Wavelength stabilized single mode fiber coupled laser diode 500mW @ 980nm, SFBGLD-980-500
• FBG wavelength stabilized single mode laser.
• CW or pulsed operation.
• Low threshold current and high slope efficiency
• Operating temperature range -40 oC to +50°C.
• Wavelength/temperature coefficient 0.02nm/°C
• Built-in monitor photodiode, thermo-electric cooler and thermistor.
• Single mode fiber pigtail (Corning HI980, NA=0.21, MFD=4.2um@980nm) or PM fiber
• Optional FC/APC connector.
