Why Satellite Communication
Fiber-based platforms have become standard due to stability, compactness, and immunity to alignment issues compared to bulk lasers. They support long-term operation without frequent adjustments.
Single Frequency Lasers in Optical Satellite Communication
Optical communication is becoming central to satellite networks due to high data capacity and immunity to electromagnetic interference. A space communication laser delivers stable coherent light required for accurate modulation and long-range transmission, even in extreme thermal and mechanical environments.
Importance of High-Stability Lasers in Satellite Links
- Narrow linewidth for clean signal transmission
- Excellent frequency stability for long-distance links
- High beam quality for efficient free-space propagation
