29 Oct 2021 Cr:ZnSe – Chromium zinc selenide (Cr2+:ZnSe) exhibits high absorption coefficient and can be very efficiently pumped over broad 1450-2100 nm range of various sources or used as passive Q-switch in this range.
Unlike usually found in the market poly-crystalline form, 3photon Cr:ZnSe is mono-crystalline.
In the market most common Cr:ZnSe growing technology is Chemical Vapor Deposition (CVD)However, 3photon Cr:ZnSe is grown using other technologies in order to grow single crystal material. |
