Cr:ZnSe

Cr:ZnSe激光晶體具有以下優(yōu)點(diǎn):通常沒(méi)有激發(fā)態(tài)吸收和上位能轉(zhuǎn)換,極寬的吸收帶和大的發(fā)射截面,在室溫下具有極好的熒光量子效率和超寬的發(fā)射寬度以及良好的化學(xué)和機(jī)械性能特性,使其成為高效,強(qiáng)大的可調(diào)諧中紅外激光的極佳來(lái)源。Cr:ZnSe激光晶體由于中紅外波段是大氣的窗口,因此在光通信、污染氣體檢測(cè)、工業(yè)燃燒產(chǎn)物測(cè)試等領(lǐng)域具有重要的應(yīng)用前景。

  • 廣泛的可調(diào)性(從2.1-3.1μm發(fā)射)
  • 寬吸收帶
  • 大增益截面(σ發(fā)射?9 × 10-19 cm2
  • 激發(fā)態(tài)吸收的最小問(wèn)題(不允許上能級(jí)激發(fā)態(tài)的自旋躍遷)
  • 高導(dǎo)熱性比YAG好(ZnSe為18w/m·K,YAG為13w/m·K)
  • 高IR(0.6-20μm)透明度
