We developed a high power and high efficiency 1.55 μm fiber laser for eye-safe autonomous driving lidars. A drive current directly modulated DFB laser provides a seed pulse selectable from 2 ns to 10 ns. A high gain (47 dB), low ASE noise (-23 dB), and cladding-pumped multi-pass fiber amplifier is designed and used as the power amplifier. The laser can deliver laser pulses from 80 kHz to 10 MHz with peak powers greater than 5 kW, and pulse energy more than 10 uJ with a single output mode of M2 = 1.05. The laser works in -40 °C to approximately 105 °C environment temperature range with total consumed electrical power ⪅10 W.
