摘要
高功率激光是国之重器,随着激光功率的不断提升,热管理已成为制约高功率激光发展的关键技术瓶颈。本文围绕高功率激光热管理领域的重大需求与基础科学问题,系统梳理了材料、器件与系统三层级的热控策略与核心技术进展;进一步凝练出多物理场耦合机制、极端热输运瓶颈及量子亏损控制三大科学问题,并提出超高热导材料、高效热界面材料、微纳射流冷却、仿生散热等未来方向。通过“材料—器件—系统”多层级协同创新,结合AI驱动优化,有望突破散热极限,为空天通信、核聚变装置等国家重大工程提供高可靠性热管理解决方案,助力我国在全球高功率激光技术竞争中实现引领性突破。
High-power lasers,as national strategic assets,play a pivotal role in frontier scientific research.Thermal management has become a critical bottleneck limiting their development as laser power continues to escalate.This paper addresses the fundamental challenges and scientific issues in high-power laser thermal management by systematically reviewing strategies and technological advancements across three hierarchical levels:Materials,devices,and systems.Three core scientific issues are discussed and identified:Multi-physics coupling mechanisms,extreme heat flux transport limitations,and quantum defect control.Future research directions should be emphasized in aspects such as ultra-high thermal conductivity materials,high-efficiency thermal interface materials,micro/nano-jet cooling,and biomimetic thermal management.Through coordinated innovation across the“material-device-system”hierarchy and AI-driven optimization,breakthroughs in thermal dissipation limits are anticipated.These advancements will provide robust thermal solutions for national megaprojects such as aerospace communication and nuclear fusion,positioning China at the forefront of global high-power laser technology competition.
