Daylight Solutions Tunable Laser - CW/Pulsed

Provides both Continuous Wave (CW) and Pulsed performance

Daylight Solutions

The Tunable CW/Pulsed External Cavity Quantum Cascade Laser (ECqcLâ„¢) system is the laboratory work horse, providing both Continuous Wave (CW) and Pulsed performance. Tuning ranges of many models have been expanded. The new HFQD control architecture allows for longer pulses and higher repetition rates as well as provides more chip protection and a more versatile modulation circuit for CW operation.

And now introducing over 100cm-1 of tunability at 3.25µm (3080cm-1) to probe hydrocarbon stretches!


  • Over 17 center wavelengths offered, including 3.25µm
  • HFQD control architecture
  • True CW or Pulsed operation
  • Expanded tuning ranges
  • High output powers
  • Narrow linewidths
  • Fully functional controller, including TEC, remote access
  • Room-temperature operation
