    Vhidhiyo

    Potassium Titanyl Phosphate (KTiOPO4 kana KTP) KTP ndiyo inonyanyo shandiswa zvinhu zvekuwandisa zvakapetwa zveNd: YAG uye mamwe maNd-doped lasers, kunyanya kana kuwanda kwesimba kuri padanho repasi kana repakati. Kusvika pari zvino, yakawedzera uye yepakati-mhango frequency yakapetwa kaviri Nd: lasers vachishandisa KTP vakave inodiwa yekupomba sosi yeinooneka dhayi lasers uye inogadziriswa Ti: Sapphire lasers pamwe neyavo ma amplifaya. Izvo zvakare zvinobatsira manyoro masosi eakawanda ekutsvagisa uye indasitiri kunyorera.
    KTP irikushandiswazve kusanganisa kwemukati me0.81µm diode uye 1.064µm Nd: YAG laser kuti iite mwenje webhuruu uye intracavity SHG yeNd: YAG kana Nd: YAP lasers pa1.3µm kuburitsa mwenje mutsvuku.
    Kuwedzera kune yakasarudzika NLO maficha, KTP zvakare ine anovimbisa EO uye dielectric zvivakwa izvo zvakaenzana neLiNbO3. Izvi zvinobatsira zvivakwa zvinoita KTP inobatsira zvakanyanya kune akasiyana EO zvishandiso. 
    KTP inotarisirwa kutsiva LiNbO3 kristaro mune yakawandisa vhoriyamu kushandiswa kweEO modulators, apo zvimwe zvinokodzera zveKTP zvinosanganiswa kuve account, senge yakanyanya kukuvara chikumbaridzo, yakafara optical bandwidth (> 15GHZ), kupisa uye kugadzikana kwemagetsi, uye kurasikirwa kwakaderera, nezvimwe. .
    Huru Zvimiro zveKTP Makristasi:
    ● Kushanda kwakaringana kushandurwa (1064nm SHG kushandurwa kwekushanda kuri nezve 80%)
    ● Makuru asina kukwana emagetsi coefficients (ka15 iyo yeKDP)
    ● Wide angular bandwidth uye diki kufamba-kure kona
    ● Kupisa kukuru uye bandwidth yekuratidzira
    ● Yakakwira kupisa kupisa (2 nguva iyo yeBNN kristaro)
    Mafomu:
    ● Frequency Doubling (SHG) yeNd-doped Lasers yeGreen / Tsvuku Yakabuda
    ● Frequency Kusanganisa (SFM) yeNd Laser uye Diode Laser yeBlue Output
    ● Parametric Sources (OPG, OPA uye OPO) ye0.6mm-4.5mm Tunable Output
    ● Electrical Optical (EO) Modulators, Optical Swichi, uye Directional Couplers
    ● Optical Waveguides e Akabatanidzwa NLO uye EO Zvishandiso a = 6.404Å, b = 10.615Å, c = 12.814Å, Z = 8
