AgGaSe2 Makristasi - Band Edges Pa0.73 Uye 18 µm
Product Description
Tuning mukati me2.5–12 µm yawanikwa pakupomba neHo:YLF laser pa2.05 µm;pamwe chete neasiri-yakakosha phase matching (NCPM) kushanda mukati me1.9–5.5 µm pakupomba pa1.4–1.55 µm.AgGaSe2 (AgGaSe) yakaratidzwa kuve inoshanda frequency yakapetwa kaviri kristaro kune infrared CO2 lasers mwaranzi.
Nekushanda pamwe chete nekutengesa kunowanikwa synchronously-pumped optical parametric oscillators (SPOPOs) muhurumende yefemtosecond uye picosecond, makristasi eAgGaSe2 akaratidza kushanda mune nonlinear parametric downconversion (difference frequency generation, DGF) munharaunda yeMid-IR.Iyo yepakati-IR isina mutsara AgGaSe2 crystal ine imwe yemhando huru dzekukodzera (70 pm2/V2) pakati pemakristasi anowanikwa mune zvekutengesa, ayo anopeta katanhatu kupfuura akaenzana neAGS.AgGaSe2 inodiwawo kune mamwe epakati-IR makristasi kune akati wandei zvikonzero.AgGaSe2, semuenzaniso, ine yakaderera nzvimbo yekufamba-kubva uye iri nyore kuwanikwa kuti irapwe kune chaiyo maapplication (kukura uye kucheka nzira, semuenzaniso), kunyangwe iine yakakura isina mutsara uye yakaenzana nzvimbo yakajeka.
Applications
● Generation yechipiri harmonics pamusoro CO uye CO2 - lasers
● Optical parametric oscilator
● Different frequency generator kusvika pakati infrared regions kusvika 17 mkm.
● Frequency kusanganisa pakati IR nharaunda
