1550nm Ultra-Narrow Linewidth Laser Module with SOA (3kHz, 100mW) | DVS-Ready, No AOM Needed
This 100mW high-power laser module features an integrated SOA (Semiconductor Optical Amplifier) for efficient power amplification. It supports direct pulse modulation of the seed light, making it the perfect light source for DVS (Distributed Vibration Sensing) systems. A key advantage is the elimination of external AOM (Acousto-Optic Modulator), significantly simplifying your system architecture and reducing overall costs.
