Abstract
In this work, we present a compact size and highly efficient nanosecond pulsed 1550nm single mode fiber laser that can operate from -40C to +95C. The laser generates 2 to 10 ns pulses at a repetition rate of hundreds kHz to a few MHz with hundreds to kilowatt peak power. The design of this laser is optimized to achieve over 10% wall-plug efficiency at room temperature with an ultra-low ASE noise less than 1%. The performance is also well maintained with less than 30% EO (electrical-optical) efficiency degradation at extreme temperatures and demonstrates high reliability consistent with deployment into harsh environments.The robust performance makes the laser an ideal source for lidar and sensing applications, along with other medical, scientific, and industrial applications.
