Wavelength stabilized single mode fiber coupled laser diode 250mW @ 1440nm, SFBGLD-1440-250
• FBG wavelength stabilized single mode laser.
• CW or pulsed operation.
• Low threshold current and high slope efficiency
• Operating temperature range -40°C to +50°C.
• Wavelength/temperature coefficient 0.01nm/°C
• Built-in monitor photodiode, thermo-electric cooler and thermistor.
• Single mode (Corning SMF-28, NA=0.14, MFD=8.2um) or Polarization maintaining (Corning PM14xx, MFD=9.8+/-1um) fiber pigtail.
• Optional FC/APC connector.
