    High Extraction Effiency, Nanosecond Bidirectional Ring Amplifier with Twin Pulses
    Author(s): Yuan

     Laser amplifier has been widely used in the field of scientific research, laboratory astrophysics and inertial confinement fusion (ICF), etc. The multi-pass amplifier (MA) is widely used in high-power laser systems such as ICF drivers, which requires expensive preamplifier systems to compensate for the limited gain of the main amplifiers. Besides, the laser system in MA should operate at high fluence to achieve high extraction efficiency, which results in a technical challenge in the damage of optical components under high-power lasers irradiation. To efficiently extract the stored energy with low injection energy at low laser fluence operation and make the system compact, a bidirectional ring amplifier (BRA) with twin pulses is proposed. The characteristics of the bidirectional ring amplifier on energy flow, extraction efficiency and output energy capability are studi.. View More»
