Problems solved by technology

For the seed source, the oscillator has the disadvantages of large size, poor frequency stability, and large time jitter, which often bring great harm to the stability and all-optical synchronization of the optical parametric chirped pulse amplification laser system.

Moreover, when the seed pulse is transmitted in space, due to the poor stability of the optical frame and the influence of the environment, the shape of the optical pulse will change, accompanied by large time jitter, etc. These unfavorable factors will seriously affect the optical parameters. The optical synchronization and system stability of the chirped pulse amplification laser system also limit the applicable environment of the OPCPA amplification system
