    Fiber Type:
    Output Power:

This is a red light laser diode with output wavelength at 650nm or 635nm. It has a high performance multi-quantum-well (MQW) laser diode chip, with pigtail or receptacle optical interface. Output power from 1mW to 10mW is available. (All output power refers to power from the fiber pigtail of 9/125 micron fiber.)


  • MQW 635 nm or 650 nm FP laser diode
  • Low threshold current
  • High output power (up to 10mW)
  • Built-in InGaAsP monitor photodiode
  • Wide operating temperature range (from -10 to +65 C degree)


  • Optical source
