Thorlabs offers a selection of Benchtop Fiber Pigtailed Laser Sources that are ideal for fiber based applications from 635 nm to 1550 nm wavelengths. Our S1FC Series includes a pigtailed Fabry-Perot Laser Diode, while our S3FC Series models, available at 1310 nm and 1550 nm, use pigtailed DFB Laser Diodes.
S1FC Series Features
- Single Mode FC/PC Fiber Interface
- Low Noise, Highly Stable Output
- 5 Standard Models from 635 nm to 1550 nm
- Custom Wavelengths Available
The S1FC Series Fiber Coupled Laser Sources utilize an internally-pigtailed laser diode that is connected to the front panel FC feedthrough via a single mode fiber. By providing a fiber-to-fiber connection at the output, these devices typically deliver more useful optical power than systems that use a receptacle with embedded optics. All of our fiber pigtailed lasers utilize an angled fiber ferrule at the internal laser/fiber lauch point to minimize reflections back into the laser diode, thereby increasing the overall stability.
Both series feature keylock power switches and remoted interlock inputs, as well as an input for a 0 to 5 V analog signal for low frequency modulation or remote power adjustments.
S3FC Series Features
- Narrow Spectral Linewidths: <0.6 nm
- Thermo-Electric Temperature Stabilization
- 40 dB Optical Isolation
- Adjustable Temperature Set Point
- Adjustable Power
The S3FC Series Fiber Coupled Laser Sources feature a narrow linewidth DFB laser diode and a 40 dB optical isolator to eliminate back reflections and frequency jitter.
Additionally, the S3FC Series incorporates an integrated temperature control system for increased wavelength and power stability. The diode temperature can be adjusted using the front panel potentiometer, allowing limited wavelength tuning. |
