Product Description

Mid-IR DFB Lasers for Spectroscopy


NORCADA designs and manufactures single mode semiconductor distributed feedback (DFB) lasers for industrial sensing and environmental monitoring applicaons. Our DFB lasers come with two main styles of hermetic packaging configurations designed for excellent temperature stability and wavelength tuning.


Mid-IR DFB Lasers Product Features
• Integrated DFB grating provides single frequency operation
• Frequency tuning can be accomplished by adjusting either laser drive current or temperature.
• Tuning range up to 6 nm without mode hopping
• Temperature tuning control: 0.1 nm / ℃
• Drive current tuning control: 0.04 nm / mA
• Typical output power range: 2-8 mW


Mid-IR DFB Lasers Packaging Options
• TO-66 package
• Glass or Sapphire window with 7°slope
• Hermetically sealed Integrated thermoelectric cooler (TEC)
• Mounted lens for collimation
• Butierfly package with fibre coupled output


Mid-IR DFB Lasers Applications
• Molecular spectroscopy
• Industrial gas sensing (TDLAS)
• Environmental monitoring
