激光二极管光束光源51nanoFI

激光二极管光束光源

型号：51nanoFI

品牌：Schäfter + 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 (Ø3 mm)
