Low-Coherence Laser Sources 51nanoFI
Laser diode beam source with single-mode or PM-fiber cable and Faraday isolator
In addition to the laser diode beam source 51nanoFCM features (reduced power noise, reduced coherence length and low speckle contrast), the 51nanoFI additionally has an integrated Faraday isolator to protect the laser source from back- reflection.
• Reduced speckle contrast
• Reduced coherence length: Coherence length ≈300μm
• Reduced power noise: <0.1% RMS (<1MHz)
• Various Types from 405nm to 1550nm
• Laser output power up to 27mW
• 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 100kHz),
• Operation mode: constant power• Beam profile is rotationally symme tric with a Gaussian intensity distribution
• Single-mode fiber cable or polari za tion-maintaining single-mode fiber cable (polarization extinction ratio >23dB)
• FC-APC connector (8°-polish), optional DIN AVIO, ST or E-2000, end caps for wavelengths < 635 nm
• Fiber cable with strain-relief and protective sleeving (Ø3mm)
• Laser safety measures conforming to IEC 825 / EN 60825-1
Option: laser diode beam source 51nanoFI-N
OEM version without key switch nor interlock and not conforming to EN 60825-1.
