-4.5mm le Fa'atala Fa'alogo.
● Fa'atonu Fa'atonu (EO) Fa'aeletise, Su'e Mata, ma Fa'atasiga Fa'atonu
● Ta'iala Galue mata'utia mo masini NLO ma EO fa'atasi
Fa'aliliuga Faatele
KTP na muamua faʻafeiloaʻi e pei o le NLO tioata mo Nd doped laser system ma maualuga le faʻaliliuga lelei. I lalo o nisi tulaga, o le suiga o le liua na lipotia i le 80%, lea e tuua ai isi tioata NLO mamao i tua.
Talu ai nei, faʻatasi ai ma le atinaʻeina o le laser diodes, KTP o loʻo faʻaaogaina lautele e pei o le SHG masini i le diode pamu Nd: YVO4 faʻapipiʻi leisa malosi e gaosia le laser lanumeamata, ma ia faʻapipiʻiina foi le laser system.
KTP mo OPA, OPO Talosaga
I le faʻaopoopoga i lona faʻaaogaina lautele e pei o se masini faʻaluaina i le Nd-doped laser system mo le Green/Red output, KTP o se tasi lea o tioata sili ona taua i puna faʻataʻitaʻi mo galuega faʻalogo mai le vaʻaia (600nm) i le ogatotonu o le IR (4500nm) ona o le lauiloa o ona puna puna, le faavae ma lona lua harmonic a Nd: YAG po Nd: YLF lasers.
O se tasi o talosaga e sili ona aoga o le vaega e le taua tele-faafetaui (NCPM) KTP OPO/OPA pamu e le lasers tunable e maua ai le maualuga o le liua lelei.KTP OPO taunuuga i le mautu galuega faatino faifai pea o femto-lua pulse o le 108 Hz toe fai fua faatatau. ma le milli-watt averesi le maualuga o le mana i fa'ailo ma galuega fa'ata'ita'i.
O le pamuina e Nd-doped lasers, KTP OPO ua maua i luga atu o le 66% le lelei o le liua mo lalo-faaliliu mai le 1060nm i le 2120nm.
Electro-Optical Modulators
KTP tioata e mafai ona faʻaaogaina e fai ma faʻaogaina eletise eletise. Mo nisi fa'amatalaga, fa'amolemole fa'afeso'ota'i a matou inisinia fa'atau.
