1550nm快速可調(diào)諧激光器
RTL-1550是一個可調(diào)諧的激光光源，能夠快速地調(diào)諧波長跨過擴(kuò)展的C-波段(1520nm到1575nm)窗口。由一個外部電壓信號源或函數(shù)發(fā)生器驅(qū)動，它能產(chǎn)生動力學(xué)掃頻達(dá)到5kHz。RTL-1550是極其可靠的，并且不需要例行維護(hù)。
通過結(jié)合一個可靠的摻鉺光纖放大器(EDFA)和快速可調(diào)諧濾波器(TF)，RTL-1550提供了極好的邊模抑制比率(SMSR)50dB和30mW的高輸出。這些性能在光纖布拉格光柵(FBG)傳感器問訊系統(tǒng)、光相干系統(tǒng)和光學(xué)頻域范圍能夠有極好的信噪比。
