Abstract
Devices, systems, and methods are provided for rapid laser recharging. A pulse emitting device may include an emitter to emit pulses, a first capacitor to provide pulses to the emitter, a second capacitor to charge the first capacitor, a first gate and a second gate to control the flow of current to the capacitors and the emitter, and a power supply configured to supply energy associated with the pulses. When the first gate is open, the first capacitor charges a first pulse of the pulses. When the first gate closes, the emitter emits the first pulse. When the first gate opens, the second gate closes and the second capacitor charges the first capacitor with a second pulse of the pulses. When the second gate opens after the second capacitor charges the first capacitor with the second pulse, the first gate closes and the emitter emits the second pulse.
