A first amplifier amplifies the seed pulses to produce amplified seed pulses and amplified spontaneous emission (ASE). An optical filter removes at least a portion of the ASE. A second amplifier amplifies the seed pulses to produce output pulses having a repetition frequency less than or equal to 100 MHz, a duration less than or equal to 20 nanoseconds, a duty cycle less than or equal to 1%, an energy greater than or equal to 10 nanojoules, a peak power greater than or equal to 1 watt, and an average power less than or equal to 50 watts, the ASE comprising less than or equal to 25% of the average power. A sensor head directs the output pulses into a field of view and detects reflected light therefrom."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pulsed laser for lidar system","description":"A lidar system with a seed laser to produce seed pulses with wavelengths between approximately 1400 nm and 2050 nm.
