激光二極管光束光源
型號：51nanoFI
品牌：Sch?fter + Kirchhoff
產(chǎn)品簡介：激光二極管光束光源51nanoFI除了具有51nanoFCM具有低電源噪聲，低相干長度以及低散斑比以外；51nanoFI集成了一個法拉第隔離器用于防止光的背反射。光返回到激光二極管將導致模式跳躍，噪聲以及頻率不穩(wěn)定，并減少使用壽命
產(chǎn)品特點：
- 集成法拉第隔離器的光纖耦合半導體激光器
- 低相干長度低噪音
- 保偏單模光纖
- 波長 405–1330 nm
- Spectral range 405 nm to 1550 nm
- Laser output power up to 27 mW
- Noise < 0.1% RMS (< 1 MHz)
- Integrated Faraday Isolator for feedback protection
- Output power adjustable with potentiometer or external voltage control input
- Modulation inputs for analog and TTL control (up to 100 kHz)
- Operation mode: constant power
- Coherence length 300 μm
- Beam profile is rotationally symmetric with a Gaussian intensity distribution
- Singlemode fiber cable or polarization-maintaining singlemode fiber cable (polarization aligned with connector index pin)
- FC-APC connector (8°-polish), optional DIN AVIO, ST or E-2000
- Fiber cable with strain relief and protective sleeving (?3 mm)
