Laser Diode Beam Source 58FCM

Fiber-coupled laser source with single-mode or polarization-maintaining fiber cables

Laser diode beam sources of type 58FCM are fiber-coupled laser sources with single-mode or polarization-maintaining fiber cables

  • Various wavelengths from 405 nm to 1550 nm
  • Laser output power up to 70 mW
  • Output power adjustable with potentiometer or external voltage control input
  • Operation mode: constant power (standard) or constant current
  • Beam profile is rotationally symmetric with Gaussian intensity distribution
  • Modulation inputs for analog and TTL control (up to 100 kHz)
  • 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 protect. sleeving (Ø 3mm)
  • Laser safety measures conforming to IEC 825 / EN 60825-1


  • To fullfill lower laser safety requirements (e.g. laser class 2), the laser source can be delivered with reduced maximum output power
  • Supply voltage 5 V DC (standard) or 12 V DC (some with 12 V DC only), reverse voltage protection
  • Protective cap to prevent damage to the potentiometer
