摘　　要：对利用激光进行霍金-安鲁辐射实验的研究现状和实验挑战点等方面进行综述。霍金-安鲁辐射是量子引力理论的重要推论之一。对其进行实验观测研究,将对量子引力理论、大统一理论、乃至万物终极理论的发展具有重要推动作用。霍金-安鲁辐射可以通过强激光、储存环、潘宁阱、声学、玻色-爱因斯坦凝聚等各种实验手段加以研究,其中借助强激光有两类方法:人工光学黑洞和强激光加速。前者是利用介质的非线性效应,产生一个光波传播的视界,进而对视界附近的量子现象,包括霍金-安鲁辐射,进行研究;后者是利用超强激光场对电子施加的超高加速度来研究电子的霍金-安鲁辐射等特性。Methods, as well as challenges, in experimental studies on Hawking-Unruh radiation(HUR) with high-intensity laser(HIL) will be reviewed in this paper. Hawking-Unruh radiation is one of the most important effects in quantum gravity. Experimental studies on it are critical for the development of quantum gravity theories, or theories like the Theory of Everything etc. Various experimental methods have been developed to study the HUR, including high-intensity laser, storage ring, Penning trap, Bose-Einstein condensate, acoustic methods etc. There are two major types of HUR studies with HILs today, the artificial optical blackhole method and the laser acceleration method. In the1st method, nonlinear properties of optical media are used to generate artificial blackholes as platforms for studies on related phenomena including HUR. In the 2nd method, electrons ’ HUR radiation spectra under extreme HILs are expected.
