Distributed Feedback Laser (Singlemode)
For gaz spectroscopy or trace gaz detection, single-mode, well-defined narrow linewidth lasers with precise tunability are required. For this purpose, quantum cascade lasers are built with a grating in the cavity that allow to exhibit an excellent single-mode behavior. DFB-QCLs can be precisely tuned with temperature (slow tuning) or current (quick tuning), and deliver a reasonable amount of output power.
- Operation in Continuous Wave or Pulsed mode
- See our stock of lasers!
- Lead time 2 weeks
- The lasers are mounted on different submounts and packaging:
- Room temperature or Cryogenic operation
- Output power:
- Average: 2 - 10 mW
- Peak : 100 - 500 mW
- Beam divergence (full angle):
- 60° perpendicular
- 40° parallel
- Operation equipment: Starter kit
Fabry-Perot Laser (Multimode)
In contrast to DFB singlemode lasers, the emission of Fabry-Perot (FP) QCLs is mainly multimode. Indeed, a FP-QCL is a laser whose emission spectrum is not adjusted by a grating. As result, the emission is mainly broad range.
