激光二极管光束光源
型号：51nanoFI
品牌：Sch?fter + Kirchhoff
产品简介：激光二极管光束光源51nanoFI除了具有51nanoFCM具有低电源噪声，低相干长度以及低散斑比以外；51nanoFI集成了一个法拉第隔离器用于防止光的背反射。光返回到激光二极管将导致模式跳跃，噪声以及频率不稳定，并减少使用寿命
产品特点：
- 集成法拉第隔离器的光纤耦合半导体激光器
- 低相干长度低噪音
- 保偏单模光纤
- 波长 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)
产品应用：
1. 反粒子测试(Back-Reflection Particle Measurement?)
2. 法布里-佩罗特干涉(Fabry Perot Interferometry?)
3. 激光挠度测量(Laser Deflection Measurement?)
