Low-Coherence Laser Sources 51nanoFCM
Laser diode beam sources with single-mode or polarization-maintaining single-mode fiber cable
Laser diode beam sources of type 51nanoFCM have reduced power noise, reduced coherence length and low speckle contrast as a result of the internal RF modulation.
• Reduced speckle contrast
• Reduced coherence length: Coherence length≈ 300 μm
• Reduced power noise: < 0.1 % RMS (< 1 MHz)
• Various types from 405 nm to 1550 nm
• Laser output power up to 30 mW
• Output power adjustable with potentiometer or external voltage control input
• Modulation inputs for analog and TTL control (up to 100 kHz), details page 103
• Operation mode: constant power
• Beam profile is rotationally symmetric with Gaussian intensity distribution
• Single-mode fiber cable or polarization-maintaining fiber cable (polarization extinction ratio > 23 dB)
• 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 (Ø 3 mm)
• Laser safety measures conforming to IEC 825 / EN 60825-1
Option: laser diode beam source 51nanoFCM-N
OEM version without key switch nor interlock and not conforming to EN 60825-1.
