Abstract：To address the critical demand for a highly stable observation environment in the study of laser-material inter-
actions under vacuum conditions，this paper proposes a novel cubic vacuum chamber design based on the theory of non-circu-
lar cross-section pressure vessels. Conventional cylindrical chambers，while structurally efficient，often impose constraints on
multi-axial optical access and system integration. This cubic design paradigm aims to better accommodate the geometric
and functional requirements of advanced optical experimental setups. The structural design of the cubic vessel was
conducted in strict compliance with the national pressure vessel code GB/T 150.3—2024. Its mechanical perfor-
mance was rigorously validated through three-dimensional finite element analysis （FEA） under simulated external pres-
sure loads. A key aspect of this simulation was the systematic investigation into the complex three-dimensional discontinuous
stress transfer and concentration mechanisms prevalent in the chamber's corner regions. This detailed analysis provided criti-
cal insights into stress hotspots that are often neglected by simplified analytical models，forming the foundation for targeted
structural enhancements. To ensure optical clarity and maintain vacuum integrity， an acrylic-metal composite observation
window was designed and integrated. The parameters of this window assembly were optimized through a comprehensive ap-
proach that accounted for the long-term creep behavior of the acrylic viewport under vacuum and the deformation compatibil-
ity criterion at the critical metal-to-acrylic sealing interface. This dual consideration guarantees both a reliable，durable seal
and minimal optical distortion throughout extended operational cycles. A parallel cost-benefit analysis of various wall-thick-
ness schemes for the main chamber body was performed. This study revealed a pronounced nonlinear relationship between
