To improve the focal spot quality, output wavefront of Shenguang-II Upgrade facility is divided into four types based on spatial frequency and division band power spectral density. The influence each was quantitatively studied, results indicate that profile, energy concentration, peak intensity are mainly affected by low-spatial-frequency, relative sidelobes greatly both low- mid-spatial counterparts. peak-to-valley value should not exceed 2.27λ under requirement 50% enclosed within 3 times...
This study aims to update the existing SG PW laser system and improve temporal contrast shape fidelity of a compressed pulse with 150 fs level for multi-PW (5–10 PW). The design third-order dispersion (TOD) compensation via birefringent crystal was studied through numerical simulations experiments. dispersions introduced by were calculated using Jones matrix element changing in-plane rotation angle ϕ, thickness d, incident θ, temperature T, while also considering transmission spectral...
In this paper, the problem that aggregation of opinions for several individuals which are divided into two different subgroups is considered. Firstly, we establish a new model evolution all individual in system. Moreover, it's shown designed game admits unique Nash equilibrium. Secondly, by using matrix theory and theory, obtain sufficient condition consensus with co-evolution over time issues. Finally, simulation examples given to validate effectiveness theoretical results.
We demonstrated a scheme of bandwidth expansion and pulse shape optimized to afford 10 PW laser design via spectral shaping, which uses the existing Nd:glass amplifier chain SG laser. Compared amplified with gain-narrowing effect, required parameters injected energy, bandwidth, are analyzed, together their influence on system B -integral, energy output capability, temporal intensity contrast. A 7 nm by using LiNbO 3 birefringent shaping resulted in an 2 kJ proof-of-principle experiment. The...
In inertial confinement fusion laser device, the disposable debris shield is necessary to protect expensive optical elements from contaminations of target when high-energy PW was focused in terminal focusing system. While plate will have a very important impact on quality. this paper, design shield, system, studied by transmission theory, and parameters, such as PV value wavefront, thickness installation position plate, are optimized. If 95% focal spot energy concentrated within 10DL,...
