L波段可調(diào)諧波長(zhǎng)激光器 TWL-L
TWL-L系列是高光譜純度和非常穩(wěn)定的可調(diào)諧波長(zhǎng)激光光源。TWL-L特征是寬的波長(zhǎng)調(diào)諧范圍、窄的激光線寬、高邊模抑制比(SMSR)、極好的波長(zhǎng)穩(wěn)定性和超過(guò)20mW的光學(xué)輸出。具有標(biāo)準(zhǔn)的偏振維護(hù)(PM)光纖輸出，TWL-L提供線偏振輸出。這些特征使TWL-L很好地適合許多不同應(yīng)用，包括DWDM器件試驗(yàn)、光傳感和實(shí)驗(yàn)室測(cè)量應(yīng)用。
TWL可調(diào)諧激光器可用在一個(gè)標(biāo)準(zhǔn)的1U 19"機(jī)架式儀器箱中。它包括易于使用的Labview控制軟件和RS232接口在實(shí)驗(yàn)室環(huán)境遠(yuǎn)程操作。
