Chilas CT3 external cavity tunable laser (ECL)
The Chilas CT3 is a C-band external cavity laser (ECL) in a standard 14-pin butterfly package, offering ultra-narrow linewidth below 1 kHz and a wide tuning range of 100 nm. Designed for OEM integration, the CT3 is the right choice for customers who need a bare, high-performance laser component for their own system.

Key features
- Ultra-narrow linewidth < 1 kHz
- 14-pin butterfly package with PM pigtail (FC/APC)
- Wide tuning range of 100 nm across the C-band
- Built-in TEC for temperature stabilisation
- Mode-hop-free tuning > 0.25 nm
- Proven long-term reliability
- Output power >10 dBm
Applications
- Telecommunication and coherent communications
- Gas sensing and spectroscopy
- Optical coherence tomography (OCT)
- LiDAR
- OEM laser integration

Ordering Information
• Minimum order quantity: 10 units
Need fewer than 10? We understand that’s not always possible, get in touch and we’ll see what we can do.
• Looking for a complete laser module?
The CF3 is a bare component for OEM integration. If you need a ready-to-use module with electronics, software control, full connectivity, and no moving parts, you might want to take a look at our standard laser products:
→ ATLAS 1550 — C-band narrow linewidth tunable laser module
→ COMET — C-band swept source laser module
→ POLARIS — frequency-stabilized single-frequency laser module
