| 1450nm快速可調(diào)諧激光器
RTL-1450是一個(gè)掃描激光光源，能夠快速地從1450nm調(diào)諧到1550nm窗口。由一個(gè)外部電壓信號(hào)源或函數(shù)發(fā)生器驅(qū)動(dòng)，它能夠產(chǎn)生動(dòng)力學(xué)掃頻達(dá)到5kHz。RTL-1450是極其可靠的，并且不需要例行維護(hù)。
由于使用外腔激光設(shè)計(jì)和快速可調(diào)諧濾波器(TF)，RTL-1450提供極好的邊模抑制率(SMSR)40dB和20mW高輸出功率。這些性能在光纖布拉格光柵(FBG)傳感器問訊系統(tǒng)、光學(xué)相干斷層掃描、光相干系統(tǒng)和光學(xué)頻域范圍能夠有極好的信噪比。
