Ultra-narrow Linewidth Lasers
Chilas design and fabricate external cavity semiconductor lasers using its leading hybrid integration technology. They make ultra-narrow linewidth lasers which offer a very competitive price compared to lasers with similar specifications.
The CT3 and CT3+ lasers have a wide tuning range without jumps and have an ultra-narrow linewidth, a unique combination. This allows them to have swept source functionality which is perfect for a wide range of applications.
The operating wavelengths of the lasers and their possible applications are listed below. Please get in touch with one of our experts if you require a custom laser.
The tuneable CT3 and CT3+ lasers. Operating wavelength: 1550 nm, tuneable from 1490 nm – 1580 nm (CT3) or – 1590 nm (CT3+).
- Quantum key distribution
- Optic fibre sensor integrator
- Telecom instrumentation
- Atomic clock
The fixed wavelength CF3 laser. Operating wavelength: 1550 nm ± 5 nm.
- Optic fibre sensor
- Wind LiDAR
The ultra-narrow linewidth and the wide tunability range make Chilas lasers ideal for communications applications, such as Datacom and satellite communications, or for LiDAR applications in the automotive industry, robots and wind LiDAR.
The very broad tuning range, the swept source functionality and the small footprint of the CT3 lasers all make these lasers unique. They allow you to have more sensors on a single fibre and to perform in the range of applications listed above
Advantages of Chilas’ Lasers:
Low cavity loss and a long optical cavity length mean Chilas’ laser can achieve high output power (>40 mW) and ultra-narrow linewidth (<1 kHz).
The lasers are housed in a compact, 14-pin butterfly package to enable compatibility with any standard 14-pin laser diode mount.
The intuitive software has adjustable sliders to easily tune and calibrate wavelengths and adjust the output power. The software then loads the data into a .csv file for further processing.
Some of the other advantages are listed below:
- Ultra-narrow linewidth
- Very wide tuning range
- Small footprint/size
- Proven long-term reliability
- Built-in TEC
- PM pigtail
