ZnGeP2 - Yakazara Infrared Nonlinear Optics
Product Description
Nekuda kwezvivakwa izvi zvakasarudzika, inozivikanwa seimwe yeanonyanya kuvimbisa zvinhu zveasina mutsara optical application. ZnGeP2 inogona kugadzira 3-5 μm inoenderera mberi tunable laser kunze yakaiswa kuburikidza neiyo optical parametric oscillation (OPO) tekinoroji. MaLaser, anoshanda mumhepo yekufambisa hwindo re3–5 μm akakosha zvikuru kune akawanda maapplication, senge infrared counter measure, chemikari kutarisa, midziyo yekurapa, uye kure kure kunzwa.
Tinogona kupa yakakwira optical mhando ZnGeP2 ine yakanyanya kuderera absorption coefficient α <0.05 cm-1 (papombi wavelengths 2.0-2.1 µm), iyo inogona kushandiswa kugadzira yepakati-infrared tunable laser ine hunyanzvi hwepamusoro kuburikidza neOPO kana OPA maitiro.
Kugona Kwedu
Dynamic Temperature Field Technology yakagadzirwa uye yakashandiswa kugadzira ZnGeP2 polycrystalline. Kuburikidza neiyi tekinoroji, kupfuura 500g yakakwirira kuchena ZnGeP2 polycrystalline ine zviyo zvakakura yakagadziriswa mukumhanya kumwe.
Horizontal Gradient Freeze nzira yakasanganiswa neDirectional Necking Technology (iyo inogona kuderedza density yekusagadzikana zvakanaka) yakashandiswa zvakabudirira mukukura kwemhando yepamusoro ZnGeP2.
ZnGeP2 yekirogiramu-yepamusoro-soro ine dhayamita hukuru pasi rose (Φ55 mm) yakabudirira kukura nenzira yeVertical Gradient Freeze.
Iko kushata kwepamusoro uye kupfava kwemidziyo yekristaro, isingasviki 5Å uye 1/8λ zvichiteerana, yakawanikwa netekinoroji yedu yepamusoro yekurapa tekinoroji.
Kutsauka kwekona kwekupedzisira kwemidziyo yekristaro ishoma pane 0.1 dhigirii nekuda kwekushandiswa kweiyo chaiyo yekutarisa uye chaiyo yekucheka matekiniki.
Zvishandiso zvine mashandiro akanaka kwazvo zvakawanikwa nekuda kwehupamhi hwemhando yemakristaro uye yepamusoro-yepamusoro-soro tekinoroji yekugadzira tekinoroji (Iyo 3-5μm yepakati-infrared tunable laser yakagadzirwa nekugona kushandurwa kunopfuura 56% kana yapombwa nechiedza che2μm. tsime).
Boka redu rekutsvagisa, kuburikidza nekuenderera mberi kwekuongorora uye hunyanzvi hwekuvandudza tekinoroji, rakabudirira kubata tekinoroji yekugadzirwa kwepamusoro-kuchena ZnGeP2 polycrystalline, tekinoroji yekukura yehukuru hukuru uye yemhando yepamusoro ZnGeP2 uye kutariswa kwekristaro uye yakakwirira-chaiyo yekugadzirisa tekinoroji; inogona kupa ZnGeP2 zvishandiso uye yekutanga se-yakakura makristasi muhukuru hwakafanana nehupamhi hwepamusoro, yakaderera kunyura coefficient, kugadzikana kwakanaka, uye yakanyanya kutendeuka kushanda zvakanaka. Panguva imwecheteyo, isu takagadzira seti yese yekristaro performance test platform inoita kuti tive nekwaniso yekupa masevhisi ekuyedza ekristaro kune vatengi.
Applications
● Chechipiri, chechitatu, uye chechina harmonic chizvarwa che CO2-laser
● Optical parametric generation nekupomba pawavelength ye2.0 µm
● Chechipiri harmonic chizvarwa cheCO-laser
● Kugadzira yakabatana mwaranzi mu submillimeterrange kubva 70.0 µm kusvika 1000 µm
● Chizvarwa chezvakasanganiswa mafrequency eCO2- neCO-laser radiation uye mamwe lasers ari kushanda munzvimbo yekristaro yakajeka.
