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 kutungamira, 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
