Laser diode beam source 51nanoFCM

Laser diode beam source 51nanoFCM-…

Laser diode beam source 51nanoFCM-…

with singlemode or polarization-maintaining singlemode 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. The laser diode beam source 51nanoFCM-… can be used for atomic force microscopy (AFM) and as a pilot laser during alignment applications.

Performance Features:

  • Spectral range 405 nm to 1550 nm
  • Laser output power up to 30 mW
  • Noise <0.1 % RMS (<1 MHz)
  • 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 Gaussian intensity distribution
  • Singlemode fiber cable or polarization-maintaining singlemode fiber cable (polarization aligned to connector key index)
  • FC-APC connector (8°-polish), optional DIN AVIO, ST or E-2000
  • Fiber cable with strain relief and protective sleeving (Ø3 mm)
